In spring 2024 I am teaching Astro 14 – Astrophysics:
Solar System and Cosmology and Astro 61 – Current Problems
in Astronomy and Astrophysics (Journal Club) as well as
Astro 94 – Research Project.



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.
