I study the long-term evolution of icy moons. My research program generally falls under the following questions: How do planets form and evolve? Why are planets and moons so diverse? What processes contribute to (or limit) habitability? Are we alone? Consequently, my projects often focus on large-scale processes such as ocean formation, metallic core formation, magnetic field production, volcanism, and ice-ocean dynamics—as well as planetary processes that may provide energy and nutrients to life elsewhere. I primarily use fundamental theory and numerical models, though I have co-developed (and sometimes lead) mission concepts to moons in the outer solar system, such as Triton and Europa. I work with Mike Brown, Jonathan Lunine, Steve Vance (JPL), and Dave Stevenson.
Outside of work, I like to spend time weightlifting, running, practicing mixed martial arts, cooking, and hanging out with my pet parrot.

My current work aims to understand the formation and dynamical evolution of planetary systems primarily through the study of debris disks. This involves exploring how planets and small bodies could interact to shape disk structures based on high-resolution imaging from infrared to millimeter wavelengths. I have recently been working to understand the diversity of debris disk radial profiles in the ARKS ALMA program, the age dependence of debris disk substructures and their connection to protoplanetary disks, unbiased methods to deconvolve and model disk images, and the origin of azimuthal disk asymmetries observed in systems like bet Pic and gam Oph. I work with Konstantin Batygin.
