In the AHHA lab, he is currently working on research problems related to body area networks and RFID sensing.

Hee-Tae Jung

PhD Candidate

Hee-Tae Jung is the last year PhD student in the AHHA lab. He received his BS from Yonsei University and his MS from Stanford University, both in Computer Science. His research goal is to maximize the overall quality of the rehabilitation service through technology-assisted therapies. Towards that end, he specifically focuses on three paths. 1) He investigates various ways to use artificial intelligence to monitor the impairment level and the optimally intervene. 2) He conducts clinical studies to understand the therapeutic benefit of technology-assisted therapies in routine clinical settings. 3) In a human-computer interaction perspective, he attempts to analyze the pros and cons of technology-assisted therapies and to understand the room to advance the contemporary state-of-the-art rehabilitation technology.
