My focus is on astronomy and physics education. I teach introductory courses and engage the community with outreach events sponsored by the Madison-Macdonald Observatory. Public observing nights are offered April – October, the first and third Friday of the month. Regular updates to the observing schedule are posted on www.twitter.com/CSUskies and www.facebook.com/CSUskies.

Before focusing exclusively on education, I did research in the field of astrobiology. My prior research includes searching for methane lakes on Titan, investigating the evolution of young stellar systems, and observing extrasolar planet transits.
