Semyon Dyatlov is Associate Professor of Mathematics, effective July 2018. In July 2019 he recevied tenure. He joined the mathematics faculty as Assistant Professor in January, 2016. Semyon received his Ph.D. from University of California, Berkeley in 2013, under the guidance of Maciej Zworski. In 2013, Dyatlov received 5-year Clay Research Fellowship. In 2017, he received a Sloan Research Fellowship. In 2018, he received both the Early Career Award of the International Association of Mathematical Physics, and the NSF CAREER Development Award. In July 2020, it was announced that Dyatlov, jointly with Jonathan Kelner and CLE Moore Instructor Pei-Ken Hung, received the 2020 MIT Teaching with Digital Technology Award, for enhancing on-campus and remote teaching.
Semyon uses the methods of microlocal analysis to study problems in scattering theory, in particular questions regarding scattering resonances. The two principal applications of his work concern decay of waves on black hole spacetimes (where resonances are known as quasi-normal modes) and decay of correlations for Anosov and Axiom A flows (and the corresponding Pollicott-Ruelle resonances).
