Abstract:
A recent surge in the generation of empirical records for Earth’s redox chemistry has yielded substantial progress in our ‘broad stroke’ understanding of the Earth’s oxygenation history. However, significant gaps remain in our mechanistic understanding of Earth’s chemical evolution, and in particular the cause-and-effect relationships with evolving biosphere. Many of these gaps arise, in part, from a lack of coherent mechanistic frameworks for quantifying the evolution of atmosphere/ocean in response to biological evolution. The overarching goal of my research is to develop a general framework for the coupled evolution of life and the atmosphere on Earth (and Earth-like planets more broadly). Understanding the biogeochemical evolution on Earth has great ramifications not only for the future of our planet but for the search for life elsewhere. In this talk, I will present a couple of modeling results that we have obtained in the last few years and discuss the future direction and potential synergies with ELSI research.
