Song Min Kim is an Associate Professor in the School of Electrical Engineering at KAIST, leading the SMILE (SMart and MobILE) lab. He currently focuses on co-designing hardware and software for mobile systems and battery-free devices towards massive communication, ultra-precision sensing, and intelligent interactions. Also, he had been putting effort into developing a new area of cross-technology communication (CTC) from his early work in MobiCom '15. He received the best paper awards in ACM MobiSys 2024, 2022, and IEEE ICDCS 2018. He serves/served on the editorial boards of IEEE/ACM ToN, ACM TOSN, ACM TIOT, and TPC for MobiCom, SenSys, and NSDI. Before joining KAIST, he was with the Department of Computer Science at George Mason University.
