Last year I taught Astro 16 – Astrophysics:
Stars, ISM, and Galaxies
and Astro 123 – Stellar Astrophysics.

Information about astronomy and physics course offerings
is available on the department website or in greater detail
in the course catalog.

My primary research interests involve the radiation-driven winds of massive, hot stars and their X-ray emission. I'm also interested in magnetic massive stars and their plasma magnetospheres. And I have a long-standing interest in exoplanets which I study, along with the colleague Eric Jensen, using our 24-inch telescope at the Peter van de Kamp Observatory. We also do some photometry of magnetic massive stars, measuring rotation properties.
