Research Interests:

My research is in the area of kinetic theory and simulation of plasmas. Most of my current work is in the area of direct numerical simulation of听听turbulence on large听听These simulations are done in a five dimensional phase space using newly developed particle-based methods. These calculations involve many millions of particles with self-consistently calculated electric fields. For the first time, these simulations are showing spectral features and transport levels at least qualitatively similar to turbulent transport observed in large present day experiments. Our goal is a fundamental understanding of plasma turbulence and transport in magnetized plasmas.听Scientific visualization is utilized to analyze the features of the three dimensional turbulent fluctuations.
