PhD Candidate, Earth & Planetary Sciences

My work involves refining techniques that geochemists use to reconstruct the behavior of the global sulfur cycle, which is coupled to the carbon cycle through a series of (usually biological) reactions and supports inferences about the chemistry of the atmosphere and oceans over Earth’s history. In particular, I focus on a series of rocky outcrops near St. Louis that were deposited ~450 million years ago, at a time when exceptionally high sea levels had submerged much of the North American Midcontinent (then near the Equator) in a vast, shallow sea.
