Graduate student opportunities in data assimilation, glacier modelling, ocean modelling. Graduate degrees (2-year research-based M.Sc. or a Ph.D.) would be administered and awarded through Simon Fraser University, either through the Applied and Computational Mathematics program in the Department of Mathematics or the Department of Earth Sciences depending on background and research focus. Positions would come with funding for student stipend. I welcome interested students from a variety of backgrounds including mathematics, earth sciences, physics, computer science or engineering. Interested students should email me at for further details.

Paid undergraduate summer research opportunities exist through NSERC USRA (for Canadian students), please email me at if you are interested. Additional opportunities exist for Trinity Western University students, see here for further details. For international undergraduates (from Australia, Brazil, China, France, India, Germany, Mexico, Tunisia, and Ukraine) please apply for a Mitacs Globalink Research Internship.
