I am a second-year post-doctoral member at the Institute for
Advanced Study. I graduated from
the Weizmann
Institute of Science in July
2007, under the supervision of Prof.
Gideon Schechtman.
My main research interests lie in the various aspects of Asymptotic Convex Geometric Analysis. This is the study of geometric structures satisfying appropriate convexity conditions from a geometric and analytic point of view, with an emphasis on the asymptotic dependence (or independence) of various parameters on the underlying dimension. Examples of such structures include bounded convex domains in Euclidean space Rn, Banach spaces (possibly infinite dimensional), Riemannian manifolds with non-negative (Ricci) curvature, and other generalizations. Since its conception at the intersection of classical Convex Geometry and the local theory of Banach spaces, the field of Asymptotic Convex Geometric Analysis has been evolving constantly, and has uncovered connections to many other fields, such as Probability Theory, PDE, Riemannian Geometry, Harmonic Analysis, Mathematical Physics, Combinatorics, Graph Theory and Learning Theory.
Some of my related research interests include classical Convex Geometry, the interplay between geometry and spectral properties of Riemannian manifolds, geometry of isoperimetric minimizing surfaces, isoperimetric, functional and concentration inequalities, Geometric Measure Theory, diffusion semi-group and heat-kernel estimates in convex manifolds, optimal transportation for the Monge-Amp`ere equation, distribution of volume in convex bodies, “local theory” of Banach Spaces, convexity in graphs, metric entropy and covering numbers, empirical processes, general phenomena in high dimensions, Radon transforms and Harmonic Analysis on Grassmann manifolds.
