My academic background is in planetary science, astronomy education research, and science teacher preparation.
My current planetary science research involves measuring trans-Neptunian Objects (TNOs) through stellar occultations. Marc Buie (Southwest Research Institute) and I lead the Research and Education Collaborative Occultation Network (RECON), an NSF-funded citizen science research effort with over 50 schools across the Western United States helping us measure TNOs as they pass in front of distant stars.
My current education research focuses on how inclusion of research opportunities as a component of K-12 science and math teacher preparation can impact teacher effectiveness, retention, and persistence. This work involves a longitudinal study of over 300 alumni of the STEM Teacher and Researcher (STAR) Program.
As Director of Fiske Planetarium, I also work with faculty, graduate students, and undergraduates to promote public engagement in STEM (science, technology, engineering, and mathematics) and conduct research into the effectiveness of teaching strategies and technologies in immersive planetarium environments.
