Career History and Professional Experience:

$\mathbf{2010}$ - $\mathbf{present}$

$\mathbf{Tech-X Corporation}$

$\mathbf{Boulder, CO}$ -- Principal Research Scientist (2010-)

• Contributing to the development, verification and validation of whole-device integrated modeling FACETS code.

$\mathbf{2006}$ - $\mathbf{2010}$

$\mathbf{Lehigh University}$

$\mathbf{Bethlehem, PA}$ -- Principal Research Scientist (2010) -- Senior Research Scientist(2007-2010) -- Research Scientist(2006-2007)

• Contributed to the SciDAC Framework Application for Core-Edge Transport Simulations (FACETS) project by developing an interface to anomalous and neoclassical transport modules and codes.
• Developing computational simulations for the SciDAC Center for Plasma Edge Simulation (CPES). Implemented the TEQ equilibrium solver in the gyro-kinetic code XGC. Applied gyro-kinetic code XGC, extended MHD code NIMROD, and ideal MHD stability code ELITE to the multi-scale analysis of edge-localized modes in tokamaks.
• Working with graduate and undergradute students;
• Contributing to the development of a new interface to anomalous transport reduced models for the Framework for Modernization and Componentization of Fusion Modules (FMCFM). This project also includes parallelization of GLF23 transport model.
• Involved in the accretion disk modeling for the Center for Magnetic Self-Organization.

$\mathbf{2004}$ - $\mathbf{2006}$

$\mathbf{SAIC}$

$\mathbf{San Diego, CA}$ -- Research Scientist

• Contributed to the development of the extended MHD code NIMROD. Enhanced the code by including the hyper- and gyro-viscosity terms. The NIMROD code is a fully implicit code that employs finite elements in the poloidal plane and pseudo-spectral method in the toroidal plane. The NIMROD code is optimized for massively parallel computers using Message Parsing Interface.
• Applied the NIMROD code to the modeling of ELM dynamics. This project was a part of the Department of Energy theory milestone for 2005/06.

$\mathbf{1999}$ - $\mathbf{2004}$

$\mathbf{Lehigh University}$

$\mathbf{Bethlehem, PA}$ -- Research Scientist

• Contributed to the National Transport Code Collaboration project. The objective of the NTCC project was to integrate major predictive transport models (IFS/PPPL, GLF23, and the Multi-Mode Model) and to create a fully web-invocable interface to the International Profile Database and to the predictive transport models. The basic elements of these projects were object-oriented programming with C++, Java, and Python, as well as client-server through an object-oriented protocol, CORBA/IDL interface for data and physics servers.

$\mathbf{1995}$ - $\mathbf{1999}$

$\mathbf{Institute for Nuclear Research}$

$\mathbf{Kiev, Ukraine}$ -- Scientific Researcher $\mathbf{1996}$ - $\mathbf{1999}$
