My primary research is focused on understanding inflation and the subsequent stage of reheating: the period when the universe first got populated with particles during the hot big bang. I am exploring the rich nonlinear dynamics during reheating, the initial conditions for reheating set up during inflation, and looking for possible observational implications. I am developing numerical methods which take advantage of high performance computing to improve our understanding of the evolution of non-equilibrium field theories. My broader interests include cosmological perturbation theory, solitons and cosmic defects, phase transitions in the early Universe, primordial gravitational waves, primordial black holes, magnetogenesis and baryogenesis.
