Hyungjun Yoon is a Ph.D. candidate in the Mobile Intelligence and Interaction Lab (MIIL) at KAIST, advised by Prof. Sung-Ju Lee. His research focuses on foundation models and large language models (LLMs) for mobile sensing and healthcare applications. He was a research intern at Microsoft Research mentored by Prof. Lili Qiu, a research intern at Nokia Bell Labs hosted by Prof. Fahim Kawsar, and a visiting researcher at NTU advised by Prof. Mo Li. His recent work explores multi-agent collaboration for multimodal sensing, foundation models for earphone-based ExG signals, and grounding LLMs with sensor data. His broader goal is to develop scalable and generalizable AI systems that bridge foundation models and real-world health sensing applications.
