KAIST Develops Microbially Produced Adhesive Materials from Glucose Instead of Petroleum
KAIST researchers have demonstrated the potential of using microorganisms to produce a bio-based alternative to petroleum-derived materials for hot-melt adhesives. These heat-activated glues are widely used in packaging, furniture, electronics, and automobiles. Using Escherichia coli, the team produced a new polymer from glucose and demonstrated adhesive performance and thermal properties that support its potential use as a hot-melt adhesive.
KAIST (President Choongsik Bae) announced on September 17 that a research team led by Distinguished Professor Sang Yup Lee from the Department of Chemical and Biomolecular Engineering developed a microbial cell factory by engineering E. coli to produce the new aromatic polyhydroxyalkanoate (PHA) polymers from glucose for adhesive applications.
The research team applied systems metabolic engineering, an approach that redesigns a microorganism's overall metabolism to produce a target compound, to re-engineer the metabolic pathways of E. coli. Through this approach, the researchers successfully produced two new adhesive materials from glucose, poly(4HB-co-PhLA) and poly(3HB-co-4HB-co-PhLA), both belonging to the PHA family of biodegradable polymers.
Adhesives are essential materials used in a wide range of industries, including packaging materials, electronics, automobiles, and construction materials. In particular, hot-melt adhesives (HMAs) are solid adhesives that are melted with heat for bonding and then solidify as they cool. Because they do not require separate organic solvents and enable rapid bonding, they are widely used in industry.
However, most hot-melt adhesives currently in use are based on petroleum-derived polymers such as ethylene-vinyl acetate (EVA). Although they offer excellent adhesive performance, most do not readily degrade in nature and can cause waste and microplastic problems. In particular, even when biodegradable packaging materials are used, if the adhesive does not degrade, the biodegradability and recyclability of the entire product may be reduced.
To address this problem, the research team focused on PHA, a type of biodegradable plastic produced by microorganisms. PHA can be produced by microorganisms using renewable feedstocks such as glucose. It also has the advantage that properties such as polymer flexibility, strength, and heat resistance can be adjusted in various ways depending on which components are included and in what proportions.
Using this principle, the research team incorporated 4-hydroxybutyrate (4HB) and phenyllactate (PhLA) into a single polymer. 4HB contributes to the material’s softness and adhesion, while PhLA increases the material’s rigidity and heat resistance. When the research team varied the relative proportions of the two components, the thermal properties and adhesive performance of the polymers also changed. In particular, polymers containing approximately 24–34 mol% 4HB showed excellent adhesive performance.
The research team designed intracellular metabolic pathways so that E. coli consumes glucose, produces 4HB and PhLA on its own, and then links them together into polymers.
To address metabolic imbalances that arise when multiple monomers are produced simultaneously, the team adjusted the strength and timing of gene expression, added a CoA transferase to facilitate the reactions, and used a genome-scale metabolic model to identify and optimize metabolic pathways associated with insufficient precursor supply and production bottlenecks.
As a result, through fed-batch fermentation, in which nutrients are continuously supplied during microbial cultivation, the team successfully produced 10.2 g of poly(4HB-co-PhLA) per liter of culture medium. By additionally introducing a biosynthetic pathway for producing 3HB, the team successfully produced up to 52.8 g/L of poly(3HB-co-4HB-co-PhLA).
The research team also tested whether the produced polymers could be used as hot-melt adhesives.
In a lap shear adhesion test using stainless steel as the substrate, poly(4HB-co-PhLA) recorded a lap-shear strength of 4.58 MPa. This is higher than the 4.20 MPa achieved by a commercial EVA adhesive. Poly(3HB-co-4HB-co-PhLA) also showed performance comparable to EVA in a wood adhesion test.
In addition, poly(4HB-co-PhLA) retained a substantial level of adhesive strength even after repeated melting and rebonding. The incorporation of the PhLA component improved heat resistance.
Furthermore, after treatment with lipase, an enzyme that breaks down fats, surface damage to the polymers was observed, while the molecular weight and overall mass of the polymers also decreased. These results indicate that the newly developed aromatic PHA can be degraded by enzymes.
This study is significant not only for the development of an eco-friendly adhesive but also for demonstrating the potential of metabolic engineering to produce functional materials with tunable properties. Going forward, this approach could be extended into a biomanufacturing technology that tunes polymer properties, such as adhesion strength, flexibility, and heat resistance, to meet specific application needs, and produces such materials using microorganisms.
