Research highlight

My primary interest is in the theoretical and computational modeling of transport properties of electrons and ions in dense plasmas. I use methods such as density functional theory, molecular dynamics, and kinetics to capture strong coupling and degeneracy effects in these plasmas. I am particularly interested in the role of non-equilibrium behavior and electron-electron scattering and correlation effects.
