Sarah is an Asteroid Institute senior researcher. Her research interests include near-Earth asteroid orbital dynamics, main-belt asteroid resonances, co-orbital solar system objects, impact and crater formation rates, resonant mechanisms that create asteroids on retrograde orbits, near-Earth object population modelling, near-Earth object candidate follow-up, characterization of objects of interest to NASA and upcoming targets of radar observations, measuring the Yarkovsky effect for near-Earth asteroids, and the asteroid impact hazard threat and possible mitigation techniques.

She received her PhD in 2015 from the University of British Columbia. Learn more about her work at www.sarahgreenstreet.com.
