About Me

Before joining FSU, I was a Postdoctoral Scholar at the NSF AI-EDGE Institute at The Ohio State University (OSU), where I had the privilege of working under the joint guidance of Prof. Ness Shroff, Prof. Eylem Ekici, and Prof. Kannan Srinivasan. I completed my Ph.D. at the University of Maryland, Baltimore County (UMBC), where I was mentored by Prof. Ting Zhu (now at OSU).
