GeezerVison

I’m a final year PhD student at Georgia Tech studying Computer Science. Currently, I’m luckily advised by Prof. Bo Zhu. Previsouly, I was fortune to working with Prof. Changxi Zheng and Ziwei Zhu at Columbia University during my Master’s Degree and Prof. Adriana Schulz and Ben Jones at GRAIL during my undergrad at Paul G. Allen School at University of Washington.

Here is my CV.
