Junhyeok Park

I am currently a researcher (pre-doctoral) at Electronics and Telecommunications Research Institute (ETRI). I received my Master’s degree in Electrical and Computer Engineering from Sungkyunkwan University, under the supervision of Prof. Seokin Hong.

My research interests include designing efficient heterogeneous computing platforms that integrate multiple XPUs (CPUs, GPUs, and NPUs).

I will begin my Ph.D. at Georgia Tech in Fall 2026.
