Theory Group

Theory Group

Established: February 3, 1997

We work on fundamental problems in mathematics and theoretical computer science, interact extensively with the academic community and collaborate with other researchers at MSR on challenging applied problems. Among our areas of expertise are probability, algorithms, statistical learning, optimization, algorithmic game theory, error-correcting codes, combinatorics, statistical physics, and fractals. We host an amazing array of researchers in these areas, see below for a list of recent and upcoming visitors.

See the Theory Seminar for a list of upcoming and recent talks (often recorded on video).

The group reports to Chris Meek.

Maximum Overhang, Optimum Reward

By Janie Chang, Writer, Microsoft Research Yuval Peres, principal researcher at Microsoft Research Redmond and manager of the Theory Group, always advocates both healthy skepticism and an open mind when it comes to problem solving. Even so, Peres was pleasantly surprised when a paper he co-authored won the prestigious David P. Robbins Prize from the Mathematical Association of America (MAA) for taking a completely new approach to a problem mathematicians had considered solved for decades.…
