Professor: Boris Fine
Oleg graduated from the Moscow Institute of Physics and Technology in 2006, and received Candidate of Sciences (PhD) degree from the Institute for Theoretical and Experimental Physics in 2009. His early research activities, including his postgraduate studies, were devoted to the theoretical physics of elementary particles and fields and astroparticle physics. In 2012, he moved to the Lancaster University, UK, to work as a Senior Research Associate on the far-from-equilibrium quantum dynamics of an impurity particle in a one-dimensional quantum fluid. In 2014, he moved back to Moscow to work for the Russian Quantum Center as a member of the Many-body Theory Group. In 2016, he got involved in a project aimed at the development of the Quantum Key Distribution system, a joint venture of a consortium of companies and research centers, including the Russian Quantum Center, DePhAn LLC and Steklov Mathematical Institute. In 2017 he moved to Skoltech to work on quantum many-body theory. In June 2017 his project “Quantum adiabaticity in many-body systems” was supported by a 3-year grant of the Russian Science Foundation. In October 2018 he acquired a 2-year grant from the Russian Foundation for Basic Research to develop a project “Far-from-equilibrium dynamics in quantum impurity models”.
