Bio

I am a geochemist and climate scientist who works on climate impacts on the water cycle, with a background in environmental science, engineering, and Earth science. I draw on my interdisciplinary training to study watershed responses to changes in hydroclimate, using both field and laboratory measurements as well as modeling approaches. I defended my Ph.D. in Earth System Science at Stanford University in 2018. I previously completed a M.S. in Geological & Environmental Sciences in 2014, and B.S. degrees in Civil & Environmental Engineering (Atmosphere/Energy) and Geological & Environmental Sciences in 2012.

Current Research and Scholarly Interests

I am a geochemist and climate scientist working on the water and carbon cycles in modern environments and over Earth history. I have academic training in environmental science, engineering, and Earth science. I draw on my interdisciplinary training to study past and present watershed responses to changes in climate using field observations, laboratory measurements and modeling approaches. I am currently a Postdoctoral Scholar in Geological Sciences at Stanford University. I received my Ph.D. in Earth System Science and M.S. in Geological & Environmental Sciences from Stanford University. My undergraduate training included B.S. degrees Civil & Environmental Engineering (Atmosphere/Energy) and Geological & Environmental Sciences from Stanford University.


My research includes:
- Investigating the influence of plants, geology and climate on nutrient and chemical fluxes in freshwater systems, including quantifying patterns of covariation between solutes and hydrology.
- Developing new modeling frameworks for investigating the response of terminal watersheds and lake systems to climatic forcings.
- Documenting past changes in climate using terrestrial geologic records as indicators of hydroclimate change to test the robustness of climate model simulations used for future projections.
- Developing new analytical geochemical techniques to infer how the atmosphere, water cycle and land surface reflect ongoing and past changes in climate.
