Juneseo Chang

I am an undergraduate student majoring Computer Science and Engineering at Seoul National University. I was an undergraduate research intern at SCALable Computer Architecture Laboratory, Seoul National University, led by Prof. Jung Ho Ahn. My research interests lie at the intersection of Computer Architecture and Operating Systems.

I will be joining Stanford University EE Ph.D. student starting Fall 2026!