The approach also makes it possible to produce functional polymers that have traditionally been produced through petrochemical processes, from renewable feedstocks such as glucose instead. This is expected to serve as a sustainable production technology not only for adhesives but for a wide range of functional polymer materials going forward.
Distinguished Professor Sang Yup Lee said, “This study demonstrates that by engineering microbial metabolism, it is possible to go beyond simply producing polymers and directly produce functional materials,” adding, “In the future, by utilizing various non-natural monomers and microbial cell factories, this approach could be expanded into biomanufacturing technologies for the sustainable production not only of petroleum-based adhesive alternatives but also of a wide range of functional polymers.”
The study, co-authored by Ph.D. student Minju Kang, Dr. Youngjoon Lee, and Dr. Gi Bae Kim of the KAIST Department of Chemical and Biomolecular Engineering, was published online on July 20 in the international journal Nature Communications.

KAIST and Samsung Heavy Industries Launch Advanced Maritime Research Center, Marking 32 Years of Industry–Academia Collaboration
KAIST (President Choongsik Bae) announced that it held an opening ceremony for the SHI–KAIST Advanced Maritime Research Center (AMRC) with Samsung Heavy Industries (Vice Chairman and CEO Sung-an Choi) on August 13 at the John Hannah Hall in KAIST Academic Cultural Complex on its main campus in Daejeon.
The new center marks a major milestone in the 32-year industry–academia partnership between the two institutions, which dates back to 1995. Building on more than three decades of joint research and mutual trust, KAIST and Samsung Heavy Industries are expanding their partnership through a joint research hub dedicated to developing key technologies for the future of the shipbuilding and offshore industries.
Through the center, the two institutions will jointly develop technologies that address industry needs in areas including AI, robotics, and green technologies. They will also work to bring research outcomes into industrial applications and develop highly skilled professionals.
“Physical AI that drives innovation in real-world industrial settings will be a determining factor in manufacturing competitiveness,” said KAIST President Choongsik Bae. “The shipbuilding and offshore industry is a prime field for creating new value through the convergence of mechanical engineering, AI, and robotics. I hope the center will grow into a research hub that addresses challenges facing industry and sets new benchmarks for future technologies.”
“It is especially meaningful to see our 32 years of collaboration with KAIST culminate in the establishment of the Advanced Maritime Research Center,” said Sung-an Choi, Vice Chairman and CEO of Samsung Heavy Industries. “We will further accelerate our efforts to secure technological competitiveness and foster talent for the future shipbuilding and offshore industry in areas including autonomous navigation, eco-friendly vessels, and smart manufacturing.”
To secure key technologies for the future shipbuilding and offshore industry, the center will conduct joint research in four areas. AI technologies for autonomous operation and intelligent navigation; propulsion systems using zero- and low-carbon fuels; manufacturing innovation for smart shipyards and digital twins; and robotics specialized for shipbuilding and offshore applications.
In autonomous navigation, researchers will develop AI algorithms for advanced autonomous navigation systems, including technologies for situational awareness, optimal route planning, and collision avoidance. The center will also conduct research on zero- and low-carbon fuels in response to international efforts toward carbon neutrality and the green transition of the shipping and shipbuilding industries. This work will focus on key vessel components and fuel-supply technologies for clean fuels such as ammonia and hydrogen.
In the area of smart shipyards, the center will use AI and digital twin technologies to optimize complex shipbuilding processes, including block erection and production management. This research aims to improve productivity and quality while reducing costs and energy consumption. In specialized maritime robotics, researchers will develop technologies to automate demanding on-site tasks such as welding, painting, and inspection. These technologies will help address the decline in the working-age population while improving worker safety and production efficiency.
Beyond technology development, the center will serve as a hub for training specialists who will lead the future maritime industry. The two institutions will use industry–academia cooperation funding and other resources to support student research and scholarship programs. They will also expand personnel exchange programs connecting industrial sites and research laboratories, thereby continuously fostering research talent with the practical, industry-relevant capabilities needed in the field.
The center was established on the foundation of more than three decades of cooperation between the two institutions. Their partnership began in 1995, when Samsung Heavy Industries’ Ship & Offshore Research Institute and KAIST’s Department of Mechanical Engineering established the SHI–KAIST Industry–Academia Cooperation Council. Since then, they have conducted joint research spanning the shipbuilding and offshore engineering fields—including structures, fluid dynamics, cryogenics, green technologies, smart ships, and autonomous navigation—and accumulated a broad base of foundational technologies.
