Research Interests

My research focuses on the search for exomoons in time-domain photometry, particularly in Kepler, K2, TESS, HST, and JWST data. These worlds stand to tell us a great deal about the formation and dynamical history of planetary systems, and could potentially be attractive places to search for life in the decades to come. But we have to find them first! These days I'm particularly interested in the application of machine learning to various observational challenges, and developing novel techniques to the finding and characterizing exomoons.
