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!

Euclid - now with SMU!

A number of Canadian astronomers are joining the Euclid Consortium thanks to the contribution of ground-based CFHT imaging, and I am among them. Check out the Saint Mary’s logo now on the Euclid front page [link here]! It’s been a long road and took many attempts (e.g., see here), but we are finally “in”.
