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.
