Emily Geyman
Postdoctoral Scholar, Geophysics
BioI am a Stanford Science Fellow and postdoctoral scholar in the Department of Geophysics, working with Ching-Yao Lai. My research explores the connections between landscape dynamics, the global carbon cycle, and climate. I combine field observations, remote sensing, and physical models, often using space-for-time substitutions: natural experiments in which spatial patterns help reveal processes that unfold over timescales too long to observe directly.
At Stanford, I use optical and radar satellite observations to investigate how meltwater drainage beneath the Greenland Ice Sheet controls ice motion and its response to warming. I completed my Ph.D. at Caltech, where I studied how river migration and permafrost shape carbon cycling in Arctic landscapes, alongside projects investigating the controls on mountain erosion and post-wildfire debris flows.
Before Caltech, I worked at the Norwegian Polar Institute, reconstructing 80 years of glacier change across Svalbard to understand how climate and glacier geometry govern ice loss. I earned my B.A. in Geosciences at Princeton, where I combined fieldwork on modern carbonate sediments in the Bahamas with biogeochemical and stratigraphic models to understand how carbonate rocks record ancient sea level and ocean chemistry. This work informs how we read the geological record to reconstruct Earth’s climate and carbon-cycle history.
