Research Description

Dr. Anistratov works in the field of computational physics, transport theory and numerical analysis. His research interests involve numerical methods for solving particle transport and radiative transfer problems. These kinds of problems arise in such areas as reactor physics, astrophysics, medical physics, geophysics and atmospheric sciences. His research includes development and analysis of iteration methods for the transport equation, discretization methods for partial differential equations, methods for solving transport equation coupled with equations of matter, and mathematical models of transport process in various physical systems.
