About Me

I'm an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, primarily working in high-energy astrophysics. I am involved with multiple X-ray observatories, and try to maintain a broad perspective regarding science priorities in astrophysics and their impact on mission requirements and capabilities. My research focuses on processes in the interstellar medium and on maintaining an atomic database (AtomDB) that is used throughout the field to model the spectra of hot collisional plasmas.

Education: In 1991, I received my B.S. in Mathematics and Physics from Carnegie Mellon University. I then went to the University of Wisconsin-Madison, where I worked with the Space Physics group and my advisor, Dr. Don Cox. I received my Ph.D in 1997 after writing a thesis titled "Modeling the Soft X-Ray Background with Multiple Supernovae".

Present Position: Associate Director - Science and Senior Astrophysicist, Smithsonian Astrophysical Observatory
