I'm interested in galaxies: how did they form and end up looking the way they do today? There are lots of different ways to attack this problem: my interest is in observational studies of both nearby galaxies and their star clusters and also distant, high-redshift galaxies. I've used quite a few different telescopes and instruments, with a lot of emphasis on infrared observations with the Spitzer Space Telescope.
