Biography
I am an Assistant Professor at the Arizona State University School of Earth and Space Exploration. My research is focused on feedback processes in galaxy and structure formation, and the cosmological evolution and distribution of the elements.

The Emptiest Places A popular article describing our current understanding of the intergalactic medium, and its importance in the process of galaxy formation. |
The Sources of Intergalactic Metals Gives the results of a detailed observational program to determine the spatial distribution of intergalactic metals, and describes how these place strong constraints on the sources responsible for cosmological enrichment. |
|
The Type Ia Supernova Rate Shows how local observations of the Ia supernova rate require two components with different intrinsic timescales, a result that has strong implications for the cosmic evolution history of iron. |
AGN Feedback Causes Downsizing Discusses how feedback processes can help explain the puzzling observational result that the largest galaxies have finished forming their stars first. |

Triggering the Formation of Halo Globular Clusters with Galaxy Outflows Studies the impact of high-redshift outflows with "minihalos" with virial temperatures below the atomic cooling limit. Many of these interactions should trigger the formation of star clusters that reproduce three key features of the observed population of halo globular clusters. |
The Impact of Small-Scale Structure on Reionization Quantifies the effect of the smallest cosmological structures on the ionization history of the intergalactic medium. |
