I obtained my first Ph.D. in June 2012 under the supervision of Prof. S. Lakaev from Samarkand State University, Uzbekistan, in Mathematical Physics, and my second Ph.D. in 2017 under the supervision of Prof. G. Bellettini from Scuola Internazionale Superiore di Studi Avanzati (SISSA) and International Centre for Theoretical Physics (ICTP), Trieste, Italy, in Mathematical Analysis.

Since October 2017 I am Postdoctoral Associate in the Faculty of Mathematics of University of Vienna in the research group Variational Methods and Applications of Paolo Piovano .

Currently, I am a Lise-Meitner Grantee of the Austrian Science Fund (FWF). My CV is here. here.

My general research interests are in calculus of variations and geometric measure theory (CVGMT) and spectral theory (ST). More precisely:

• existence and regularity in CVGMT: free boundary problems (with or without elastic energy) including boundary discontinuities such as partitions, internal cracks, wetting, edge delaminations, debonding, brittle fractures; (anisotropic and crystalline) minimal surfaces; capillarity problems; area functional; higher order problems related to perimeter (such as Willmore problem);
• evolution in CVGMT: geometric evolution problems such as (anisotropic and crystalline) mean curvature flow, mean curvature flow of partitions; quasitatic evolution problems of elastic materials; nonlocal evolution problems;
• discrete Schrodinger operators in ST: coupling constant threshold phenomenon; multiparticle lattice systems, location of essential spectrum, existence of discrete spectrum, Efimov effect; asymptotics of eigenvalues.
