My interests include global biogeochemical cycles, their evolution over planetary history and their interaction with climate on multiple timescales. To address interesting problems in this broadly defined field of interest, I combine theory, models, observation and experiment.

Some of my work to date has been on the early evolution of the sulfur cycle on Mars and Earth, its coupling to the carbon cycle and its interaction with climate and with atmospheric evolution. More...

Another focus is investigating the effects of high abundances of CO2, such as those that existed around early Earth and Mars, on planetary climate. At present, it is uncertain just how much greenhouse warming a thick CO2-rich atmosphere provides. More...

Our understanding of early planetary climate and environmental conditions is only as good as our observational constraints. Providing such constraints through geochemical analysis or experimental work is another of my interests. More...

Other interests include the chemistry occurring in the interiors and atmospheres of the outer planet satellites. More...