The institutions have continued to strengthen the connection between research and industry through initiatives such as the Advisory Board program, industry-tailored courses, and joint SEED research projects. The number of collaborative projects and technical consulting cases conducted through the Advisory Board program has exceeded 1,000. The two institutions have also maintained active personnel exchanges through short-term researcher training and cooperative education programs.
Approximately 50 people attended the opening ceremony to celebrate the launch of the center, including KAIST President Choongsik Bae, faculty members and professors emeriti from the Department of Mechanical Engineering, Samsung Heavy Industries Vice Chairman and CEO Sung-an Choi, and other executives and officials.
KAIST’s Solarstill Box Wins Red Dot’s Highest Honor for Producing Clean Water Using Only Sunlight
A KAIST design that produces clean drinking water using only sunlight, without electricity or fuel, has won one of the world’s most prestigious design awards. The design received high international recognition not only for its technical completeness, but also for its sustainable approach, which enables residents in regions affected by water scarcity and water pollution to produce and manage clean water on their own.
KAIST (President Choongsik Bae) announced on the 17th of July that “Solarstill Box,” a solar-powered water purification and desalination device developed by a research team led by Professor Sangmin Bae from the Department of Industrial Design, has won the “Red Dot: Best of the Best” award in the Social Impact category at the Red Dot Award: Design Concept 2026, a globally renowned design competition.
The Red Dot Design Award is considered one of the world’s three major design awards, along with Germany’s iF Design Award and the United States’ IDEA (International Design Excellence Awards). Among them, the “Best of the Best” is the highest distinction, awarded to works that demonstrate the greatest innovation and completeness in each category.
This award is significant because it goes beyond recognition of product design excellence. It represents international acknowledgment that design can help address the shared human challenge of clean water access and create sustainable social value.
Solarstill Box is a low-cost water purification and desalination device that converts seawater or water containing salt and pollutants into drinking water through solar distillation. It was developed for coastal areas, saline regions, and off-grid communities that rely on contaminated water sources. The device is designed to produce clean water using only solar energy, without electricity, fuel, or separate filters.
The stepped trays inside the device increase the surface area for evaporation, improving the efficiency of solar distillation. As evaporated water vapor condenses on the transparent cover, contaminants such as salt, heavy metals, and bacteria are naturally separated, allowing only clean water to be collected.
Solarstill Box is also made of flat components based on Plaveneer sheets, allowing it to be produced and transported in a flat-pack format. Anyone can assemble it locally in about 20 minutes, and maintenance costs are reduced because only damaged parts need to be replaced. Another key feature is that it moves beyond the one-time delivery of relief supplies and instead creates a sustainable drinking water system that local residents can install and manage themselves.
Solarstill Box was developed as part of the “SEED Project,” a social contribution design research project by ID+IM Design Lab, led by Professor Sangmin Bae of the Department of Industrial Design, in collaboration with World Vision. Following this award, the research team plans to work with World Vision to pursue product commercialization and establish local distribution models. In the long term, the team aims to expand the project into a cooperative-based operating model in which local residents directly participate in manufacturing, distribution, and maintenance, thereby supporting both clean water access and sustainable community development.
The project aimed to improve access to clean drinking water in low-resource regions where water scarcity and pollution make it difficult to secure safe water. The design development was carried out by Professor Sangmin Bae, doctoral student Jungwoo Kim, master’s student Minsu Kim, and undergraduate student Seunghee Han.
Professor Sangmin Bae said, “Design should go beyond creating beautiful products; it should serve as a tool for solving social problems and changing people’s lives,” adding, “We hope Solarstill Box will provide practical help to communities in need of clean water and spread as a sustainable drinking water system that residents can operate on their own.”
Solarstill Box will be introduced to a global audience through the official award ceremony and exhibition of the Red Dot Award: Design Concept 2026, which will be held in October.
KAIST Study Finds Politically Salient Immigration Issues Can Lead to Higher Industrial Pollution
When immigration or refugee issues become heated political topics, nearby factories may end up releasing more toxic substances. Although the two phenomena may appear unrelated, a KAIST-led international research team has found that they are in fact connected through the government’s limited administrative and fiscal resources.
