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. -

Managing Director, Sustainability Accelerator
BioDr. Gemma Guilera is a chemist, an entrepreneur and an enabler of innovation. She currently serves as a Managing Director at the Sustainability Accelerator within the Stanford Doerr School of Sustainability.
Prior to joining the Accelerator, Guilera was Senior Manager at Plug and Play tech Center, an innovation platform and early-stage startup investment firm in Silicon Valley. Specializing in sustainable materials and packaging, she facilitated relationships between corporations seeking innovative solutions and the dynamic startup network at Plug and Play. Earlier to this role, Guilera was co-founder and CEO of Moving Beans, a venture backed-up sustainable startup developing more environmentally friendly, home-compostable materials for consumer goods.
During her time in the UK, Guilera was part of the original team that implemented the human-centered, solution-led Accelerator for Cities at Connected Places Catapult, where she led the startup team. The team provided support to startups in their growth journey through strategic multi-stakeholder engagement and accelerator programs. She also developed and led the open call for one of the largest large-scale IoT demonstrators globally, now the EU standard for innovative open calls.
Prior to her work in innovation, Guilera built the X-Ray Absorption Spectroscopy Beamline at ALBA Synchrotron (Spain), overseeing its construction and operation and conducting research in various areas such as catalysis and nanomaterials. Her career began as an industrial post-doc, followed by her role as a scientist at the ESRF (European Synchrotron Radiation Facility), where she worked in the field of heterogeneous catalysis and collaborated with Toyota to co-develop a three-way catalyst for petrol cars.
Gemma holds a BSc in Chemistry from the University of Barcelona, as well as an MSc in Supramolecular Chemistry and a PhD in Organometallic Chemistry from King’s College London. She was selected as one of the finalists in Women in Tech Global Awards 2021. -

James Harris
James and Elenor Chesebrough Professor in the School of Engineering, Emeritus
Current Research and Scholarly InterestsResearch interests have been in the areas of new electronic and optoelectronic device structures created by heterojunctions, quantum wells, superlattices and nanostructured materials. Molecular Beam Epitaxy (MBE) has been the foundation to prepare nanostructured metastable materials with atomic layer control and dimensions smaller than the wavelength of electrons. In this regime, quantum size effects can be utilized to create entirely new device structures based upon tailored transitions between quantum states and tunneling between states and structures. Past two decades focused on MBE growth of novel optoelectronic materials (GaInNAsSb) for long wavelength lasers and solar cells; quantum well structures for surface emitting lasers with power and bandwidth demands of AI now driving 10,000 element VCSEL arrays for optical interconnect; integrated nanophotonic structures for laser driven dielectric electron accelerators and free electron lasers (FEL) on a wafer for medical imagining systems; high speed optical modulators and non-linear optical effects for generation, control and application of ultra-short optical pulses; ultra-high efficiency multi-bandgap solar cells; world record solar to hydrogen conversion with water splitting; Si based photonic devices, including single photon avalanche detector (SPAD) for range finding and autonomous vehicles; implantable retina prosthesis with first human response in phase 1 human trials, 12/17.

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/ -

He teaches science and environmental communication and journalism in Stanford's School of Earth, Energy & Environmental Sciences and Graduate Program in Journalism. He came to Stanford in 2008, following a career of reporting and writing about science and environmental issues for national and international publications.
Hayden’s journalism career began at Newsweek magazine in New York, where he was an American Association for the Advancement of Science Mass Media fellow in 1997. In 2000, he moved to US News & World Report in Washington, DC, where he covered science, the environment, medicine, culture and breaking news as a senior writer. Since 2005, Hayden has been a freelance journalist. His cover stories have appeared in publications including Wired, Smithsonian, National Geographic, Washington Post Book World and many others. He has reported from South America, Europe, and Asia; and North America from New Orleans to the Canadian Arctic.

Currently, I am working at NOAA's Southwest Fisheries Science Center in Monterey, CA. My research interests span oceanography, fisheries ecology to climate change modeling, specifically examining species-habitat relationships in the ocean, predator-prey dynamics, and climate projections on marine top predator biodiversity. My publications have addressed a range of topics from fine-scale foraging ecology of top predators, dynamic ocean management of protected species, to modeling the effects of climate change on top predator habitat and biodiversity.

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. -
