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. And after a long wait but quite soon now, I look forward to using the James Webb Space Telescope in this research!

2015-July-28: HSC collaboration meeting

Anneya and I are in Princeton for the HyperSuprimeCam survey all-hands meeting.  This was a very exciting gathering as the HSC instrument is now hitting its stride and taking great data. I presented an update on our CLAUDS survey (which partners with the HSC survey) and there was a lot of enthusiasm from people wanting to use our U-band (near-UV) data in combination with the longer-wavelength HSC observations.
