My research focuses on the connections and interactions between ocean chemistry, biology and climate perturbations that relate to significant changes in oxygen concentrations. This work integrates geochemical, sedimentological and biological data to inform mapping and numerical modeling to understand the timing and spatial extent of major climatic perturbations. Untangling the biochemical evolution of early Earth and major climatic events is important to understand the ties to the biotic record. Understanding the timing and feedback mechanisms during oceanic (de)oxygenation events may give insight into future climate change; however, the picture remains unclear.
There are always oppurtunities to collaborate on projects and analysis in my lab and I am always looking for highly motivated and qualified individuals (students and postdocotral researcher) to work on various projects involving metal isotopes from the the entire geologic record.
