Professional Interests

I am a broadly trained geologist with interest in the interactions between life, the geochemical environment, and climate. My research is focused on understanding the Earth system feedbacks that are important to ocean deoxygenation. Most of my work has centered on understanding the development of anoxic and sulfidic conditions during the end-Permian mass extinction and recovery. I use a range of tools, including numerical modeling and isotope geochemistry.
