Virginia Walbot
Professor of Biology, Emerita
Current Research and Scholarly InterestsOur current focus is on maize anther development to understand how cell fate is specified. We discovered that hypoxia triggers specification of the archesporial (pre-meiotic) cells, and that these cells secrete a small protein MAC1 that patterns the adjacent soma to differentiate as endothecial and secondary parietal cell types. We also discovered a novel class of small RNA: 21-nt and 24-nt phasiRNAs that are exceptionally abundant in anthers and exhibit strict spatiotemporal dynamics.

John J. Walker
Technology Administrator, JSK Journalism Fellowships
BioJohn J. Walker is technology administrator for the JSK Journalism Fellowships. He manages all the software and digital infrastructure that keeps the fellowship running and accessible to applicants and collaborators from around the world and within the Stanford community. This includes the fellowship application platform, the JSK website and the various tools the program uses to communicate and collaborate.
John started working at Stanford in 1999. Previously he was web administrator for the Department of Communication and the technical director of the Political Communication Lab. There he created experimental manipulations for social science research, like testing people’s responses to political ads. Before Stanford, he worked at Sun Microsystems as a software developer.
John has a master’s degree in communication from Stanford, as well as master’s and bachelor’s degrees in computer science from the University of California at Riverside.

Matías Walker
Ph.D. Student in Philosophy, admitted Autumn 2026
Current Research and Scholarly InterestsI'm interested in making contributions on both the metaphysical and logical fronts of philosophical questions. My doctoral project will combine tools from modal logic, model theory, higher-order semantics and formal metaphysics, with particular attention to the relationship between logical structure and its semantical reach in metaphysical interpretation.

Zach Wallis
Ph.D. Student in History, admitted Autumn 2026
BioZach Wallis is a PhD student in the Department of History in the field of British history. His research focuses on political economy, energy, and the environment in Australia, New Zealand, and the Southwest Pacific in the late nineteenth and early twentieth centuries. He is especially interested in understanding how conjoined political-economic and environmental transformations across the Pacific in this period prefigured the Great Acceleration in significant ways. Some of his other research interests include the environmental history of the First World War, historical theory, and theories of socio-metabolism.
Before coming to Stanford, Zach earned a B.A. in history from McGill University, a Master of History from the Australian National University, and a M.A in history from the University of Chicago. His dissertation at the University of Chicago, which won the Raymond D. Fogelson Thesis Prize, was a study of settler ecological thinking in late nineteenth century New Zealand. He has also previously undertaken research into late nineteenth and early twentieth century Australian intellectual history, and he has been published on the topic in History Australia. -
Patrick Walsh
Ph.D. Student in Applied Physics, admitted Autumn 2025
Student Trainer, Stanford Nano Shared FacilitiesBioPatrick graduated with honors from the University of Wisconsin-Madison in 2025 with a B.S. in Applied Math, Engineering, and Physics. He conducted his undergraduate research under Professor Mark Eriksson, where he studied Semiconductor Quantum Dot Qubits. His work focused on developing experimental techniques and numerical tools to automate gate-voltage calibration procedures for quantum dot devices. As an NSF Fellow and graduate student with the Bøttcher group at Stanford, Patrick is interested in using Josephson Junction Arrays to study a variety of problems in condensed matter, including vortex dynamics, quantum phase transitions, and novel material platforms.

John Walters
Ph.D. Student in Chemistry, admitted Autumn 2024
Current Research and Scholarly InterestsI am interested in the attosecond dynamics of atoms and molecules. Specifically, my interest lies in investigating the effect of electron-electron correlation and the influence of non Born-Oppenheimer dynamics on isolated quantum systems to drive understanding of both ground-state and excited-state processes. Additionally, I am interesting in applying covariance and machine-learning based techniques to improve measurement resolution in high-repetition rate experiments.

Guenther Walther
John A. Overdeck Professor
BioGuenther Walther studied mathematics, economics, and computer science at the University of Karlsruhe in Germany and received his Ph.D. in Statistics from UC Berkeley in 1994.
His research has focused on statistical methodology for detection problems, shape-restricted inference, and mixture analysis, and on statistical problems in astrophysics and in flow cytometry.
He received a Terman fellowship, a NSF CAREER award, and the Distinguished Teaching Award of the Dean of Humanities and Sciences at Stanford. He has served on the editorial boards of the Journal of Computational and Graphical Statistics, the Journal of the Royal Statistical Society, the Annals of Statistics, the Annals of Applied Statistics, and Statistical Science. He was program co-chair of the 2006 Annual Meeting of the Institute of Mathematical Statistics and served on the executive committee of IMS from 1998 to 2012.
