  • Laura Frouté

    Laura Frouté

    Postdoctoral Scholar, Energy Science and Engineering

    Current Research and Scholarly InterestsLaura is a postdoctoral scholar at Stanford University, working on subsurface engineering solutions for the energy transition. Part of her research focuses on replicating geological hydrogen production in the laboratory and identifying and mitigating reactivity constraints at the microscale. Her research also focuses on investigating carbon storage into various basalt formations by measuring their carbon mineralization potential. Her expertise includes designing laboratory-scale pilots and conducting research on rock formations in the context of hydrocarbon production, carbon storage, and hydrogen production to understand the interplay of geochemistry, reaction mechanisms and complex storage and transport processes across length scales. To study the evolution of porous media properties following reaction or transport experiments, she uses a wide spectrum of multiscale, multimodal material characterization techniques (sorption, XRD, XRF, μCT, FIB-SEM, TEM). She holds a MS in Chemical Engineering from ENSIC (France) and a PhD in Energy Science and Engineering from Stanford University. Her interests range from subsurface engineering, fluid flow in porous media, to environmental and regulatory issues in the oil & gas industry, CCUS, climate solutions and energy policy.

  • Tianyang Guo (郭天阳)

    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.

  • Alex Hedgpeth

    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.

  • Alexander Honeyman

    Alexander Honeyman

    Postdoctoral Scholar, Earth System Science

    BioI work at the intersections of data science, field work, laboratory experimentation, biogeochemistry, and microbial ecology. I was exposed to the issue of wildland fire through 10 years of experience as a volunteer firefighter / EMT in Colorado (fire / rescue / EMS). My current work involves investigating the geochemical character of wildfire smoke by hybridizing analyses of physical samples with various geospatial datasets and atmospheric particle transport models. I love working in environmental systems because they are complex, and offer numerous opportunities to blend the physical and computational sciences.

  • Qi Hu

    Qi Hu

    Postdoctoral Scholar, Energy Science and Engineering

    BioI am a postdoctoral scholar collaborating with Tapan Mukerji on developing innovative workflows for monitoring subsurface CO2 sequestration. My research primarily involves integrating advanced seismic inversion techniques, such as full-waveform inversion, with rock physics and fluid dynamics to glean insights into subsurface structures and behaviors. Additionally, I am intrigued by the potential of distributed acoustic sensing and machine learning algorithms in various topics related to energy transition.

  • Cameron S. Kay

    Cameron S. Kay

    Postdoctoral Scholar, Environmental Social Sciences

    BioCameron S. Kay is a postdoctoral scholar in the Climate Cognition Lab at Stanford University. His research explores the psychological foundations of antisocial beliefs and behaviours, including why people believe in conspiracy theories, harbour prejudicial beliefs, and gaslight others. To support this work, he develops psychometrically sound scales and tools for improving data quality. Before joining Stanford, Cameron was a visiting assistant professor at Union College in Upstate New York. He earned his PhD in psychology with a specialization in quantitative research methods at the University of Oregon, where he also completed master’s degrees in psychology and journalism. He holds a BA in psychology from the University of British Columbia.

  • Jonas Kloeckner

    Jonas Kloeckner

    Postdoctoral Scholar, Earth and Planetary Sciences

    BioJonas Kloeckner is a Postdoctoral Fellow at the Stanford Doerr School of Sustainability, sponsored by the Stanford Institute for Human-Centered Artificial Intelligence (HAI).
