1. Observational cosmology

  2. Formation and evolution of galaxies

  3. Formation of stars over cosmic time

  4. Photo-z and SED-fitting techniques

I study the formation and evolution of galaxies at epochs when the Universe was only a fraction of its present age. I am particularly interested in where and when the Universe made its stars and the complex chemical elements that we are all made of. In my work I use space-based facilities including the Hubble and Spitzer Space Telescopes, as well as ground-based ones such as the Keck, Gemini, and Magellan observatories in Hawaii and Chile.

The first set of deep CFHT U-band observations of the HSC survey fields (The CLAUDS project) has been taken during the late-August dark run!  Approximately 13 hrs, including a significant number of images in truly excellent seeing. The project is off to a great start!  (Big thank you to CLAUDS team member Steve Gwyn for a rapid reduction of the data shown in the image!).
