I am a member of the Institute of Theoretical Geophysics, in the Department of Applied Mathematics and Theoretical Physics, and I am studying for a Ph.D under the supervision of Professor John Lister and Dr. Jerome Neufeld. My research is on the topic of convection in porous media. There has been renewed interest in this field due to it's importance in the long-term storage of geologically sequestered carbon dioxide in saline aquifers; weak dissolution of sequestered CO_2 (which is buoyant) into the host brine results in the formation of a dense aqueous CO_2 solution, which can lead to downward convection and longer-term secure storage.
