I am on the lookout for mathematically strong candidates interested in pursuing a PhD in optimization and algorithms. If you are interested, contact me directly.

I am an Associate Professor in the Department of Econometrics and Operations Research at Vrije Universiteit Amsterdam, where I am part of the Operations Research group. I am also affiliated with CWI. I have been awarded a VIDI grant, a TOP grant, and a VENI grant (now completed) by the NWO (the Dutch Organization for Scientific Research).

Before this, I spent three years an Applied Mathematics Instructor at MIT, under the mentorship of Michel Goemans. I was a PhD student in the Department of Mathematics and Statistics at McGill University, in Montreal, Canada, advised by Bruce Shepherd and Adrian Vetta. My undergraduate education was at the University of Cape Town, South Africa.

I work primarily in combinatorial optimization, with excursions into game theory and probability. See the research and publications sections of this homepage for more.
