About Me

I am a Staff Engineer at Samsung Electronics, specializing in the development of Processing-In-Memory (PIM) solutions. My academic background includes a Ph.D. in Electrical Engineering from KAIST, under the direction of Professor Minsoo Rhu, as well as a Master of Science from POSTECH, supervised by Professor Hanjun Kim, and a Bachelor of Science from POSTECH. My research expertise centers on system-level support for PIM architectures.
