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. I build systems for video analytics, which support a wide range of deep learning and computer vision workloads. I am also interested in Linux kernel development.

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