Positions: I am assistant professor at the department of computer science in Rutgers University (New Brunswick). Before then I was a PostDoc at TU Berlin, where I was part of the group Combinatorial Algorithms and Graph Optimization (COGA), led by Martin Skutella. I received my Ph.D. from Columbia University (2010-2016), with Cliff Stein as my advisor. I received my undergraduate degree in mathematics from MIT in 2009.
Interests: My research interests are in the design and analysis of algorithms. Specific topics include sublinear algorithms for processing large inputs (e.g. streaming, parallel), dynamic graph algorithms, online algorithms, distributed algorithms, fault-tolerant algorithms, and approximation algorithms.
