Christa studies how the orbits of extra-solar planets in multi-planet systems are currently arranged, and how those orbits evolve over long periods of time. She is also interested in how orbital evolution can affect the habitability of planets. Christa grew up in a small town outside of Vancouver, BC. She doesn’t remember a time when she wasn’t interested in astronomy. When in highschool she enjoyed physics, leading her to choose Physics and Astronomy as her major in university. She did her B.Sc. at the University of British Columbia, then her Ph.D. in Planetary Sciences at the University of Arizona. She is currently a postdoctoral fellow at the Canadian Institute for Theoretical Astrophysics, located in Toronto, Ontario.
