Sydney Aleah Hampton
Ph.D. Student in Oceans, admitted Autumn 2023
Master of Public Policy Student, Public PolicyBioSydney is a PhD student in the Oceans department, interested in using an interdisciplinary approach to explore the biophysical interactions of marine migratory species with their environment, and their responses to ecological and anthropogenic stressors. She is particularly interested in using what we know about various environmental variables and large-scale climate events to further predict and understand changes to the migratory patterns of marine species. Sydney holds a BS in Marine Science and BS in Experimental Psychology from the University of South Carolina.

Ronald Hanson
Clarence J. and Patricia R. Woodard Professor of Mechanical Engineering
Current Research and Scholarly InterestsProfessor Hanson has been an international leader in the development of laser-based diagnostic methods for combustion and propulsion, and in the development of modern shock tube methods for accurate determination of chemical reaction rate parameters needed for modeling combustion and propulsion systems. He and his students have made several pioneering contributions that have impacted the pace of propulsion research and development worldwide.

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.

Jerry Harris
The Cecil H. and Ida M. Green Professor in Geophysics, Emeritus
Current Research and Scholarly InterestsBiographical Information
Jerry M. Harris is the Cecil and Ida Green Professor of Geophysics and Associate Dean for the Office of Multicultural Affairs. He joined Stanford in 1988 following 11 years in private industry. He served five years as Geophysics department chair, was the Founding Director of the Stanford Center for Computational Earth and Environmental Science (CEES), and co-launched Stanford's Global Climate and Energy Project (GCEP). Graduates from Jerry's research group, the Stanford Wave Physics Lab, work in private industry, government labs, and universities.
Research
My research interests address the physics and dynamics of seismic and electromagnetic waves in complex media. My approach to these problems includes theory, numerical simulation, laboratory methods, and the analysis of field data. My group, collectively known as the Stanford Wave Physics Laboratory, specializes on high frequency borehole methods and low frequency labratory methods. We apply this research to the characterization and monitoring of petroleum and CO2 storage reservoirs.
Teaching
I teach courses on waves phenomena for borehole geophysics and tomography. I recently introduced and co-taught a new course on computational geosciences.
Professional Activities
I was the First Vice President of the Society of Exploration Geophysicists in 2003-04, and have served as the Distinguished Lecturer for the SPE, SEG, and AAPG. -
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.
