Nicholas Haber
Assistant Professor of Education
Current Research and Scholarly InterestsI use AI models of of exploratory and social learning in order to better understand early human learning and development, and conversely, I use our understanding of early human learning to make robust AI models that learn in exploratory and social ways. Based on this, I develop AI-powered learning tools for children, geared in particular towards the education of those with developmental issues such as the Autism Spectrum Disorder and Attention Deficit Hyperactivity Disorder, in the mold of my work on the Autism Glass Project. My formal graduate training in pure mathematics involved extending partial differential equation theory in cases involving the propagation of waves through complex media such as the space around a black hole. Since then, I have transitioned to the use of machine learning in developing both learning tools for children with developmental disorders and AI and cognitive models of learning.

Stephen Haber
A.A. and Jeanne Welch Milligan Professor, Senior Fellow at the Hoover Institution and at the Stanford Institute for Economic Policy Research, Professor of History and, by courtesy, of Economics
BioStephen Haber is the A.A. and Jeanne Welch Milligan Professor in the School of Humanities and Sciences at Stanford University, the Peter and Helen Bing Senior Fellow at the Hoover Institution, and senior fellow at the Stanford Institute for Economic Policy Research. In addition, he is a professor of political science, professor of history, and professor of economics (by courtesy).
Haber has spent his career investigating why the world distribution of income so uneven. His papers have been published in economics, history, political science, and law journals.
He is the author of five books and the editor of six more. Haber’s most recent books include Fragile by Design with Charles Calomiris (Princeton University Press), which examines how governments and industry incumbents often craft banking regulatory policies in ways that stifle competition and increase systemic risk. The Battle Over Patents (Oxford University Press), a volume edited with Naomi Lamoreaux, documents the development of US-style patent systems and the political fights that have shaped them.
His latest project focuses on a long-standing puzzle in the social sciences: why are prosperous democracies not randomly distributed across the planet, but rather, are geographically clustered? Haber and his coauthors answer this question by using geospatial tools to simulate the ecological conditions that shaped pre-industrial food production and trade. They then employ machine learning methods to elucidate the relationship between ecological conditions and the levels of economic development that emerged across the globe over the past three centuries.
Haber holds a Ph.D. in history from UCLA and has been on the Stanford faculty since 1987.
From 1995 to 1998, he served as associate dean for the social sciences and director of Graduate Studies of Stanford’s School of Humanities and Sciences. He is among Stanford’s most distinguished teachers, having been awarded every teaching prize Stanford has to offer. -

Gabriella M. Harari
Assistant Professor of Communication
BioGabriella Harari is an Assistant Professor in the Department of Communication at Stanford University, where she directs the Media and Personality Lab.
She studies how personality is expressed in the physical and digital contexts of everyday life. Much of her research is focused on understanding what digital technologies reveal about who we are, and how use of digital technologies shapes who we are. Her current projects analyze people’s everyday behavioral patterns (e.g., social interactions, mobility) and environmental contexts (e.g., places visited, social media platforms) to show how they are associated with individual differences in personality and well-being.
Harari takes an ecological approach to conducting her research, emphasizing the importance of studying people and their behavior in natural contexts. To that end, she conducts intensive longitudinal field studies and is interested in mobile sensing methods and analytic techniques that combine approaches from the social and computer sciences. For example, methodologies she uses in her work in include surveys, experience sampling, longitudinal modeling, mobile sensing, data mining, and machine learning.
Harari completed a Postdoctoral Fellowship and earned her PhD at the Department of Psychology at The University of Texas at Austin. She completed her BA in Psychology & Humanities from Florida International University, where she was also a Ronald E. McNair Scholar. Her work has been published in academic outlets such as Perspectives in Psychological Science, Journal of Personality and Social Psychology, and the Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies (IMWUT).

James Harris
James and Elenor Chesebrough Professor in the School of Engineering, Emeritus
BioHarris utilizes molecular beam epitaxy (MBE) of III-V compound semiconductor materials to investigate new materials for electronic and optoelectronic devices. He utilizes heterojunctions, superlattices, quantum wells, and three-dimensional self-assembled quantum dots to create metastable engineered materials with novel or improved properties for electronic and optoelectronic devices. His early work in the 1970's demonstrating a practical heterojunction bipolar transistor led to their application in every mobile phone today and record setting solar cell efficiency. He has recently focused on three areas: 1) integration of photonic devices and micro optics for creation of new minimally invasive bio and medical systems for micro-array and neural imaging and 2) application of nanostructures semiconductors for the acceleration of electrons using light, a dielectric Laser Accelerator (DLA), and 3) novel materials and nano structuring for high efficiency solar cells and photo electrochemical water splitting for the generation of hydrogen.

Sean Hartnoll
Principal Investigator, Stanford Institute for Materials and Energy Sciences
BioI am a theorist working on problems in gravitational, high energy and condensed matter physics. In recent years the holographic correspondence, the physics of quantum entanglement and quantum field theory more generally have led to strong connections between central concerns in these different fields.
For example, I am interested in understanding the emergence of spacetime from large N matrix quantum mechanics models. These can be thought of as the simplest models of holographic duality, and will likely hold the key to understanding the emergence of local physics as well as black holes. The most basic object in these theories is the ground state wavefunction. Understanding this wavefunction is a many-body problem and I am interested in using modern ideas from condensed matter theory -- such as topological order -- to characterize it.
Another example has to do with dissipation. How quickly can a quantum mechanical system thermalize itself? From this perspective, there are remarkable similarities between strongly quantum mechanical systems such as the quark-gluon plasma and high temperature superconductors and the dynamics of black holes in classical gravity. This may suggest that a fundamental limitation imposed by quantum statistical mechanics is at work in these systems. I have pursued this possibility from many angles, including variational principles for entropy production, the Lieb-Robinson bound on velocities in quantum systems and bounds on the magnitude of quantum fluctuations near thermal equilibrium.
In parallel to a ''bird's eye'' approach to quantum statistical mechanics, I am also increasingly interested in specific scattering mechanisms in unconventional materials that may give a relatively simple explanation of transport behavior that has otherwise been considered anomalous --- using this approach my collaborators and I have 'demystified' aspects of transport in quantum critical ruthenate materials. I am currently interested, for example, in the role of phonons in strongly correlated electronic systems.
I have recently worked on black hole interiors in classical gravity. Black hole interiors are extremely rich mathematically, but their physical interpretation -- for example in a holographic context -- remains obscure. To start to address this question I have shown how important dynamics of the interior, such as the instability of the singularity and of Cauchy horizons, can be triggered in a relatively simple holographic setting.

