I am a Professor in the Department of Astronomy & Astrophysics at the University of Toronto. I am also the Associate Chair for Graduate Studies in the department.

My area of specialization is observational cosmology, mainly focused on galaxy evolution. However, I enjoy learning about other areas of astrophysics, so at any given time I am probably working on a bunch of other things too. For example, at the moment I am working with my PhD students to build an instrument to find the first galaxies, am trying to develop a technique to find protostellar disks in galaxies halfway back to the Big Bang, and am exploring the best observational strategies to exploit adaptive optics.
