My main research interests are in theory of complex systems and, therefore, they are in the interplay of mathematical physics, functional analysis, PDE, and probability theory. In particular, I have worked on problems dealing with infinite-dimensional analysis, applications of methods of functional analysis and probability theory to mathematical physics, Gibbs measures, point processes, stochastic dynamics and scaling limits, mathematical biology. Currently, I am actively working in the study of non-local evolution equations arising as (mesoscopics) limits for dynamics of the considered complex systems.
