He focused on the development of new computational approaches for treating large protein systems, with the goal of predicting such proteins’ detailed function from knowledge of their structure. In 2008, Dr. Miloshevsky joined School of Nuclear Engineering at Purdue University, as Research Scientist (2008-2009), Research Assistant Professor (2009-2013), Research Associate Professor (2013-2015), and Associate Professor (2015-2018). Since 2019, he is an Associate Professor in the Department of Mechanical and Nuclear Engineering at Virginia Commonwealth University. Dr. Miloshevsky had the opportunity to work on many multidisciplinary research projects both in laboratory and academia environments. His research area of expertise is Computational Physics with emphasis on the effects of plasma, laser and particle beams on materials, shielding of space radiation, fission SNM sources, atomic and plasma physics, warm dense matter, dusty plasmas, Computational Fluid Dynamics, two-fluid liquid metal-plasma flows, Molecular Dynamics, Monte Carlo, Hartree-Fock and DFT methods, permeation and gating of protein channels and transporters, biophysics of lipid bilayers and membranes.

Warm Dense Matter (WDM)

equilibrium WDM naturally occurring in cores of large planets and rapidly evolving and highly non-equilibrium WDM produced in laboratory by high energy lasers, Z-pinch X-ray sources and nuclear detonations; equations of state, optical, and electrical properties of highly dense (0.1 to 10-fold solid density) and low temperature (1 eV – 10 eV) WDM; development of advanced, quantum-level computational models (Monte Carlo and Molecular Dynamics methods coupled with the Hartree-Fock-Slater - Collisional-Radiative Steady-State model) for predicting the formation, spatiotemporal evolution, physical and electrical properties of WDM

Fusion Plasma-Material Interactions

Melting of metallic plasma facing components, macroscopic melt motion, and melt splashing with droplets due to edge localized modes and plasma disruptions in fusion devices; coupled flow of plasma, vapor, and liquid metal under the effect of an external magnetic field; development and implementation of multi-fluid flow models within OpenFOAM CFD toolkit

PI: Spatiotemporal Evolution of High-Density Surface Plasmas Produced by Prompt X-rays

Defense Thread Reduction Agency

2018-04-22

A high-altitude nuclear burst can radiate 70 to 80 percent of its released energy as X-rays. A major effect of prompt cold X-rays to a few microns of satellite surface materials is surface vaporization, ionization, and generation of high-density blow-off plasma. Solar cells are more susceptible to prompt X-rays, since the large surface area is exposed to radiation and cannot be substantially shielded. Implications of X-ray irradiation of solar cells are potentially quite serious. The surface plasmas can couple the solar cells to each other and to dielectric structures causing them to be destroyed. The objective of the proposed research is to explore the physics mechanisms of prompt cold X-ray absorption by metallic and dielectric materials, formation and expansion phases of produced warm dense plasma (WDP), and its physical and electrical properties. We propose to study the fundamental physics of the formation and spatiotemporal evolution of WDPs using the Monte Carlo (MC) and Molecular Dynamics (MD) methods coupled with the Hartree-Fock-Slater (HFS) - Collisional-Radiative Steady-State (CRSS) model. This basic research covering the science of the creation, time evolution, and physical properties of WDPs generated in the cold X-ray radiation environment will improve our understanding of ways to design more survivable solar arrays for satellites.

PI: Predictive Simulations Of Thermodynamic And Optical Properties Of Warm Dense Matter

Defense Thread Reduction Agency

2011-07-18

The regime of warm dense matter (WDM) corresponds to the phase diagram with densities ranging from 0.1 to 10-fold solid density and temperatures from 1 to 100 eV where the thermal, Coulomb and Fermi energies are nearly equal. Regimes of WDM include nuclear bursts, laser-plasma and particle beam-target interaction experiments. As WDM represents a complex regime at the interface of the condensed matter physics and plasma physics, the conventional theories developed for these fields are inadequate to predict the thermodynamic properties. The physics models that are based on reliable information directly derived from the WDM state, but not extrapolated from condensed matter or plasma systems, are required for high-fidelity predictions of thermodynamic and optical properties. A self-consistent quantum-mechanical (QM) treatment has to be implemented. The new development of advanced simulation tools is based on truly ab initio electronic structure methods beyond mean-field theories, able to predict reliably thermodynamic and optical properties of WDM. The equation of state and transport properties are determined on the atomistic scale, since the coupled, multi-physics behavior of the WDM regime is described from QM perspective. The proposed activities can significantly improve the understanding of material properties of WDM such as equations of state, electrical conductivity, optical properties under extreme conditions.
