I work to bring the history of science to diverse audiences, from middle school students to businesses and even to comedy events.

I focus on the various sciences of the stars in pre-modern Europe. In particular, I study how and why scientific experts made their knowledge useful to political leaders.

I teach courses at all levels of the curriculum, from introductory surveys to senior seminars. My seminars often explore particular, timely topics, e.g., next year’s seminar on extreme weather in pre-modern Europe.
