As of February 2017 I am working at Uppsala University.
For the moment, this web page will continue to serve as my personal web page.

 

I am a former Ph.D. student in the Algorithms, Combinatorics and Optimization (ACO) program. My research advisor was Alan Frieze. My research interests are random graphs, randomized algorithms and probabilistic combinatorics.
