I am currently a tenure track researcher at CWI in the Networks & Optimization group. Previously, I was a Simons Postdoctoral Fellow for 2 years at the Courant Institute of Mathematical Sciences at New York University. I completed my PhD in 2012 within the ACO (Algorithms, Combinatorics, and Optimization) program at Georgia Tech under Santosh Vempala (Professor of Computer Science).


I am jointly organizing a workshop on Discrepancy Theory and Integer Programming, June 11-15 at CWI. Space is very limited so register early!