KAIST (President Choongsik Bae) announced on the 10th of July that a joint research team led by Professor Narae Lee from The School of Business and Technology Management at KAIST, in collaboration with Professor Heli Wang from Singapore Management University (SMU), analyzed immigration-related legislation and environmental data across the United States and found that when immigration becomes a central political agenda, government environmental oversight weakens and firms’ toxic chemical releases increase. The research team describes this phenomenon as “institutional crowding.”
Government administrative capacity and budgets are not unlimited. When a new political issue emerges, government attention and resources become concentrated in that area. In the process, enforcement in relatively less visible policy areas, such as environmental oversight, may weaken. Although the research team analyzed immigration as a case study, they explain that this phenomenon is not limited to a specific issue. Rather, it represents a general mechanism that can arise when political agendas compete for limited government resources.
The research team combined data from the U.S. Environmental Protection Agency’s Toxics Release Inventory (TRI) with immigration-related legislative data from U.S. states. By analyzing a total of 82,377 observations collected from 14,390 manufacturing facilities across the United States between 2010 and 2018, the team found that each additional immigration-related bill was associated with an average increase of about 1% in toxic chemical releases per manufacturing facility. This is equivalent to approximately 25 kilograms, or 56 pounds, of additional toxic emissions per facility.
The researchers found that this increase was not caused by a relaxation of environmental regulatory standards. Rather, it occurred because firms reduced costly efforts to cut pollution and treat toxic waste as government environmental oversight became relatively less effective.
This pattern was especially pronounced in states facing fiscal constraints. In states with high debt or heavy fiscal burdens, environmental oversight weakened further when political attention shifted to new issues.This suggests that when government budgets are tight, resources are more likely to be allocated first to politically urgent issues, while environmental monitoring may be pushed down the priority list.
Professor Narae Lee said, “This study does not argue that immigration causes environmental pollution. Rather, it shows that shifts in the political agenda item can weaken environmental oversight and thereby increase corporate pollution,” adding, “Even when limited government resources are concentrated on a particular issue, environmental oversight needs to be institutionally protected so that it remains stable.”
The study is significant in that it empirically identifies how competition among political agendas can affect firms’ environmental pollution management. It also offers new implications for public policy and for advancing environmental justice, so that the burden of environmental pollution does not fall disproportionately on socially vulnerable groups.
The research was published online on May 29 in the Journal of Management, a leading international journal in the field of management, with Professor Narae Lee as the first author.
An earlier version of the paper received the POSCO Corporate Citizenship Research Award, the Robert J. Litschert Award from the Academy of Management, and the Best Paper with Practical Implications Award from the Strategic Management Society, recognizing the excellence and practical significance of the research.

Breaking Performance Barriers of All Solid State Batteries
< (Bottom, from left) Professor Dong-Hwa Seo, Researcher Jae-Seung Kim, (Top, from left) Professor Kyung-Wan Nam, Professor Sung-Kyun Jung, Professor Youn-Seok Jung >
Batteries are an essential technology in modern society, powering smartphones and electric vehicles, yet they face limitations such as fire explosion risks and high costs. While all-solid-state batteries have garnered attention as a viable alternative, it has been difficult to simultaneously satisfy safety, performance, and cost. Recently, a Korean research team successfully improved the performance of all-solid-state batteries simply through structural design—without adding expensive metals.
KAIST announced on January 7th that a research team led by Professor Dong-Hwa Seo from the Department of Materials Science and Engineering, in collaboration with teams led by Professor Sung-Kyun Jung (Seoul National University), Professor Youn-Suk Jung (Yonsei University), and Professor Kyung-Wan Nam (Dongguk University), has developed a design method for core materials for all-solid-state batteries that uses low-cost raw materials while ensuring high performance and low risk of fire or explosion.
Conventional batteries rely on lithium ions moving through a liquid electrolyte. In contrast, all-solid-state batteries use a solid electrolyte. While this makes them safer, achieving rapid lithium-ion movement within a solid has typically required expensive metals or complex manufacturing processes.
To create efficient pathways for lithium-ion transport within the solid electrolyte, the research team focused on "divalent anions" such as oxygen and sulfur . Divalent anions play a crucial role in altering the crystal structure by integrating into the basic framework of the electrolyte.
The team developed a technology to precisely control the internal structure of low-cost zirconium (Zr)-based halide solid electrolytes by introducing these divalent anions. This design principle, termed the "Framework Regulation Mechanism," widens the pathways for lithium ions and lowers the energy barriers they encounter during transport. By adjusting the bonding environment and crystal structure around the lithium ions, the team enabled faster and easier movement.
