I am an Assistant Professor at the GIST Graduate School of Advanced Semiconductor Engineering [COSMIC Lab].

My research interests are in computer architecture, with a focus on hardware/software co-design for efficient AI systems, including neural network accelerators, on-device AI, processing-near-memory, and GPU microarchitecture.

I received my Integrated M.S./Ph.D. in Electrical and Electronic Engineering (Computer Architecture) from Yonsei University, advised by Prof. Won Woo Ro [Lab]. Prior to joining GIST, I worked as a System Architect at Samsung Electronics.

I am looking for motivated M.S./Ph.D. students, postdocs, and interns. If you are interested, please see the COSMIC Lab website for how to apply.
