Egor Kosov studied at the Faculty of Mechanics and Mathematics, Lomonosov Moscow State University, where he obtained his PhD with the thesis "Polynomial images and shifts of measures on linear spaces". Before joining the CRM, he held positions as an assistant at the Department of Theory of Functions and Functional Analysis at the Lomonosov Moscow State University, as an assistant professor at the Faculty of Computer Science at the HSE University, and as a senior research fellow at the Department of Function Theory at the Steklov Mathematical Institute. He has worked on problems related to the discretization of integral norms, and Nikolskii-Besov regularity properties of distributions.

He joined the Harmonic Analysis and Approximation Theory group to work with Sergey Tikhonov as a postdoctoral researcher.
