Associate Professor, Physical and Environmental Sciences, University of Toronto

I currently work at the University of Toronto at Scarborough where 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.

I'm very interested in numerical methods, in particular N-body codes and integration methods for planetary systems. Other research interests include planet formation, stochastic processes, planet migration, celestial mechanics, and Saturn's rings. I like to explore the posibility of using novel high performance computing platforms for astrophysics.

Make sure to check out my REBOUND code. It is an open source N-body code which gives you access to the world's fastest and most accurate numerical integrators. You can do almost anything with it from long-term symplectic orbit integrations to collisional shearing-sheet simulations of Saturn's rings. The installation takes literally 30 seconds and it comes with an easy to use python interface. 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 already downloaded it!
