Professional appointments

University of Toronto, Dept. of Physics, Toronto, Ont. 1999 to present
Research Associate, glacial cycle modelling and analyses. Current focus includes reconstruction of ice-sheet histories of the last glacial cycle using coupled climate, ice-sheet, and geodynamic models constrained by gravitational observations, relative sea level data, glacial geology, and other paleo proxies. I am also exploring the dynamical role of atmospheric carbon dioxide in the ice-age cycle using simple carbon-cycle models.

University of Georgia, Dept. of Geography, Athens, Ga, 1998-1999
Research Scientist. Continuation of climate dynamics research and teaching responsibilities.


University of Toronto, Dept. of Physics, Toronto, Ont. 1995-1998
Postdoctoral Fellow. Exploration of the dynamics of the ice-age cycle using coupled climate and ice-sheet models in order to elucidate the critical processes and feedbacks responsible for the 100-thousand year glacial cycle. This work involved both the development and modification of climate, geodynamic, and 3-dimensional ice-sheet computer models.
