I am an Associate Professor of Astronomy at Campion College, and also part of the Department of Physics in the University of Regina, SK, Canada. Previously, I was a Plaskett Fellow at NRC-Herzberg in Victoria, BC, Canada.

I am a dynamical modeler with a strong background in observational astronomy. I study the orbits of planets and how they evolve over time. By studying the orbits of Kuiper Belt objects and carefully taking into account observational biases, we can learn about how the giant planets migrated in the early days of the Solar System. In exoplanet systems, we can use the structure of debris disks (dusty disks around stars made by colliding asteroids) to find exoplanets that would otherwise be invisible.

I'm co-PI of the Classical and Large-a Solar System (CLASSY) Survey on CFHT, attempting to discover some of the smallest and most distant TNOs yet known.

Lately I've spent a lot of time thinking about, modelling, and measuring artificial satellites in low Earth orbit, which are increasing terrifyingly quickly, changing the night sky worldwide.

Are you a student looking for a supervisor?

I am usually looking undergraduate co-op (work term) students to work with me on various research projects, and I can supervise graduate students who have funding from outside sources (NSERC, etc). Take a look at my Science page and send me an email if these sorts of topics interest you!
