About Me

I am a Ph.D. student in Crossroads System Exploration Lab (XSEL), School of Electrical and Computer Engineering, Purdue University. My advisor is Prof. Felix Xiaozhu Lin. My research interest focuses on building software systems for large-scale video analytics on a wide range of deep learning and computer vision workloads.

My hobbies include playing soccer, playing cello, and watching movies.
