I am Jaehyuck Lim, a Ph.D. student at the KAIST Cho Chun Shik Graduate School of Mobility, TUPA Lab (Advisor: Prof. Inhi Kim). Majoring in Transportation Engineering, I primarily conduct research on humanoid-based sim-to-real transfer and human factor-centric traffic safety using immersive simulators.

Research

My research spans robot learning and traffic safety, connected by simulation as a common tool. (← Add a short overview paragraph here.)

Simulator-based Traffic Safety

I build virtual road, traffic, weather, and vehicle environments to analyze driver behavior and safety experimentally, without exposing drivers to real-world danger. This approach makes it possible to recreate hazardous situations without actual crashes, and to present the exact same scenario repeatedly to every participant, so that comparisons between conditions are clear. It also allows road facilities or in-vehicle systems that have not yet been deployed on real roads to be evaluated in advance. As a result, this line of research is well suited to the early-stage design of new traffic-safety technologies and to the exploration of risk factors. The main topics I work on are as follows.

Generative AI Leading Talent Cultivation Program

생성형 AI 선도 인재 양성 프로그램

2026 – 2029 LABIITP

Formally titled Development of Industry-Specific Physical AI Foundation Models and Cultivation of Next-Generation Convergence Talent, this IITP program runs from April 2026 to December 2029. Lotte Innovate leads the consortium, with KAIST, Yonsei University, and Inha University as joint research organizations, and Lotte affiliates — Korea Seven, Lotte E&C, Lotte Global Logistics, Lotte World, and others — serving as the field-demonstration and validation ground.

The core idea is to extend generative AI beyond the language and vision digital domain into the physical world — perception, reasoning, planning, action, and operation. The goal is to build an industry-specialized Physical AI foundation model while simultaneously training convergence-type talent, then dispatching and hiring top students into the affiliates so that research and industry feed each other.

Development of Virtual Environment and Demonstration Technology for Automated Driving based on Metaverse

메타버스 기반 자율주행 가상환경 및 실증 기술 개발

2023 – 2027 LABMOLIT

Part of MOLIT's autonomous-driving innovation program, this project (April 2023 – December 2027) builds a multi-purpose, variably extensible virtual test environment for Lv.4/4+ automated driving that serves three uses at once: training AV AI, verifying AV performance, and evaluating and certifying AVs. KATRI, the Korea Automobile Testing & Research Institute, leads the consortium; KAIST joins as a co-research organization alongside MORAI, Nota, NAVER LABS, and other industry partners.

The problem it addresses is that simulation today is built for developers, not for the people who have to certify a vehicle: scenarios are limited, formats are proprietary, and living-lab demonstration cannot be rehearsed safely. The target is a standardized, modular, open platform running large-scale parallel tests on hybrid cloud, with Korean road content and living-lab data behind it.
