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. -

Tianyang Guo (郭天阳)
Postdoctoral Scholar, Geological Sciences
BioDr. Tianyang Guo earned his Ph.D. degree in Rock Mechanics from the Department of Earth Sciences, the University of Hong Kong in 2020. He earned his bachelor's and master’s degree from Wuhan University (WHU) in 2013 and 2016, respectively. He was awarded the National Scholarship for Graduate in 2015 and graduated from WHU as an outstanding graduate. Before joining Stanford, he was a Postdoctoral Fellow in the Department of Civil and Environmental Engineering at the Hong Kong Polytechnic University (PolyU) under PolyU Distinguished Postdoctoral Fellowship Scheme 2021.
His research interests include (1) Cracking mechanisms and induced microseismicity during the injection of CO2 into reservoir rocks. (2) Application of machine learning in acoustic emission (AE) data interpretation. (3) Microcracking mechanisms of granite based on AE and microscopic observation.