To verify these structural changes, the researchers utilized various high-precision analysis techniques, including:
High-energy Synchrontron X-ray diffraction(Synchrotron XRD)
Pair Distribution Function (PDF) analysis
X-ray Absorption Spectroscopy (XAS)
Density Functional Theory (DFT) modeling for electronic structure and diffusion.
The results showed that electrolytes incorporating oxygen or sulfur improved lithium-ion mobility by 2 to 4 times compared to conventional zirconium-based electrolytes. This signifies that performance levels suitable for practical all-solid-state battery applications can be achieved using inexpensive materials.
Specifically, the ionic conductivity at room temperature was measured at approximately 1.78 mS/cm for the oxygen-doped electrolyte and 1.01 mS/cm for the sulfur-doped electrolyte. Ionic conductivity indicates how quickly and smoothly lithium ions move; a value above 1 mS/cm is generally considered sufficient for practical battery applications at room temperature.

< Atomic Rearrangement of Solid Electrolyte for All-Solid-State Batteries (AI-generated image) >
Professor Dong-Hwa Seo stated, "Through this research, we have presented a design principle that can simultaneously improve the cost and performance of all-solid-state batteries using cheap raw materials. Its potential for industrial application is very high." Lead author Jae-Seung Kim added that the study shifts the focus from "what materials to use" to "how to design them" in the development of battery materials.
This study, with Jae-Seung Kim (KAIST) and Da-Seul Han (Dongguk University) as co-first authors, was published in the international journal Nature Communications on November 27, 2025.

Automatic C to Rust Translation Technology Gains Global Attention for Accuracy Beyond AI
<(From Left) Professor Sukyoung Ryu, Researcher Jaemin Hong>
As the C language, which forms the basis of critical global software like operating systems, faces security limitations, KAIST's research team is pioneering core original technology research for the accurate automatic conversion to Rust to replace it. By proving the mathematical correctness of the conversion, a limitation of existing Artificial Intelligence (LLM) methods, and solving C language security issues through automatic conversion to Rust, they presented a new direction and vision for future software security research. This work has been selected as the cover story for CACM, the world's highest-authority academic journal, thereby demonstrating KAIST's global research leadership in the field of computer science.
KAIST announced on the 9th of November that the paper by Professor Sukyoung Ryu's research team (Programming Language Research Group) from the School of Computing was selected as the cover story for the November issue of CACM (Communications of the ACM), the highest authority academic journal published by ACM (Association for Computing Machinery), the world's largest computer society.
<Photo of the Paper Selected for the Cover of Communications of the ACM>
This paper comprehensively addresses the technology developed by Professor Sukyoung Ryu's research team for the automatic conversion of C language to Rust, and it received high acclaim from the international research community for presenting the technical vision and academic direction this research should pursue in the future.
The C language has been widely used in the industry since the 1970s, but its structural limitations have continuously caused severe bugs and security vulnerabilities. Rust, on the other hand, is a secure programming language developed since 2015, used in the development of operating systems and web browsers, and has the characteristic of being able to detect and prevent bugs before program execution.
The US White House recommended discontinuing the use of C language in a technology report released in February 2024, and the Defense Advanced Research Projects Agency (DARPA) also explicitly stated that Rust is the core alternative for resolving C language security issues by promoting a project to develop technology for the automatic conversion of C code to Rust.
Professor Sukyoung Ryu's research team proactively raised the issues of C language safety and the importance of automatic conversion even before these movements began in earnest, and they have continuously developed core related technologies.
In May 2023, the research team presented the Mutex conversion technology (necessary for program synchronization) at ICSE (International Conference on Software Eng), the top authority conference in software engineering. In June 2024, they presented the Output Parameter conversion technology (used for result delivery) at PLDI (Programming Language Design and Implementation), the top conference in programming languages, and in October of the same year, they presented the Union conversion technology (for storing diverse data together) at ASE (Automated Software Eng), the representative conference in software automation.
These three studies are all "world-first" achievements presented at top-tier international academic conferences, successfully implementing automatic conversion technology for each feature with high completeness.
Since 2023, the research team has consistently published papers in CACM every year, establishing themselves as global leading researchers who consistently solve important and challenging problems worldwide.
