Alex Cohen

Alex Cohen will receive his PhD from the Massachusetts Institute of Technology in 2025, under the supervision of Larry Guth.

Cohen is a broad and thoughtful researcher who has made innovative contributions to harmonic analysis, combinatorics, and microlocal analysis.  His work on the higher dimensional fractal uncertainty principle is of particular note. It has important applications to the field of quantum chaos, generalizing the celebrated work of Bourgain and Dyatlov to arbitrary dimensions. In this context, he also developed a higher-dimensional version of the Beurling-Malliavin theorem, a deep theorem about one complex variable from the early 1960s.

Alex Cohen has been appointed as a Clay Research Fellow for five years beginning 1 July 2025. He will be based initially at New York University.
