Shreyas Pai

There should be a picture of me here...

I am a postdoc in the Theory group at Aalto University hosted by Prof. Jara Uitto.
I received my PhD in Computer Science at The University of Iowa under the supervision of Prof. Sriram Pemmaraju in Spring 2021.

My research interests generally lie in Theoretical Computer Science, more specifically in Distributed Algorithms, Communication Complexity, and Combinatorial Optimization.

During my PhD, I was a research assistant in the Computational Epidemiology Group where I worked on understanding and modeling the spread of Hospital Acquired Infections (see here for more information).

Here is my CV. And these are links to my arXiv and dblp pages.
