Research Interests

Primary research interests of our Lab are Applied Mathematics, Space Plasma physics, Data Analysis, and Fluid Mechanics. We perform a full spectrum of analytical and computational work, from analysis experimental data to direct numerical simulations to nonlinear analytical models.

In Applied Mathematics, our main focus is numerical modeling and development of analytical methods for multi-scale nonlinear dynamical systems. The main applications are descriptions of chaos and mixing.

We apply Data Science and Physics-based AI/ML methods to Space Plasma systems. We analyze satellites’ measurements and use our understanding of data structure to develop numerical and analytical models of the Space weather.

We use Computational Fluid Dynamics (CFD) software packages (such as ANSYS Fluent) to describe liquid and gas flows in many engineering and biological systems: from interaction of high-speed trains with a tornado to the flow of blood through a heart-assisting pump.
