Ph.D. Student in Earth System Science, admitted Autumn 2017
Current Research and Scholarly InterestsI study sterol side chain alkylation via sterol methyltransferases (SMTs), particularly in sponges and their bacterial symbionts. I aim to identify and characterize SMTs necessary for the biosynthesis of side-chain alkylated sterols in the sponge holobiont to improve our interpretation of unusual sterane biomarkers currently used to indicate demosponges, some of Earth’s earliest animals.
Postdoctoral Scholar, Earth System Science
Current Research and Scholarly InterestsI approach science questions from the molecular to the ecosystem level, such as (1) how abiotic pathways integrate into biological networks under extreme conditions, (2) what trace metals extremophiles require to maintain metabolic activity, (3) what novel methods can be applied to isolate extremophiles, and (4) how distinct trace gases cycle through extreme natural systems.

BioMarshall Burke is an associate professor in the Department of Earth System Science, deputy director at the Center on Food Security and the Environment, and center fellow at the Freeman Spogli Institute for International Studies (FSI) at Stanford University. He is also a faculty research fellow at the National Bureau of Economic Research, and a co-founder of AtlasAI, a remote sensing start-up. His research focuses on social and economic impacts of environmental change and on measuring and understanding economic development in emerging markets. His work has appeared in both economic and scientific journals, including recent publications in Nature, Science, The Quarterly Journal of Economics, and The Lancet. He holds a PhD in agricultural and resource economics from the University of California, Berkeley and a BA in international relations from Stanford University.

Ph.D. Student in Earth System Science, admitted Summer 2019
BioI grew up in Westmoreland, New Hampshire, and graduated from Dartmouth College in 2018 with an undergraduate degree in physics. I am broadly interested in atmospheric dynamics, idealized modeling, and climate change. My current research uses aquaplanet simulations to explore what factors determine global tropical cyclone frequency. My hobbies include hiking, birdwatching, and playing the piano.

Current Research and Scholarly InterestsResearch
I use stable and radiogenic isotopes to understand Earth system history. These studies examine the link between climate, tectonics, biological, and surface processes. Projects include: 1) examining the terrestrial climate history of the Earth focusing on periods of time in the past that had CO 2-levels similar to the present and to future projections; and 2) addressing how the chemical weathering of the Earth's crust affects both the long- and short-term carbon cycle. Field areas for these studies are in the Cascades, Rocky Mountains, Sierra Nevada, the European Alps, Tibet and the Himalaya and the Southern Alps of New Zealand.
Much of the research that I do has an international component. Specifically, I have collaborations with: 1) the Senckenberg Biodiversity and Climate Research Center in Frankfurt Germany as a Humboldt Fellow and 2) the Chinese University of Geosciences in Bejiing China where I collaborate with Professor Yuan Gao.
I teach courses at the undergraduate and graduate level in isotope biogeochemistry, Earth system history, and the relationship between climate, surface processes and tectonics.
