I am interested in a variety of topics in star formation. Primarily,
The formation of massive stars and massive star clusters.
How stellar feedback — the injection of energy and momentum from young stars — limits star formation and affects the dynamics of HII regions.
Star cluster disruption and its dependence on total stellar mass.
The goal of my research is to understand which stellar feedback processes dominate the star formation process for massive stars and massive star clusters, and to determine how feedback from the most massive stars in these clusters can limit star formation and may lead to the cluster’s ultimate disruption. I develop new numerical methods and perform simulations using the three-dimensional radiation-magnetohydrodynamics adaptive mesh refinement code ORION to work on these problems.
