I’m a Heising-Simons Foundation 51 Pegasi b Fellow at the Massachusetts Institute of Technology. My research focuses on understanding the physical processes responsible for shaping planetary surfaces and climates, and see how we can use these worlds to learn more about our home here on Earth. I do this using a combination of data analyses, theory, laboratory experiments, and numerical simulations. I also work to develop and operate spacecraft that seek to explore the outer solar system, as much of my research interests and passions center around exploration by these active missions.
Two fascinating worlds have currently captured much of my attention: Titan, Saturn’s largest moon, has an active hydrological cycle matched in complexity only by our own Earth’s; and Comet 67P/Churyumov-Gerasimenko, the most well-observed small-body to date, one with landforms not dissimilar to those we’d find on Earth, despite the near lack of gravity. Though they are quite different from each other, they both continue to unveil new and interesting physics, which we will continue to leverage as we go forward exploring yet more of our solar system !
