Sally Graglia
Clinical Associate Professor, Emergency Medicine
BioDr. Graglia, the youngest of four in an immigrant family, grew up in Southern California. Considering veterinary medicine, journalism, architecture, and Disney animation, Dr. Graglia ‘discovered people’ during a summer in undergrad working in Ethiopia, decided on medicine as her path forward, and has never looked back.
A UC child, she completed her undergraduate studies at UC Berkeley, medical school at UC Davis, and residency at UCSF with deviations to the Johns Hopkins Bloomberg School of Public Health for a Masters of Public Health and Massachusetts General Hospital (MGH) for fellowship in Emergency Ultrasound.
Having worked, learned, and/or taught throughout Africa, Europe and Eastern Europe, and Central and South America, her three pillars continue to be point-of-care ultrasound (POCUS), education, and global health with an unending drive to serve the underserved.
Outside of work, Dr. Graglia enjoys her growing family, yoga, hiking, being outside, and exploring - new cultures, places, and languages. -

Laura Graham
Other Teaching Staff-Hourly, Surgery
BioI am an epidemiologist and health services researcher with nearly 20 years of experience in surgical outcomes research. My work focuses on improving healthcare delivery and outcomes for Veterans and other vulnerable populations, particularly those who are older or medically complex. Using large administrative datasets from the Veterans Health Administration (VA), I study surgical processes and outcomes to inform system-level improvements.
With postdoctoral training in health economics and implementation science, I bring expertise in causal inference methodology and artificial intelligence, particularly the use of natural language processing (NLP). I apply these methods to extract insights from unstructured clinical data and to strengthen causal analyses in complex healthcare datasets. These approaches allow me to address research questions that were previously difficult to study with standard empirical approaches.
As a collaborative leader, I have mentored junior investigators and worked across academic and industry sectors to advance health services research. My goal is to translate evidence into practice, ultimately improving the quality of surgical care for Veterans. -
Peter Graham
Wells Family Director of the Stanford Institute for Theoretical Physics and Dr. William S. & Carol A. Davies Professor of Physics
Current Research and Scholarly InterestsWhat physics lies beyond the Standard Model and how can we discover it?
Professor Graham is broadly interested in theoretical physics beyond the Standard Model which often involves cosmology, astrophysics, general relativity, and even atomic physics. The Standard Model leaves many questions unanswered including the nature of dark matter and the origins of the weak scale, the cosmological constant, and the fundamental fermion masses. These clues are a guide to building new theories beyond the Standard Model. He recently proposed a new solution to the hierarchy problem which uses dynamical relaxation in the early universe instead of new physics at the weak scale.
Professor Graham is also interested in inventing novel experiments to discover such new physics, frequently using techniques from astrophysics, condensed matter, and atomic physics. He is a proposer and co-PI of the Cosmic Axion Spin Precession Experiment (CASPEr) and the DM Radio experiment. CASPEr uses nuclear magnetic resonance techniques to search for axion dark matter. DM Radio uses high precision magnetometry and electromagnetic resonators to search for hidden photon and axion dark matter. He has also proposed techniques for gravitational wave detection using atom interferometry.
Current areas of focus:
Theory beyond the Standard Model
Dark matter models and detection
Novel experimental proposals for discovering new physics such as axions and gravitational waves
Understanding results from experiments ranging from the LHC to early universe cosmology -

Mark Granovetter
Joan B. Ford Professor, Emeritus
BioMark Granovetter's main interest is in the way people, social networks and social institutions interact and shape one another. He has written extensively on this subject, including his two most widely cited articles "The Strength of Weak Ties" (1973) and "Economic Action and Social Structure: The Problem of Embeddedness" (1985). In recent years, his focus has been on the social foundations of the economy, and he is working on a book entitled Society and Economy, to be published by Harvard University Press in two volumes. The first volume, Society and Economy: Framework and Principles,appeared in 2017. It is broadly theoretical, treating the role in the economy of social networks, norms, culture, trust, power, and social institutions. The second volume will use this framework to illuminate the study of such important topics as corruption, corporate governance, organizational form and the emergence of new industries such as the American electricity industry and the high-tech industry of Silicon Valley.

Giorgio Gratta
Ray Lyman Wilbur Professor
BioGiorgio Gratta is a Professor of Physics at Stanford university. Gratta is an experimentalist, with research interests in the broad area of the physics of fundamental particles and their interactions. While his career started with experiments at particle colliders, since at Stanford Gratta has tackled the study of neutrinos and gravity at the shortest distances.
With two landmark experiments using neutrinos produced by nuclear reactors, Gratta and collaborators investigated the phenomenon of neutrino flavor mixing, in one case reporting the first evidence for neutrino oscillations using artificial neutrinos. This established the finite nature of neutrino masses. The same experiment was also first to detect neutrinos from the interior of our planet, providing a new tool for the Earth sciences.
As a natural evolution from the discovery of neutrino oscillations, Gratta has led the development of liquid Xenon detectors in the search for the neutrinoless double beta decay, an exotic nuclear decay that, if observed, would change our understanding of the quantum nature of neutrinos and help explaining the asymmetry between matter and antimatter in the universe. Gratta is currently the scientific leader of one of the three very large experiments on the subject, world-wide.
In a rather different area of research, Gratta’s group is studying new long range interactions (or an anomalous behavior of gravity) at distances below 50 micrometers. This is achieved with an array of different techniques, from optical levitation of microscopic particles in vacuum, to the use of Mössbauer spectroscopy and, most recently, neutron scattering on nanostructured materials. -

M. Elizabeth Grávalos
Assistant Professor of Anthropology
BioDr. Grávalos is an anthropological archaeologist that studies Indigenous Andean communities in the deep past, for whom we have no written records. She looks at Andean ways of making things—like ceramics, textiles, and cordage—to understand the sociopolitics that undergirded these making practices, including engagements with specific substances and landscapes. With theoretical foci on materiality, ontology, and social practice, this research asks: what are the political affordances of specific materials? How did materials bridge possibilities for political action? How did people’s engagements with specific landscapes and materials impact power dynamics, economies, and social identities? To think through these questions, her work bridges humanities and science perspectives, blending insights from anthropological theory and cultural geography with material science techniques.
Dr. Grávalos’s research is based in the Ancash Region of northern Peru, where her ongoing investigation into political geologies considers how geologic resources are culturally made and valued, and how categorizations and use of these geomaterials foment political dynamics among pre-Hispanic and present-day Andean communities.
Dr. Grávalos is trained as a field archaeologist and materials analysis specialist. Since 2009, she has participated in and directed research projects in Peru, the Bahamas, and the city of Chicago (USA). She is committed to collaboration with descendant communities and centers community-based methodologies in her research. Dr. Grávalos is also an expert in ceramic compositional analysis (LA-ICP-MS and thin section petrography) as well as textile analysis. -
