I am a computational astrophysicist and PhD student in the MIT Department of Earth, Atmospheric and Planetary Sciences. My primary research interests center around the use of numerical simulations and probabilistic algorithms for inference, data analysis, and inverse problems. I work primarily on the detection and characterization of asteroids, both for planetary defense purposes and as a lens to better understand the formation and evolution of the solar system. I have also worked on a range of other topics over the years, all through the lens of computational modeling and Bayesian data analysis, including nuclear security and disarmament issues, error propagation in guidance and navigation systems, the growth and movement of ancient human populations, and the reliability of renewable electricity generation in Europe.
I grew up just outside of Palmer, Alaska, and I now divide my time between Cambridge, Massachusetts and Seattle, Washington. When not working I can often be found trail running, climbing, or skiing uphill in Alaska, the Pacific Northwest, or New England.
