Sarah is a research scientist with the DiRAC Institute. She studies small bodies throughout the Solar System ranging from near-Earth objects and main-belt asteroids in the inner Solar System to the Jupiter Trojans and Kuiper Belt objects near and beyond the giant planets. Her research program focuses on the orbital dynamics of Solar System small bodies, including resonant dynamics, near-Earth asteroids on retrograde (backwards around the Sun) orbits, temporary planetary co-orbitals, impact and crater formation rates (in particular on Pluto and Charon), asteroid-Earth impact probabilities and hazard mitigation, and asteroid observations. She is also focused on creating open-source software and increasing the accessibility of software packages commonly-used across the field of small body science.
