Since 2013, I am an Assistant Professor at the University of Toronto. I am a member of the Department for Physical and Environmental Sciences. My graduate appointments are at the Department of Astronomy and Astrophysics and the Department of Physics. My research interests are broad. They include planet formation, stochastic processes, planet migration, celestial mechanics, Saturn's rings, N-body codes, hydrodynamics, code development and high performance computing. Numerical methods are a big passion of mine.
Make sure to check out my REBOUND code. It is the only publicly available collisional N-body code. You can do almost anything with it from long-term symplectic orbit integrations to shearing-sheet simulations of Saturn's rings. The installation takes literally 30 seconds. It's really cool and I'm very proud of it.
You also don't want to miss the Exoplanet App. It is a free smartphone application for the iPhone/iPad that I wrote. It let's you explore almost the entire universe, including the cosmic microwave background, galaxy clusters, our Milky Way, the Solar System and all discovered extra-solar planets. Several million people have downloaded it already!