This paper was published in CACM (Communications of the ACM) on October 24, with Dr. Jaemin Hong (Postdoctoral Research Fellow at KAIST Information and Electronics Research Institute) as the first author. ※Paper Title: Automatically Translating C to Rust, DOI: https://doi.org/10.1145/3737696
Dr. Jaemin Hong stated, "The conversion technology we developed is an original technology based on programming language theory, and its biggest strength is that we can logically prove the 'correctness' of the conversion." He added, "While most research relies on Large Language Models (LLMs), our technology can mathematically guarantee the correctness of the conversion."
Dr. Hong is scheduled to be appointed as an Assistant Professor in the Computer Science Department at UNIST starting in March 2025.
Furthermore, Professor Ryu's research team has four papers accepted for presentation at ASE 2025, the highest-authority conference in software engineering, including C→Rust conversion technology.
These papers, in addition to automatic conversion technology, cover various cutting-edge software engineering fields and are receiving high international acclaim. They include: technology to verify whether quantum computer programs operate correctly, 'WEST' technology that automatically checks the correctness of WebAssembly programs (technology for fast and efficient program execution on the web) and creates tests for them, and technology that automatically simplifies complex WebAssembly code to quickly find errors. Among these, the WEST paper received the Distinguished Paper Award.

AI Nüshu Wins International Award
< (From left) Dr. Yuqian Sun, Professor Chang-Hee Lee of the Department of Industrial Design, and Ali Asadipour, Director of CSRC at the Royal College of Art >
'Nüshu (女書)' is the world's only women's script, a unique writing system created autonomously by women in Hunan Province, China, starting around the 19th century. These women, excluded from Hanzi education, used it to record their lives and communicate with each other. A research team from KAIST participated in the 'AI Nüshu (女书)' project, which combines the script's significance (creation amidst oppression, female solidarity, linguistic experimentation) with modern technology, winning a prestigious international award often called the 'Academy Award of the media art world.'
KAIST announced on the 10th that the 'AI Nüshu' project, jointly conducted by Professor Chang-Hee Lee's research team from the Department of Industrial Design and Ali Asadipour, Director of the Computer Science Research Center at the Royal College of Art (RCA), was selected for the Honorary Mention in the Digital Humanity category at the 'Prix Ars Electronica 2025,' the world's highest-level media art festival.
< Installation image of 'AI Nüshu' >
The 'Prix Ars Electronica,' known as the 'Academy Award of the media art world,' is the premier international media art competition held annually in Linz, Austria. This competition, which discovers innovative works spanning the boundaries of art and science, saw 3,987 submissions from 98 countries this year, with only two works receiving the honor in the Digital Humanity category.
The award-winning work, 'AI Nüshu (女书),' is based on 'Nüshu,' the world's only women's script created by Chinese women who were excluded from literacy education to record and communicate their lives.
The KAIST research team and collaborators combined this script with Computational Linguistics to create an installation that visitors can directly experience.
The artificial intelligence within the artwork learns the communication methods of pre-modern Chinese women and generates its own new language. This is regarded as a symbol of resistance against the patriarchal order and a feminist endeavor that moves beyond Western-centric views on language.
< Example of the same sentence expressed in English, Chinese, Nüshu, and AI Nüshu >
It also received high praise for artistically presenting the possibility of machines creating new languages, going beyond the preconception that 'only humans create language.'
Dr. Yuqian Sun of the Royal College of Art expressed her feelings, saying, "Although there were many difficulties in my life and research process, I feel great reward and emotion through this award."
Professor Chang-Hee Lee of the KAIST Department of Industrial Design stated, "It is very meaningful that this contemplative art, born from the intersection of history, humanities, art, and technology, has led to such a globally prestigious award."

KAIST–Princeton University Officially Launch “Net-Zero Korea” to Address Climate Crisis
KAIST (President Kwang Hyung Lee) announced on the 27th of August that a research team led by Professor Hae-Won Jeon of the Graduate School of Green Growth and Sustainable Development has signed a memorandum of understanding (MOU) with the Andlinger Center for Energy and the Environment at Princeton University in the United States to promote joint research on carbon neutrality, officially launching the Net-Zero Korea (NZK) project. This project was unveiled at the World Climate Industry EXPO (WCE) held in BEXCO, Busan, and will begin with seed funding from Google.
The NZK project aims, in the short term, to accelerate the transition of Korea’s energy and industrial sectors toward carbon neutrality, and in the mid- to long term, to strengthen Korea’s energy system modeling capabilities for policy formulation and implementation. Energy system modeling plays a critical role in studying the transition to clean energy and carbon neutrality.
