Research:
Broadly speaking, my research area is theoretical computer science. More specifically, my current research interests are in distributed algorithms, randomization, and approximation algorithms and combinatorial optimization. I am part of the Algorithms Research Group at Iowa. I have also become interested in models and algorithms for contact networks, diffusion of disease through contact networks, and the design of effective policies to mitigate disease spread. I am part of the Computational Epidemiology Group at Iowa.

Openings for Fall 2019:
I am looking for PhD students in distributed algorithms and PhD students and a post-doctoral fellow in computational epidemiology. Read on if you are interested...
