These pages are being overhauled in Spring '06.

My primary research themes are the first stars, the intergalactic medium, galaxy formation, and nucleosynthesis, using the tools of both theory and observing.

Click the links at left to find summaries of my work, links to papers and figures, model results, and code where available.

My work has been supported by NASA, NSF, at the University of Chicago by the Department of Astronomy and Astrophysics, and at Yale University through a generous gift by the Gilbert and Jaylee Mead Family Foundation.
