Yahui He
Postdoctoral Scholar, Archaeology
BioYahui He is an environmental archaeologist specializing in archaeobotany in East Asia. Her research investigates the dynamics of human-plant relationships in multi-scalar socio-political contexts, focusing on the materiality of plants in processes of sedentism and urbanism.
Her PhD and ongoing research work in the Northern Zone, China (northern Loess Plateau and southern Mongolian Plateau) utilizes multi-proxy methods, including starch, phytolith, fungi, and use-wear analyses, to explore plant-based food and drink practices across different social contexts, such as household, community, and mortuary settings. Yahui’s collaborative research extends to studies on plant exploitation and dispersal, as well as related technologies such as plant food fermentation and bast fiber production across mainland China and beyond, including Erlitou in Henan and others in Taiwan and Honduras.
Prior to joining the Stanford Archaeology Center as a postdoctoral scholar, Yahui obtained her PhD at Stanford in 2024 and was a Li Foundation Fellow at the Needham Research Institute in Cambridge, UK in 2024 (Jan.-June). -
Laura Heath-Stout
Postdoctoral Scholar, Archaeology
BioI am an intersectional feminist archaeologist and activist. I use qualitative and quantitative social science methods to study the demographics and knowledge production practices of archaeologists. I am currently starting a new community-driven project about the history of institutions for people with disabilities in Massachusetts.

Alex Hedgpeth
Postdoctoral Scholar, Earth System Science
BioAlexandra Hedgpeth is a biogeochemist whose research explores how soil carbon cycling in peatlands responds to environmental change. Her work focuses on understanding the mechanisms that regulate carbon storage and greenhouse gas production in both tropical and boreal wetlands, with a particular emphasis on the vulnerability of deep, ancient carbon to modern surface inputs and hydrologic shifts.
Through her Ph.D. research at the University of California, Los Angeles, Alex has developed and applied novel isotopic and geochemical approaches—including implementing radiocarbon dating, stable isotope analyses, and high-resolution molecular characterization—to trace the sources and fates of carbon in peat soils. Her fieldwork spans a range of ecosystems, from ombrotrophic bogs in the Arctic to saturated tropical peat domes in Central America. This comparative framework allows her to identify unifying controls on carbon preservation and loss across climate zones.
Alex's research integrates field measurements, laboratory experiments, and synthesis of global datasets. She is a key contributor to multi-institutional efforts to model peatland carbon cycling under climate change scenarios, including DOE- and NSF-supported initiatives. Her work helps clarify the role of peatlands as both long-term carbon sinks and potential sources of atmospheric CO₂ and CH₄ under future disturbance.
In addition to her scientific contributions, Alex is committed to collaborative, interdisciplinary research and has worked closely with partners at national laboratories, the Smithsonian Tropical Research Institute, and international data synthesis networks. She is especially interested in questions with high uncertainty and high relevance to climate feedbacks—such as thresholds in biogeochemical function and the persistence of deep soil carbon under hydrologic change. -
Chris Heitzig
Postdoctoral Scholar, Epidemiology
BioChris Heitzig is a New Map of Life Postdoctoral Fellow in the Department of Epidemiology and Population Health. An economist by training, his research develops models to examine healthy aging across the life course, with a particular emphasis on identifying causal pathways and key points of policy intervention to improve well-being in later life. A central focus of his work is the socioeconomic impact of undiagnosed metabolic disorders—how these conditions manifest, the costs of leaving them untreated, and the potential for interventions to improve detection and outcomes. His research combines insights from economics and public health with machine learning methods for causal inference.
Before joining Stanford, Chris served in research roles at the Brookings Institution and the World Bank. At Brookings, he managed a $1.5 million research grant investigating how technological change is reshaping employment in Africa. At the World Bank, he designed randomized controlled trials to measure the causal effects of health and employment programs and served in an operational role as the day-to-day lead for a $20 million job transition program. Chris holds a PhD in Economics from the Institute of Development Studies, an MPhil in Economics from the University of Oxford, and a BA in Economics from Saint John’s University. -
Aoife Henry
Postdoctoral Scholar, Mechanical Engineering
BioAoife Henry earned her doctorate in Electrical, Computer & Energy Engineering at the University of Colorado, Boulder, funded by and in collaboration with the wind energy control systems team at the National Renewable Energy Laboratory (NREL). During her doctorate, she applied her joint specializations of machine learning and control systems to implement and validate forecast-enabled wind energy controllers using state-of-the-art time-series forecasting models. She is now working to commercialize and scale this technology under the wing of the Stanford Sustainability Accelerator Fellowship at the Doerr School of Sustainability.
