Plasma physics relevant to magnetic confinement fusion, astrophysical jets, solar corona, and  earth’s  magnetosphere.

Our group's research emphasizes close coupling between experimental and theoretical plasma physics, both fundamental and applied. Typically, unexpected experimental results motivate new theoretical interpretations, or a new theory suggests a new experimental interpretation. Our research spans several different areas of plasma physics that share related concepts. In particular, we are investigating spheromak plasmas, a configuration that provides a possible low-cost path for  magnetically confined fusion energy that could ultimately provide electric power for a city. The physics of spheromak formation is related to the physics of solar corona loops and to astrophysical jets because spheromaks, coronal loops, and astrophysical jets are governed by essentially the same set of magnetohydrodynamic equations and differ only in boundary conditions.  A detailed description and a continuously updated publication list is provided at the Research Group.
