I’m a Research Associate at the Cornell Center for Astrophysics and Planetary Sciences at Cornell University. My research focuses on understanding the evolution of the surfaces of planets, moons and small bodies in the outer solar system, and deciphering what these surfaces tell us about their past. I do this using both spacecraft observations of their surfaces, and numerical simulations. Currently, my research focuses on the evolution of the landscapes of Titan, Saturn’s largest moon, and the surfaces of small bodies like Comet 67P/Churyumov-Gerasimenko.
