Kinetic theory of plasmas; gyrokinetics in the core and pedestal of a tokamak; neoclassical transport in the core and pedestal of a tokamak.
Theoretical plasma physicist with research experience in tokamak, dipole, mirror, and bumpy torus magnetic confinement devices and laser ignited fusion. My most recent research interests include electric fields, flows, and profile evolution in turbulent tokamaks; background ion and impurity behavior in the pedestal of diverted tokamak plasmas; gyrokinetic descriptions of the background ions in a tokamak pedestal; finite Larmor radius effects on the parallel current on a three dimensional rational surface; optimized stellarators; and gravitationally confined equilibria and their stability.

Recent talks include a contributed presentation at the European Physical Society meeting in Lisbon (June 24, 2015) and a invited talk at the 8th Plasma Kinetics Working Group Meeting in Vienna (July 27, 2015). Both talks were on three-dimensional magnetized and rotating hot plasma equilibria confined by a gravitational field. In addition, he presented a tutorial on "Profile evolution and momentum transport in the core and pedestal" at the recent European Fusion Theory Conference in Lisbon (Oct. 5, 2015).
