Research

The Fusion and Astrophysical Plasma Physics Group develops theoretical framework models of how plasmas move and interact with magnetic fields and boundaries. Numerical simulations are used to model turbulence, transport, gradient relaxation, pattern formation, and system stability, among other properties.

These models provide insight into the phenomenology of plasma and help to guide large-scale simulations used to develop fusion energy technology.
