My primary research focuses on multi-wavelength observations of white dwarfs, neutron stars, stellar-mass black holes, and super-massive black holes (Active Galactic Nucleii), with a strong focus on those sources that are transient and/or variable. My other research interests include the transient radio-through-sub-mm Universe, globular clusters, the intergalactic medium, and data mining. I also have strong interests in Education & Public Outreach.


Teaching Areas:

Astronomy, Physics

Teaching Philosophy:

  • I want to share the excitement of astronomy with all of my students.
  • Mastering concepts is more important than simple memorization.
  • Mathematics and problem solving are essential skills, regardless of your major.


I am a strong believer in mentoring undergraduate and graduate students, whether as their official supervisor or as an unofficial mentor.
Please feel free to contact me if you are interested.


ASTRO 101 - Black Holes

An introduction to the science of black holes and its connection to how black holes are portrayed in popular culture and news. Topics include: properties of light; introduction to gravity, relativity and quantum physics; life cycle of stars; measurements of black hole properties; observed features of black holes interacting with their environment; event horizons, the ergosphere, and singularities; quantum black holes, information, and Hawking radiation; gravitational lensing; gravitational radiation. Prerequisites: Math 30-1. This course may not be taken for credit if credit has been obtained in ASTRO 122.

ASTRO 320 - Stellar Astrophysics I

Application of physics to stellar formation and stellar evolution; theoretical models and observational comparisons of main sequence stars, white dwarf stars, neutron stars, supernovae, black holes; binary star systems, stellar atmospheres and stellar spectra. Prerequisites: MATH 115, 118, 136, 146 or 156, and one of PHYS 124, PHYS 144, or EN PH 131, and one of PHYS 126, PHYS 146, or PHYS 130 and PHYS 208 or 271. Previous knowledge of astronomy is advantageous.
