My research is on the nanoscale morphology evolution of surfaces under ion bombardment. In particular, I am interested in elemental and binary compound semiconductors under noble gas ion irradiation. Current projects investigate the nonlinear-regime evolution of nanopatterns using grazing incidence small angle x-ray scattering (GISAXS) at Brookhaven National Laboratory, stress accumulation in films during ion irradiation measured using a multi-beam optical stress sensor (MOSS), and composition variations in binary compound semiconductors. Recently, I have been learning to simulate these systems. I have been learning to use the monte carlo software SDTrimSP. I will also be traveling to the University of Helsinki in the upcoming months to collaborate with the Nordlund group on molecular dynamics (MD) simulations.
