About me

I am a graduating PhD student (2025 Summer) in Computer Science department at Columbia University, co-advised by Prof.Asaf Cidon and Prof.Junfeng Yang.

I received my B.S. from the University of Wisconsin-Madison in Dec 2019. At Madison, I was advised by Prof.Shivaram Venkataraman.

My research focuses in the intersection of Machine Learning, Systems and Security. I am actively exploring potential start-up ideas. Please contact me if you want to collaborate or just for a fun chat.
