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!

Ryan dotted the i’s and crossed the t’s on his BSc honours thesis entitled  Modelling the Properties of High Mass Galaxies at High Redshift.  This caps Ryan’s undergradute degree at SMU.  Congratulations, Ryan. Well done!


Bobby’s paper on the spatially-resolved SED fitting of nearby galaxies is accepted for publication in the MNRAS. This is an important piece of work as it not only uncovers an important systematic in the widely-used method of estimating masses of nearby, and distant, galaxies, but also provides a statistical remedy that shows how to alleviate its effects.
