Caleb Stanford

Me in 2021

I am on the academic job market this year!

I am a PhD student in computer science at the University of Pennsylvania since Fall 2016, advised by Rajeev Alur. I am expected to graduate in May 2022. You can also view my CV online.


Research areas

My research lies in programming languages and systems. In particular, I am interested in programming languages and formal methods applications to data processing, distributed systems, and networks. I am affiliated with the Penn PL Club:
