Alex is interested is in using DES to understand the fundamental nature of dark matter. His research focuses finding and studying Milky Way satellite galaxies, which are the smallest and most dark-matter-dominated galaxies known. The proximity, simplicity, and high dark matter content of these systems makes them ideal laboratories for testing the fundamental properties of dark matter.
Alex’s background is in experimental astrophysics, and he is involved in many aspects of DES operations, data process, and data analysis. Alex is co-convener of the Milky Way Science Working group and has previously served as coordinator of the Science Release Group.
We asked Alex a few more questions — here’s what he had to say:
What is your favorite part about being a scientist?
Do you have any hobbies or play any sports?
What is your favorite space-related image, and why?

I have always been really struck by Barnard’s Cloud (Barnard 68, right). A reminder that the absence of evidence is not the evidence of absence.
