Welcome! I joined the Harvard Astronomy Faculty as an Assistant Professor in 2010. My research focuses on the catastrophic death of stars, "supernovae". By combining astronomical data sets from telescopes and satellites, I probe the eruptive, destructive, and explosive nature of supernovae and their role in the Universe. For more discussion of my research, check out the Supernova Forensics page. As a faculty member, I teach Astro100 ("Observational Astronomy") and Astro120 ("Stellar Physics") for undergraduates, and Astro301hf ("Journal Club") for graduate students. Check out the Astronomy Courses page for more information.
