I am an assistant professor of astronomy at Penn State.
I study stars, their atmospheres, their activity and their planets. I am a member of the California Planet Search consortium, and am a collaborator with the TEDI, the Triple-Spec Externally Dispersed Interferometer team.
I finished my PhD in 2006 with Geoff Marcy at UC Berkeley. My thesis included studies of stellar activity levels, their impact on radial velocity measurements, analyses of weak and long-period signals of exoplanets, and the Catalog of Nearby Exoplanets.
In 2006 I married Julia Miller Kregenow, who finished her PhD in astrophysics at Berkeley in May 2007.
For Fall 2009 I am teaching a graduate seminar: The Science of Exopanets (Penn State internal link).
