I am a Ph.D. student working on systems at Berkeley NetSys. My current research interests are cost-efficient machine learning and memory systems.

I am graduating soon and open to work! I am interested in opportunities in computer systems research and engineering.

My Ph.D. study is being supported by Korean Foundation for Advanced Study (KFAS).

Before I came to Berkeley, I earned my MS from Seoul National University, under the guidance of Jae W. Lee, and BS from Postech 
