Savas Dimopoulos
Hamamoto Family Professor
BioWhat is the origin of mass? Are there other universes with different physical laws?
Professor Dimopoulos has been searching for answers to some of the deepest mysteries of nature. Why is gravity so weak? Do elementary particles have substructure? What is the origin of mass? Are there new dimensions? Can we produce black holes in the lab?
Elementary particle physics is entering a spectacular new era in which experiments at the Large Hadron Collider at CERN will soon shed light on such questions and lead to a new deeper theory of particle physics, replacing the Standard Model proposed forty years ago. The two leading candidates for new theories are the Supersymmetric Standard Model and theories with Large Extra Dimensions, both proposed by Professor Dimopoulos and collaborators.
Professor Dimopoulos is collaborating on a number of experiments that use the dramatic advances in atom interferometry to do fundamental physics. These include testing Einstein’s theory of general relativity to fifteen decimal precision, atom neutrality to thirty decimals, and looking for modifications of quantum mechanics. He is also designing an atom-interferometric gravity-wave detector that will allow us to look at the universe with gravity waves instead of light, marking the dawn of gravity wave astronomy and cosmology. -

José R. Dinneny
Professor of Biology
Current Research and Scholarly InterestsThe biology of root systems is governed by both micro-scale and systemic signaling that allows the plant to integrate these complex variables into growth and branching decisions that ultimately determine the efficiency resources are captured. Research in my lab is aimed at understanding the response of roots to water-limiting conditions and is exploring this process at different organizational scales from the individual cell type to the level of the whole plant.

Sibyl Diver
Lecturer, Earth Systems Program
Affiliate, Bill Lane Center for the American WestBioDr. Sibyl Diver is an interdisciplinary environmental scientist, a lecturer at Stanford University in the Earth Systems Program, and co-director for the Stanford Environmental Justice Working Group. She does community-engaged research on Indigenous water governance from an allied perspective, focusing on Pacific Northwest salmon watersheds. This includes research on co-management (or collaborative management) arrangements between Indigenous communities and state agencies. She received her PhD from Berkeley's Department of Environmental Science, Policy and Management, where she helped build the Karuk-UC Berkeley Collaborative, a group supporting the Karuk Tribe's eco-cultural revitalization strategy in Northern California. Current work includes conducting a social impact assessment of Klamath dam removal with the Karuk Tribe.
For over two decades, Sibyl has worked in partnership with community leaders on issues of Indigenous peoples and salmon around the North Pacific – in the Russian Far East, Alaska, Canada and the US. Previous to graduate school, she spent eight years doing international conservation work and facilitating international exchanges with community leaders as a Russian translator -- an experience that introduced her to the deep connections between salmon conservation and Indigenous peoples. She completed her undergraduate work at Stanford, earning a dual degree in Human Biology and Slavic Studies.

Scott Dixon
Professor of Biology
Current Research and Scholarly InterestsMy lab is interested in the relationship between cell death and metabolism. Using techniques drawn from many disciplines my laboratory is investigating how perturbation of intracellular metabolic networks can result in novel forms of cell death, such as ferroptosis. We are interested in applying this knowledge to find new ways to treat diseases characterized by insufficient (e.g. cancer) or excessive (e.g. neurodegeneration) cell death.

Rowan Dorin
Associate Professor of History
BioI am a historian of western Europe and the Mediterranean, primarily during the high and late Middle Ages. Much of my research tries to understand how law and society interact with each other, especially where legal norms conflict with social practices. Another strand of my research explores the history of economic life and economic thought, especially medieval debates over usury and moneylending. I have also written on the circulation of goods, people, and ideas in the medieval Mediterranean.
My recent book (No Return: Jews, Christian Usurers, and the Spread of Mass Expulsion in Medieval Europe, Princeton University Press, 2023) uses the banishment of Jewish and Christian moneylenders to explore the rise of mass expulsion as a widespread practice in the later Middle Ages. A second ongoing project examines the ways in which medieval canon law was adapted, reinterpreted, or resisted in local contexts in the thirteenth and fourteenth centuries. The latter builds on Corpus Synodalium, a prize-winning full-text database of late medieval local ecclesiastical legislation that I have been developing since 2016, with assistance from colleagues around the world.
Born and raised in western Canada, I did my undergraduate and doctoral work at Harvard University, earning an MPhil in Medieval History from the University of Cambridge along the way. Before coming to Stanford, I was a Junior Fellow at the Harvard Society of Fellows. -

Justin Du Bois
Henry Dreyfus Professor of Chemistry and Professor, by courtesy, of Chemical and Systems Biology
BioThe Du Bois lab is heavily invested in exploring voltage-gated ion channel function and physiology and the underlying role of specific channels in human pathologies, particularly nociception, epilepsy, and neurodevelopmental disorders. With expertise in chemical synthesis, we have access to a collection of exceptional natural products—tetrodotoxin, saxitoxin, gonyautoxin, batrachotoxin, veratridine, antillatoxin, to name a few—that act as selective modulators of sodium ion channels (NaVs). In addition, we have developed novel molecules as inhibitors and agonists of specific voltage-gated chloride (ClCs) and calcium (CaVs) channel isoforms. As a lab, we are uniquely positioned to advance high-precision chemical tools to interrogate underlying biochemical mechanisms of electrogenesis. Our work in this arena is guided by a number of questions related to the basic functioning of voltage-gated channels in neuronal cells and glia that include: 1) what is the rate at which channels are being made and degraded and is the rate of channel turnover context dependent (i.e., is protein turnover affected by increased neuronal activity, nerve cell damage, etc.); 2) to what extent is channel expression and cellular distribution affected by external factors (pH, inflammatory modulators, injury); 3) how do post-translational protein modifications influence channel function and how are such modifications altered in response to external factors; 4) how do neighboring glia influence channel expression and ion gating. Answers to these types of questions will provide a deeper understanding of the molecular mechanisms by which neuronal cells and tissue respond to external stimuli, stress, and injury. We benefit from the strong interest of others in our work and multiple collaborators at Stanford and at other institutions.
Ion channel function and physiology. We wish to understand the role of individual subtypes of voltage-gated sodium, chloride, and calcium channels in neuronal signaling and how structural changes (i.e., point mutations, post-translational modifications, partner proteins) alter channel function. Our interests include the design, development, and application of chemogenetic technologies for targeting individual channel subtypes and allosteric modulators of select channel isoforms. Our work aims to inform efforts in translational research, as voltage-gated ion channel dysregulation and malfunction underlie a wide range of human diseases and disorders.
Natural products synthesis. We are interested in developing efficient and flexible synthetic routes to natural products that serve as ‘lead’ compounds for advancing high precision pharmacological tools. Most of the targets we are interested in obtaining are not available in sufficient quantities from natural sources, thus necessitating de novo preparation. To streamline the assembly process of these complex molecules, we are challenged to develop, in parallel, new tactics and chemical methods that facilitate C–C, C–N, and C–O bond formation.
Toxin ‘sponge’ proteins. A longstanding collaboration with the Minor lab at UCSF has focused on understanding how certain organisms that ingest dietary toxins such as saxitoxin, tetrodotoxin, and batrachotoxin survive their poisonous effects. This work has resulted in the elucidation of the structures of novel paralytic shellfish-binding proteins (so-called saxiphilins) and the toxin ‘binding code’. Studies are ongoing to integrate saxiphilins into a diagnostic device for measuring toxin concentrations in shellfish and to advance an engineered toxin-binding protein as a countermeasure for paralytic shellfish poisoning.
