Heehyun (Bucky) Park

Hi, I am Heehyun (Bucky) Park, a 6th-year Ph.D. candidate in Computer Science at Penn State University, University Park, working with Dr. Antonio Blanca. I did my Master's degree in Math with Dr. Izabella Stuhl along with my Ph.D. degree in Computer Science.

My current research interests are Markov chains, spin systems, applied probability and topological data analysis.

I am passionate about everything about mathematics and football (not American football).
