I am an observationally oriented theorist who uses a variety of tools — including analytic theory, (magneto)hydrodynamical simulations, radiative transfer calculations, semi-empirical and semi-analytic models, and even occasionally observations — to investigate a broad range of important open questions in galaxy formation. Much of my work has employed radiative transfer calculations to predict observable quantities from hydrodynamical simulations, thereby enabling direct comparisons with observations and tests of methods of observational inference. For this purpose, I use the Sunrise radiative transfer code, for which I am the primary maintainer. It is the most widely used code for predicting spectra and images from galaxy simulations (see the paper list here). I have devoted much effort to understanding submillimeter galaxies, an enigmatic population of rapidly star-forming high-redshift galaxies that have puzzled theorists since their discovery two decades ago. However, I have also done much work that is related to neither Sunrise nor submillimeter galaxies. Most recently, with Phil Hopkins, I developed an analytic theory for how stellar feedback simultaneously regulates star formation and drives outflows.
I invite you to browse the pages listed on the right for details regarding some of my research projects. However, the list is by no means exhaustive; for a more complete picture of my (published) research, it's best to do an ADS or arXiv search.
