Haoran Zhang   张浩然

I am a fourth year Ph.D. student in the Department of Computer and Information Science at Penn, co-advised by Vincent Liu and Sebastian Angel. I also have had the fortune to work with Rajeev Alur and Shuai Mu. Before Penn, I obtained B.E. Degree in Computer Science from Tsinghua University.

My research interests include distributed systems, databases and networking, with a focus on serverless computing.

I’m allergic to cats, but the advent of CaaS (Cat-as-a-Service) has made cloud petting possible. 瓜皮(➔) is my favorite.

My Email is haorz at seas dot upenn dot edu. You can also find me on Github, Linkedin, Keybase, Mastodon.
