I am interested in investigating the interactions of climate, atmospheric chemistry, and geologic processes through Earth History. Specifically, my research focuses on the effects of the Great Oxidation Event on climate and atmospheric chemistry. The Great Oxidation Event fundamentally changed the Earth’s surface redox conditions, increasing the atmosphere’s oxygen content and affecting the Earth’s biochemical cycles. Multiple lines of evidence suggest that the Earth suffered a period of climatic upheaval after the Great Oxidation Event, going from periods of global glaciations to periods of stability. My research tries to understand why climate behaved like this after the Great Oxidation Event and how these changes in climate could have affected the atmospheric chemistry of the Earth and vice versa. I am using a combination of photochemical, climate and simple mass balance models to try to understand these problems.
