Christa is a postdoctoral fellow at the University of British Columbia
(UBC). She’s from a small town just a couple hours east of Vancouver,
BC. She did her Bachelors in Physics and Astronomy at UBC, then did
her PhD in Planetary Sciences at the University of Arizona. She does
orbital dynamics, or, as she likes to call it “orbital shenanigans.”
She investigates how orbits change over long periods of time and how
that can be used to tease out interesting things about a planetary
system. In particular, she is interested in what the Kuiper Belt can
tell us about the history of our Solar System, and in how planetary
systems go unstable (or avoid going unstable). In her spare time she
works with the Yukon Center of the Royal Astronomical Society of
Canada (rasc.ca). As a result of that collaboration, this week she
will be on a flight to see the Aurora Borealis.
Christa tweets as @K04PB2B. Her twitter handle is the Minor Planet
Center (MPC) packed designation for the Kuiper Belt object 2004 PB112,
which orbits 4 times in the time it takes Neptune to orbit 27 times.
