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