1. Formation and evolution of galaxies

  2. Formation of stars over cosmic time

  3. 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!

GIRMOS funded

Canada Foundation for Innovation today announced funding to build, over the next five years, the Gemini InfraRed Multi-Object Spectrograph (GIRMOS).  See SMU’s press release here.

GIRMOS is an instrument for Gemini that will use adaptive optics and multiple intergral-field spectroscopy units to study the detailed working of galaxies in the distant universe.

SMU’s part in the project is to develop the data simulator and data reduction pipeline... and, of course, we also plan to use it for observing distant galaxies once GIRMOS is on the telescope in 2023 or so.

  1. Canadians interested in joining our group: the December 1st NSERC PGS-M scholarship deadline is approaching! Please contact me about applying for this scholarship if you would like to join our group to work on distant galaxies with our incoming guaranteed-time James Webb Space Telescope (JWST) data or the wide-field CLAUDS survey.
