About

Seulki Lee is an associate professor at the School of Electrical Engineering (EE) and Department of AI Systems (AIS) at Korea Advanced Institute of Science and Technology (KAIST), where he leads Embedded AI Lab. He previously served as an Assistant and Associate Professor at  Ulsan National Institute of Science and Technology (UNIST) from 2021 to 2026. He earned his Ph.D. in Computer Science at the Department of Computer Science, the University of North Carolina at Chapel Hill (UNC), advised by Dr. Shahriar Nirjon. His research aims to build embedded physical AI systems that can sense, learn, reason, plan, adapt, and act across cyber and physical environments under real-world constraints on computation, memory, energy, and connectivity. Prior to starting his Ph.D., he designed sensor system architecture and intelligent sensing algorithms for smartphones at Samsung Electronics. He spent two summers as a research intern at Nokia Bell Labs and Mercedes-Benz Research & Development North America, where he researched machine learning and future transportation systems.
