Biomedical Electronics Lab

BioMEdical Electronics Lab (BMEEL) is a research lab in the Department of Biomedical Engineering, College of Medicine at Seoul National University (SNU), South Korea. We are committed to working on engineering problems at the intersection of Microelectronics (Sensors, Microfabrication), Biomedical engineering, and Medicine.

We are particularly interested in the following research areas: (1) Advanced Neurotechnology; (2) Biosensors and Wearable Devices; (3) Microelectronics for Biomedical Applications; (4) Machine Learning-based Bio-signal Analysis; (5) Novel electronic devices and applications.

Some of our members are also affiliated with the Advanced Electronic Device Research Group at DGIST EECS (Department of Electrical Engineering and Computer Science), co-advised by Professor Hyuk-Jun Kwon. 

We are also jointly affiliated with the Interdisciplinary Program in Bioengineering (서울대학교 공과대학 협동과정 바이오엔지니어링 전공), College of Engineering, Seoul National University, in charge of Bioelectronics (바이오전자) area. If you are interested in joining us, please look for the admission opportunities through this program.
