Andris Dimits is a theoretical and computational physicist, with interests and experience in magnetic fusion plasmas, nonlinear plasma dynamics, kinetic and fluid simulation techniques for plasmas, including derivation, implementation and application of gyrokinetic models, direct simulation and turbulence closures for fluids, as well as high energy density physics, including instabilities in radiative hydrodynamics. He is one of the originators of the δf method.
