About Me

I am a Ph.D. student at VIU Lab, Johns Hopkins University. I obtained my bachelor's degree from Dept. of Computer Science, University of Illinois at Urbana-Champaign in May, 2020. During my three years at UIUC, I have fortunately conducted research at Image Formation and Processing Group. I have spent some fun time interning at Microsoft (2021) and Horizon Robotics (2019).
