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!
If you like cycling, have you considered cycling to UTSC? It's really fun!

I am currently looking for one or two new graduate students. If you are interested in working with me, please get in touch. I'm afraid, I don't have a list of ten amazing thesis projects which you can pick and choose from. I've found that item on such a list are often either really boring, or so interesting that I've already done them myself. So instead, I'd like you to have a rough idea of the topic that interests you most (Supernovas, Earth-like planets, FPGAs, etc). Then we can meet and come up with a well defined thesis project that combines your interests with my expertise and an open scientific question in astrophysics. At the end of the day, it's your PhD and you can do whatever you want! I'm just your advisor, sharing my own knowledge, directing you towards interesting problems, helping you avoid common mistakes, and making sure you get the most out of your PhD.
If you're an undergraduate student looking for a project in astrophysics, I might be able to supervise you. Since everything I do is computational, it would be great if you have some basic python knowledge to help get you started. I do not have a list of projects for you to choose from. Think about what interests you most. Then find some recent news articles or scientific papers in that area. We can then sit together and brainstorm about a project for you.
If you need a reference letter for a graduate school application or some other purpose, get in touch early, at least 4 weeks before the deadline. Writing letters takes a lot of time and I simply won't be able to write you one on short notice. When contacting me, please include your CV, a transcript, and what you are applying to.
For several years, I was in charge of the Astronomical Observatory at the University of Toronto Scarborough. Unfortunately, the observatory ceased operations in March 2019 due to changes in the university's priorities and recent construction work related to a new animal testing lab.
