Martin Grove
Professor (Research) of Earth and Planetary Sciences
Current Research and Scholarly InterestsResearch
I study the evolution of the Earth's crust by undertaking petrologic and geochemically-based research that is grounded with fieldwork. I co-direct the Stanford-USGS ion probe laboratory and develop geochronologic methods to constrain crystallization, metamorphic, and metasomatic histories of the middle to deep crust. Similarly, because heat flow characteristically attends mass transfer during crustal deformation, I employ 40Ar/39Ar and (U-Th)/He thermochronology to extract thermal history information from minerals to constrain the timing and magnitude of fault slip as well as erosional and tectonic denudation. Finally, I am heavily involved in provenance studies to constrain aspects of crustal deformation and erosion that are only preserved in the sedimentary record. -

John A. Harrison
Visiting Professor, Earth System Science
BioDue largely to human activities associated with food and energy production, the world is experiencing an un-precedented mobilization of nutrients such as nitrogen (N) and phosphorus (P). A substantial portion of this mobilized N and P flows into streams and rivers, and eventually down to coastal waters, where nutrient over-enrichment has been associated with a host of environmental impacts. En route to the ocean, these nutrients can alter ecosystem function as well as the balance of atmospheric greenhouse gases.
I use experimental and spatially explicit modeling approaches to elucidate processes governing the mobilization, transport, transformation, and ecosystem/biogeochemical impacts of land-based N, P, and other bio-active elements. For more information about me and my research group, please see my Washington State University research page: https://labs.wsu.edu/gcwblab/ -

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. -

Leo Hollberg
Professor (Research) of Physics and of Geophysics
BioHow can we make optimal use of quantum systems (atoms, lasers, and electronics) to test fundamental physics principles, enable precision measurements of space-time and when feasible, develop useful devices, sensors, and instruments?
Professor Hollberg’s research objectives include high precision tests of fundamental physics as well as applications of laser physics and technology. This experimental program in laser/atomic physics focuses on high-resolution spectroscopy of laser-cooled and -trapped atoms, non-linear optical coherence effects in atoms, optical frequency combs, optical/microwave atomic clocks, and high sensitivity trace gas detection. Frequently this involves the study of laser noise and methods to circumvent measurement limitations, up to, and beyond, quantum limited optical detection. Technologies and tools utilized include frequency-stabilized lasers and chip-scale atomic devices. Based in the Hansen Experimental Physics Laboratory (HEPL), this research program has strong, synergistic, collaborative connections to the Stanford Center on Position Navigation and Time (SCPNT). Research directions are inspired by experience that deeper understanding of fundamental science is critical and vital in addressing real-world problems, for example in the environment, energy, and navigation. Amazing new technologies and devices enable experiments that test fundamental principles with high precision and sometimes lead to the development of better instruments and sensors. Ultrasensitive optical detection of atoms, monitoring of trace gases, isotopes, and chemicals can impact many fields. Results from well-designed experiments teach us about the “realities” of nature, guide and inform, occasionally produce new discoveries, frequently surprise, and almost always generate new questions and perspectives. -

He was also involved in the development of the understanding of the key role played by the phase composition and oxygen stoichiometry in determining the properties of high temperature oxide superconductors.
Topics of particular recent interest have been related to energy conversion and storage, including hydrogen transport and hydride formation in metals, alloys and intermetallic compounds, and various aspects of materials and phenomena related to advanced lithium batteries.
He has over 400 professional publications, including three books; "Advanced Batteries", published by Springer in 2009, "Energy Storage", published by Springer in 2010, and Energy Storage, Second Edition in 2016. -

Stepfan Huntsman
Ph.D. Student in Geological Sciences, admitted Winter 2022
BioI've had an interest in rocks and fossils since I was a small child, amassing a large collection in my youth, but hadn't considered it a viable career path instead starting my path as a social scientist studying gender and sexuality. My interest in a career in paleontology peaked after finishing my first degree, leading me to pursue a second bachelors degree. While working on my undergraduate at Weber State I discovered a true deep love of plants as well as a curiosity about the methods they use to adapt to new environments, which has lead me to pursuing a doctoral degree here at Stanford University.
