Career Profile

I am a Ph.D. student at Yonsei University, Korea, studying computer architecture (advisor: Won Woo Ro). My research primarily focuses on enhancing the performance and energy efficiency of parallel processing units (e.g., GPUs and Domain-Specific Accelerators) by innovating their computing models. I believe such devices can help humanity expand its full capabilities, but it requires making their computing model more intelligent. Driven by this vision, I am enthusiastic about dedicating my talents and passion to empowering humanity to be more creative, intelligent, efficient, and fulfilled.

I am seeking a job/postdoctoral program in the United States with visa support (my expected graduation date is Aug 2024)
