Hyeonsu Bang


I am currently pursuing a Ph.D. in the Department of Electrical and Computer Engineering at Sungkyunkwan University (SKKU). I am advised by Jong Hwan Ko in the SKKU IRIS Lab, and I completed my master’s degree in the same lab. My topics of interest include AI processor, on-device AI, and in-memory computing. Outside of studies, my hobbies include running, bodyweight exercise, and card magic.
