research group and opportunities

I am an observational astrophysicist, with interests in active galactic nuclei, galaxy evolution, large-scale structure of the Universe, the cosmic X-ray background, and X-ray binary stars. My work uses data from the Chandra, XMM-Newton, Hubble, Spitzer, Herschel, and WISE space telescopes as well as ground-based optical, infrared, and radio observations.

I joined the Department of Physics and Astronomy at Dartmouth College in December 2011. My research is generously funded by the NSF, NASA, and previously by an Alfred P. Sloan Research Fellowship. My full CV is here. I am looking for interested and motivated students to take part in an exciting research program.