In particular, this research plans to apply Princeton’s leading modeling methodologies from the Net-Zero America project—published in 2021 and widely recognized—to the Korean context by integrating them with KAIST’s integrated assessment modeling research.
The Net-Zero Korea project will be supported by funding from Google, KAIST, and Princeton University. This research is characterized by its detailed analysis of a wide range of factors, from regional land-use changes to job creation, and by concretely visualizing the resulting transformations in energy and industrial systems. It will also be conducted through an international collaborative network while reflecting Korea’s specific conditions. In particular, KAIST will develop an optimization-based open-source energy and industrial system model that integrates the effects of international trade, thereby contributing to global academia and policy research.
Therefore, the core of this modeling research is to apply to Korea the precise analysis and realistic approach that drew attention in Net-Zero America. Through this, it will be possible to visualize changes in the energy and industrial systems at high spatial, temporal, sectoral, and technological resolution, and to comprehensively analyze various factors such as regional land-use changes, capital investment requirements, job creation, and health impacts from air pollution. This will provide stakeholders with practical and reliable information.
In addition, the KAIST research team will collaborate with Princeton researchers, who have conducted national-scale decarbonization modeling studies with major research institutions in Australia, Brazil, China, India, Poland, and others, leveraging a global research network for joint studies.
Building on its experience in developing globally recognized integrated assessment models (IAM) tailored to Korea, KAIST will lead a new initiative to integrate international trade impacts into optimization-based open-source energy and industrial system models. This effort seeks to overcome the limitations of existing national energy modeling by reflecting the particularity of Korea, where trade plays a vital role across the economy.
Professor Wei Peng, Princeton’s principal investigator, said: “Through collaboration with KAIST’s world-class experts in integrated assessment modeling, we will be able to build new research that combines the strengths of macro-energy models and integrated assessment models, thereby developing capabilities applicable to many countries where trade plays a crucial role in the economy, such as Korea.”
Antonia Gawel, Director of Partnerships at Google, stated: “We are very pleased to support this meaningful research being conducted by KAIST and Princeton University in Korea. It will greatly help Google achieve our goal of net-zero emissions across our supply chain by 2030.”
Professor Haewon McJeon of KAIST commented: “Through joint research with Princeton University, which has been leading net-zero studies, we expect to provide science-based evidence to support Korea’s achievement of carbon neutrality and sustainable energy.”
President Kwang Hyung Lee of KAIST remarked: “It is deeply meaningful that KAIST, as Korea’s representative research institution, joins hands with Princeton University, a leading institution in the United States, to jointly build a science-based policy support system for responding to the climate crisis. This collaboration will contribute not only to achieving carbon neutrality in Korean society but also to the global response to the climate crisis.”

A team led by Professor Hyunjoon Park from the Department of Industrial Design won the ‘Best of the Best’ award at the 2025 Red Dot Design Awards, one of the world's top three design awards, for their 'Angel Robotics WSF1 VISION Concept.'
The design for the next-generation wearable robot for people with paraplegia successfully implements functionality, aesthetics, and social inclusion. This latest achievement follows the team's iF Design Award win for the WalkON Suit F1 prototype, which also won a gold medal at the Cybathlon last year. This marks consecutive wins at top-tier international design awards.
KAIST (President Kwang-hyung Lee) announced on the 8th of August that Move Lab, a research team led by Professor Hyunjoon Park from the Department of Industrial Design, won the 'Best of the Best' award in the Design Concept-Professional category at the prestigious '2025 Red Dot Design Awards' for their next-generation wearable robot design, the ‘Angel Robotics WSF1 VISION Concept.’
The German 'Red Dot Design Awards' is one of the world's most well-known design competitions. It is considered one of the world's top three design awards along with Germany’s iF Design Awards and America’s IDEA. The ‘Best of the Best’ award is given to the best design in a category and is awarded only to a very select few of the top designs (within the top 1%) among all Red Dot Award winners.
Professor Hyunjoon Park’s team was honored with the ‘Best of the Best’ award for a user-friendly follow-up development of the ‘WalkON Suit F1 prototype,’ which won a gold medal at the 2024 Cybathlon and an iF Design Award in 2025.

