Research Group

Prospective students / postdocs

Please get in touch if you are interested in working with me! My publication list will probably be the best guide to the kind of work that I am doing. 
Upper level undergraduates: There are possibilities for SOES Honours projects (EOS499A/B) and summer students, and occasional workstyudy positions. Projects could be connected with my main research on the evolution of Earth and planetary atmospheres, or more general meteorology/climate.
Grad students: Yes, I am hiring students! Write to me, say why you are interested in working with me and enclose a copy of you CV and transcript. Funding is generally easier for students with an A- or higher average in the final two years of classes. Departmental information is here.
Postdocs: Get in touch...

In the here and now...

PhD Student: Julia Horne

Julia is joining the group in September 2017. 

Research Associate: Maura Dewey

Maura Dewey
Maura is working on a satellite meteorology project funded via Canadian Space Agency Earth System Data Analysis to observationally constrain the runaway greenhouse in Earth's tropics. Maura also competes for Canada sailing.

Maura is also an alum of the group, from Honours PHYS/EOS. 

Awards: Jamie Casels Undergraduate Research Award, Barnes Prize for the best honours thesis

Summer Student & Honours Student: Forest Pimm

Forest is re-evaluating ammonia as a potential greenhouse gas for the Archean.
