Research

I am interested mainly in gyrokinetic particle simulation of turbulence and transport. Within this research I am involved in the Summit Project, a multi-institutional collaboration on the development of large-scale electromagnetic simulations of plasma transport. As part of this project I developed a gyrokinetic particle code GEM, which is the only particle code capable of treating both kinetic electrons with the realistic ion-electron mass ration and the finite beta effects.
