The stable isotopes of water are critical tracers of both modern and past hydroclimate regimes. Current research activities include: measurement and interpretation of triple oxygen isotopes in modern precipitation, developing paleo-hydroclimate records using the hydrogen isotopic composition of leaf waxes, and synthesis of recent literature towards improved models of precipitation-to-leaf wax isotopic differences.

Jake Ogata Bernstein

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.

Callie Sharp

JD Candidate, Law

I will be co-president of the Energy and Environmental Law Society (EELS) at the law school for the '20-'21 academic year. My undergraduate research was conducted at Argonne National Laboratory and focused on organic carbon prediction methodology in the permafrost region. My work experience includes lab and field technician work for the DOE and work with university sustainability education programming, and I will be working as a legal extern for the EPA Office of Regional Counsel in Chicago during summer 2020.

JD Candidate, December 2021

I've spent my undergraduate career working as a research fellow and intern for organizations whose missions include environmental stewardship and study of nature and its processes. A focus of both the MO Sierra Club and Tyson Research Center included grassroots and community organizations.
