Research interests
My research is focused on the mathematical analysis of both deterministic and stochastic PDEs arising in fluid mechanics and plasma physics. I am currently specifically interested in understanding mixing, turbulence, and the stability of coherent structures in 2D and 3D fluid mechanics at high Reynolds number and Landau damping-related kinetic effects arising in plasmas in the collisionless limit.
My research is currently funded by an NSF CAREER grant.
For information on the courses I am currently teaching and on past or present reading groups I am involved in, see the below links.