This award-winning design is the result of industry-academic cooperation with Angel Robotics Inc., founded by Professor Kyoungchul Kong from the KAIST Department of Mechanical Engineering. It is a concept design that proposes a next-generation wearable robot (an ultra-personal mobility device) that can be used by people with paraplegia in their daily lives.
The research team focused on transforming Angel Robotics Inc.'s advanced engineering platform into an intuitive and emotional, user-centric experience, implementing a design solution that simultaneously possesses functionality, aesthetics, and social inclusion.
<Figure 2. WSF1 Vision Concept Full Exterior (Front View)>
The WSF1 VISION Concept includes innovative features implemented in Professor Kyoungchul Kong’s Exo Lab, such as:
An autonomous access function where the robot finds the user on its own.
A front-loading mechanism designed for the user to put it on alone while seated.
Multi-directional walking functionality realized through 12 powerful torque actuators and the latest control algorithms.
AI vision technology, along with a multi-visual display system that provides navigation and omnidirectional vision.
This provides users with a safer and more convenient mobility experience.
The strong yet elegant silhouette was achieved through a design process that pursued perfection in proportion, surfaces, and details not seen in existing wearable robots. In particular, the fabric cover that wraps around the entire thigh from the robot's hip joint is a stylish element that respects the wearer's self-esteem and individuality, like fashionable athletic wear. It also acts as a device for the wearer to psychologically feel safe in interacting with the robot and blending in with the general public. This presents a new aesthetic for wearable robots where function and form are harmonized.

KAIST Professor Hyunjoon Park said of the award, "We are focusing on using technology, aesthetics, and human-centered innovation to present advanced technical solutions as easy, enjoyable, and cool experiences for users. Based on Angel Robotics Inc.'s vision of 'recreating human ability with technology,' the WSF1 VISION Concept aimed to break away from the traditional framework of wearable robots and deliver a design experience that adds dignity, independence, and new style to the user's life."

'Acoustic separation and classification technology' is a next-generation artificial intelligence (AI) core technology that enables the early detection of abnormal sounds in areas such as drones, fault detection of factory pipelines, and border surveillance systems, or allows for the separation and editing of spatial audio by sound source when producing AR/VR content.
On the 11th of July, a research team led by Professor Jung-woo Choi of KAIST's Department of Electrical and Electronic Engineering won first place in the 'Spatial Semantic Segmentation of Sound Scenes' task of the 'DCASE2025 Challenge,' the world's most prestigious acoustic detection and analysis competition.
This year’s challenge featured 86 teams competing across six tasks. In this competition, the KAIST research team achieved the best performance in their first-ever participation to Task 4. Professor Jung-woo Choi’s research team consisted of Dr. Dong-heon, Lee, Ph.D. candidate Young-hoo Kwon, and M.S. candidate Do-hwan Kim.
Task 4 titled 'Spatial Semantic Segmentation of Sound Scenes' is a highly demanding task requiring the analysis of spatial information in multi-channel audio signals with overlapping sound sources. The goal was to separate individual sounds and classify them into 18 predefined categories. The research team plans to present their technology at the DCASE workshop in Barcelona this October.
<Figure 1. Example of an acoustic scene with multiple mixed sounds>
Early this year, Dr. Dong-heon Lee developed a state-of-the-art sound source separation AI that combines Transformer and Mamba architectures. During the competition, centered around researcher Young-hoo Kwon, they completed a ‘chain-of-inference architecture' AI model that performs sound source separation and classification again, using the waveforms and types of the initially separated sound sources as clues. This AI model is inspired by human’s auditory scene analysis mechanism that isolates individual sounds by focusing on incomplete clues such as sound type, rhythm, or direction, when listening to complex sounds.
Through this, the team was the only participant to achieve double-digit performance (11 dB) in 'Class-Aware Signal-to-Distortion Ratio Improvement (CA-SDRi)*,' which is the measure for ranking how well the AI separated and classified sounds, proving their technical excellence.
Class-Aware Signal-to-Distortion Ratio Improvement (CA-SDRi): Measures how much clearer (less distorted) the desired sound is separated and classified compared to the original audio, in dB (decibels). A higher number indicates more accurate and cleaner sound separation.
Prof. Jung-woo Choi remarked, "The research team has showcased world-leading acoustic separation AI models for the past three years, and I am delighted that these results have been officially recognized." He added, "I am proud of every member of the research team for winning first place through focused research, despite the significant increase in difficulty and having only a few weeks for development."
