This award is made as part of the FY 2013 Mathematical Sciences Postdoctoral Research Fellowships Program. Each of the fellowships supports a research and training project at a host institution in the mathematical sciences, including applications to other disciplines, under the mentorship of a sponsoring scientist. The title of the project for this fellowship to Robin Tucker-Drob is "Global Ergodic Theory and Representation Theory of Groups." The host institution for the fellowship is Rutgers University, and the sponsoring scientist is Dr. Simon Thomas.
