About me

I moved to Haverford College in September 2014, where I am now a postdoctoral fellow. My current web page is

I was a lecturer and research associate in Astronomy at the University of Wisconsin-Madison, where I worked with Matt Haffner and Ron Reynolds. I use the Wisconsin H-Alpha Mapper (WHAM), a spectroscopic telescope located at the Cerro Tololo Interamerican Observatory in Chile. WHAM was designed and built at UW (before my time) and is remotely operable. The instrument spent 12 years at Kitt Peak in Arizona before we moved it to Chile. My research interests include observational studies of the warm, ionized component of the interstellar medium; and pulsars and pulsar scintillation.

My Ph. D. thesis is available in an unofficial, single-spaced format and double-spaced format.

In June-August 2010, I visited the University of Sydney and Bryan Gaensler's extreme astrophysics group as an NSF EAPSI fellow.

As an undergraduate at Oberlin College, I studied physics and astronomy and worked with Dan Stinebring, using pulsar scintillation to study the ISM.

See my publications page for copies of most of my papers. My CV and calendar are also available here.

I have a separate personal page.


In the summer of 2011, I taught Astronomy 103.

In the fall of 2006, I TAed for Astronomy 103, taught by Prof. Sparke.
