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 also have spent some fun time interning at Adobe (2022), Microsoft (2021) and Horizon Robotics (2019).
My research helps people produce creative and artistic visual effects with ease (Neural Rendering), see a clear world through digital lens (Super-Resolution), and improve personalized experiences with protected privacy (Federated Learning).
