**Alexander Razborov**graduated from the Steklov Mathematical Institute in 1987 under the supervision of Sergei I. Adian. The title of his dissertation was "On systems of equations in a free group" (in Russian). He is interested in theoretical computer science (especially complexity theory of any kind) and mathematics, more often discrete than not.

**Sergey Yekhanin**obtained his doctoral degree from MIT in 2007 under the supervision of Madhu Sudan. Sergey is currently a postdoc at the School of Mathematics of the Institute for Advanced Study. His research interests are in computational complexity theory, cryptography, and the theory of error-correcting codes.
