In fall 2023 I am teaching Astro 16 – Astrophysics: Stars, ISM,
and Galaxies including the lab component of the class.

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 hot, massive stars and their X-ray emission, which I study mostly via spectroscopy and modeling. I'm also interested in magnetic massive stars and their plasma magnetospheres and I've done some work on X-ray emission from pre-main-sequence stars as well. I have a long-standing interest in exoplanets and have worked on transiting systems along with my colleague Eric Jensen and many students, using our 24-inch telescope at the Peter van de Kamp Observatory. In the past I've worked on fusion-related plasmas and laboratory astrophysics experiments and modeling.
