I am Assistant Professor of Earth System Evolution at the School of Earth and Ocean Sciences at the University of Victoria, British Columbia (location).

My main research focus is on the coupled evolution of climate, geochemistry and life on the Earth and on Earth-like planets, particularly as seen through the atmosphere. The motivation of this research is understanding how the Earth evolved to its present state as the habitat for intelligent life, how life itself has influenced this evolution and the implications of this for planetary habitability elsewhere in universe. I have also conducted research evaluating the effectiveness of radiative transfer codes used for climate change prediction and been involved in observational physical oceanography and in work evaluating the effectiveness of proposed planetary geoengineering.

Previously, I was a research associate in the University of Washington Astronomy department and the Virtual Planetary Laboratory (part of the NASA Astrobiology Institute). Before that I was a NASA Postdoctoral Program Fellow at NASA Ames Research Center and before that a PhD student in the School of Environmental Sciences at the University of East Anglia.

Interested in working with me? See information for prospective students.
