Boundary homogenization for PDE in domains with microinhomogeneous structure. There were formulated and proved homogenization Theorems for boundary value problems with rapidly changing type of boundary conditions with periodic and nonperiodic boundary conditions. Also there were obtained the estimates of deviation of solutions of initial problem from solutions of homogenizaed problem. Vibration of thin plates, rods and junctions. Vibration of thin nonsymmetric plates with rough surface and other singular constructions were described. Weighted Korn type inequality for such domains were proved. Homogenization of random structures. We gave new definition of domains with random structure and proved homogenization theroems. Domains with oscillating boundary. We studied the behavior of bodies with the oscillation of external boundary and internal perforation. Also there were proved homogenization theorems and were constructed leading terms of the asymptotic expansion of solutions with respect to the small parameter characterized the microinhomogenity.Singular Measures and homogenization. We introduced new approach to homogenization problems in domains with thin and infinitisimally thin elements. We define the Sobolev function-spaces, proved the embedding theorems and Weyl-type theorems. Also we proved homogenization theorems for such structures.


Graduated from Faculty of Mathematics and Mechanics of M. V. Lomonosov Moscow State University (MSU) in 1988 (department of differential equations). Ph.D. thesis was defended in 1992 (scientific advisor — academitioan professor Olga Oleinik). Doctor of Mathematics (habilitation) in 2007. A list of my works contains more than 110 titles (including two monographs). Since 1994 I have led the research seminar at MSU on homogenization theory. I was an invited professor in few universities (France, Italy, Japan, Norway, Spain, USA). I am a scientific advisor of graduate students.

First place in Young Scientists Competition, 1988, Moscow State University. I won the competition in Moscow State University and became the International Research Scholar — MUSSIA (Indiana University, Bloomington, 1990.) Prize winner of the french PRO MATHEMATICA grants for Young Scientists (1992–1994, 1996–1998). I gave more then 10 plenary and invited lectures at international conferences and congresses.
