Research

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

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.

Mentoring:

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.

Courses

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. Pre or corequisite: any 200-level PHYS course. Some additional knowledge of astronomy (ASTRO 120 and/or 122) is advantageous.

Scholarly Activities

Research - Very Large Array Sky Survey

As co-chair of the Transients Science Working Group for the Very Large Array Sky Survey, I am working to maximize the scientific and outreach success of this three-epoch seven-year survey of the (northern) sky visible from New Mexico.
