PROFESSIONAL EMPLOYMENT

July 1996 - present time: Research scientist, Department of Physics, State University of New York at Stony Brook, Stony Brook, New York.

Analysis of ultra-small semiconductor devices.

September 1994 - July 1996: Postdoctoral research associate, Department of Physics, University of California at Santa Barbara, Santa Barbara, California. Scientific adviser - Prof. W. Kohn

Conducted research on strongly correlated systems, metal-insulator transition, weak localization, two- dimensional electron gas, non-Fermi liquid behavior, quantum Hall effect, and Coulomb systems.
Developed scaleable parallel program for simulation of GaAs/AlGaAs/InGaAs quantum dot arrays and obtained excellent agreement with the experimental data
Discovered new effects in the behavior of nanoscale semiconductor devices in strong laser fields
Developed new theory for magnetoresistance in AlGaAs/InGaAs heterostructures - first theory to reach an agreement with experiments. Designed highly efficient system for data fitting and analysis and successfully applied it to analysis of recent experimental data collected from many laboratories around the world using our new theory.
Developed novel Monte-Carlo algorithm and wrote highly optimized implementation for Cray supercomputers.

September 1991 - September 1994: Postdoctoral research associate, Department of Physics, University of Utah, Salt Lake City, Utah. Scientific adviser - Prof. A. Efros

Conducted research on quantum Hall effect, magnetotransport and thermodynamics of electron liquids, Coulomb systems, magnetic semiconductors, optics of heterostructures.
Proposed a new model for a wide-channel silicon field-effect transistor (MOSFET) which explained the paradoxical dependence of the resistance on the channel length observed experimentally.
Developed novel theory of tunneling in GaAs/AlGaAs double quantum well structures.
Developed a comprehensive theory of thermodynamics of electron layers in GaAs high-mobility field-effect transistors (FETs).
Developed new theory and designed an algorithm for modeling of arrays of quantum dots in a magnetic field. This was the first case when the entire shape of magnetoresistance curve was correctly calculated
Proposed new theory and processed the experimental results for GaAs and InAs quantum wells, which allowed to identify the main mechanisms of the influence of heterointerfaces on the optical properties of these quantum wells and devices (lasers, diodes) which use them.
Wrote eigensolver for huge sparse matrices and optimized it for Cray supercomputers. Performance far exceeds all similar codes, publicly available or maintained by supercomputer centers.
Created codes for constrained optimization of functions of many (100,000) variables and used them to confirm our theories and get qualitative results explaining experimental puzzles. Designed and optimized Monte-Carlo codes for workstations, vector supercomputers and parallel computers.
Developed parallel integration code with automatic load balancing for distributed memory parallel computers.
Provided computational support for our group

March 1990 - September 1991: Staff scientist, A. F. Ioffe Institute, Leningrad, Russia.

Conducted research on optics and transport in heterostructures and MOSFETs.
Designed "intelligent" variational Monte-Carlo code for simulation of excitonic light modulators on GaAs heterostructures.
Developed theory and algorithm for modeling of electronic and optical properties of SiC.
Calculated the current-voltage characteristics of a FET in a highly non-linear regime in magnetic field.
Developed theory of mobility enhancement in FETs. Wrote modeling and optimization software for semiconductor heterostructure transistors which allows to optimize performance of these devices.
