Maura Dewey

Research Assistant: Maura Dewy

Maura is working on atmospheric science projects in the group, including the runaway greenhouse and PALEOTRIP. 

Honours student: Cedar Hanneson

Cedar is a student in the Joint EOS/PHYS Geophysics program. His honours thesis is on "The interpanetary magnetic field in the heliosphere: dependence on heliospheric distance"

Awards: Jamie Casels Undergraduate Research Award

Undergraduate researcher: 

Annaliese is a second year in the Microbiology program, starting research in astrobiology. 

Research Assistant: Lucas Kavenagh

Lucas is working peripatetically setting up the Palaeoclimate Radiative Transfer Intercomparison Project (PALAEOTRIP). 


USRA Summer student: Natasha Drage

Natasha worked on measurement of N in rocks, aimed at further developing the continental N budget. 

Workstudy student: Tanmana Sadhu

Tanmana is running the Community Climate Model, where she will be looking at changes to clouds under past climate conditions. 

MSc student: Claire Guimond

Claire has come to the group from McGill, to work on coupled climate and geochemical evolution of Venus 

Maura Dewey

Honours student: Maura Dewy

Maura honours thesis was on constraining the limit on outgoing thermal radiation from a moist atmosphere (the 'runaway greenhouse limit') using satellite meteorology.
Awards: Jamie Casels Undergraduate Research Award, Barnes Prize for the best honours thesis
Now: Competitive sailor & research assistant.

MSc student: Brendan Byrne

Brendan's masters project was on calculating high accuracy radiative forcings for modern day and Archean greenhouse gases.

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 (e.g. connected with the Victoria Schools Weather Network).
Grad students: Yes, I am hiring students! 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...
