I teach a wide-range of undergraduate astronomy courses, bringing research-like inquiry to the students at all levels of the curriculum. I share many of these curricular materials at the link on the left, including the syllabus for a course on The Persistent Lack of Diversity in the Sciences.

The overarching theme of my research is to use comparisons between theory and observations of the local universe to learn about dark matter and galaxy formation. To do this, I:

  1. Search for nearly invisible galaxies throughout the Local Volume, using O/IR survey data
  2. Study the stellar halos of the Milky Way and other nearby galaxies, using O/IR survey data
  3. Use images and spectra obtained in pointed observations to study the invisible galaxies and stellar halos in detail
  4. Plan for the next generation of O/IR sky surveys, such as LSST
  5. Analyze N-body and N-body + SPH simulations of galaxy formation.
