Short CV.

Program on Semidefinite and Matrix Methods for Optimization and Communication, IMS.  Jan-Feb 2016.

I have been an organizer (with Troy Lee, Dirk Oliver Theis, Rekha R. Thomas) of the Dagstuhl Workshop

Limitations of convex programming: lower bounds on extended formulations and factorization ranks Feb. 15-20, 2015,

see the report here.

The previous workshop Communication complexity, linear optimization, and lower bounds for the nonnegative rank

we held in  February 2013, see the report here or here.
