Biography

I am an affiliate assistant professor in the University of Washington’s Department of Astronomy and a tenure-track assistant astronomer at the National Optical-Infrared Astronomy Research Laboratory (NOIRLab). I am also a member of the Rubin Observatory Community Science Team and I lead the Rubin Observatory Solar System Science Collaboration’s Near-Earth Objects and Interstellar Objects Working Group. My research program broadly focuses on orbital dynamics and impacts of small bodies across the Solar System. This includes studying main-belt asteroid resonances, resonant mechanisms that push asteroids onto retrograde (backwards around the Sun) orbits, asteroids orbiting the Sun closer than the Earth (Atiras and Vatiras), near-Earth object population modeling, co-orbital Solar System objects, impact and crater formation rates on Pluto & Charon, and Earth impact probabilities and hazard mitigation.