Melanie Hayden Gephart
Professor of Neurosurgery and, by courtesy, of Neurology
BioI am a brain tumor neurosurgeon, treating patients with primary and metastatic brain tumors. I treat patients with malignant and benign tumors, including glioma, brain metastases, meningioma, and vestibular schwannomas. I direct the Stanford Brain Tumor Center and the Stanford Brain Metastasis Consortium, collaborative unions of physicians and scientists looking to improve our understanding and treatment of brain tumors. My laboratory seeks greater understanding of the mechanisms driving tumorigenesis and disease progression in malignant brain tumors. We study how rare cancer cell populations survive and migrate in the brain, inadvertently supported by native brain cells. We develop novel cell free nucleic acid biomarkers to track brain cancer treatment response, relapse, and neurotoxicity. Our bedside-to-bench-to-bedside research model builds on a foundation of generously donated patient samples, where we test mechanisms of brain cancer growth, develop novel pre-clinical models that reliably recapitulate the human disease, and facilitate clinical trials of new treatments for patients with brain cancer.

Shea Hess Webber
Physical Science Research Scientist
Bio***EDUCATION:***
Dr. Hess Webber received a BS in Physics from Gettysburg College in 2009. She subsequently joined the Computational Data Sciences PhD program (formerly, Computational Science and Informatics) at George Mason University, with a specialty in Astrophysics and Space Sciences. Her PhD thesis work was entitled "Solar f-mode Wave Scattering Off Linear Source Boundaries" and she successfully completed her PhD in late 2016 (also earning an MS along the way -- 2012).
***EXPERIENCE:***
Dr. Hess Webber began her career in solar physics research in 2005, as a summer intern in the Solar Physics Division at NASA's Goddard Space Flight Center. She continued collaborating with scientists at Goddard through undergrad, mainly working in solar coronal hole studies using SOHO/EIT data but also collaborating briefly on solar flare studies with the RHESSI team. She began working at GSFC full-time as a graduate research assistant in 2009. Her initial GRA work continued the ongoing coronal hole detection research, extending the data set with SDO/AIA images and improving the detection technique. The core of Dr. Hess Webber's dissertation considered coronal holes using helioseismology, investigating how surface waves on the Sun are influenced when passing through a coronal hole and whether wave perturbations can be used to isolate coronal hole boundaries. In doing so, she developed a new geometry-dependent helioseismic technique and showed that the geometry of a "scattering feature" is non-negligible in helioseismology studies. After defending her PhD, Dr. Hess Webber continued as a contracted postdoctoral researcher at GSFC for a year, collaborating on CME-tracking methods. In early 2018, she began as a postdoctoral scholar at Stanford University in the W. W. Hansen Experimental Physics Lab's solar physics group. Currently, Dr. Hess Webber is continuing as research staff with the HEPL solar physics team, where her main research projects include helioseismic studies, and machine-learning applied to solar magnetism to enable improved coronal/solar-wind models for space-weather forecasting.
***LEADERSHIP:***
Dr. Hess Webber is currently an elected member of the AAS Solar Physics Division Committee. She is also a co-lead of the COFFIES Center Effectiveness Team.
***BROADER IMPACTS***
Dr. Hess Webber also has extensive experience with Education and Public Outreach in solar physics, and some experience with science policy. She is currently on the KIPAC Equity & Inclusion Task Forces for 1) Mental Health and 2) Mentoring. She also actively participates in the COFFIES DEIA and Beans initiatives, as well as organizes the Stanford Solar Physics Summer Student program. -

Keith Hodgson
David Mulvane Ehrsam and Edward Curtis Franklin Professor of Chemistry and Professor of Photon Science at SLAC
BioCombining inorganic, biophysical and structural chemistry, Professor Keith Hodgson investigates how structure at molecular and macromolecular levels relates to function. Studies in the Hodgson lab have pioneered the use of synchrotron x-radiation to probe the electronic and structural environment of biomolecules. Recent efforts focus on the applications of x-ray diffraction, scattering and absorption spectroscopy to examine metalloproteins that are important in Earth’s biosphere, such as those that convert nitrogen to ammonia or methane to methanol.
Keith O. Hodgson was born in Virginia in 1947. He studied chemistry at the University of Virginia (B.S. 1969) and University of California, Berkeley (Ph.D. 1972), with a postdoctoral year at the ETH in Zurich. He joined the Stanford Chemistry Department faculty in 1973, starting up a program of fundamental research into the use of x-rays to study chemical and biological structure that made use of the unique capabilities of the Stanford Synchrotron Radiation Lightsource (SSRL). His lab carried out pioneering x-ray absorption and x-ray crystallographic studies of proteins, laying the foundation for a new field now in broad use worldwide. In the early eighties, he began development of one of the world's first synchrotron-based structural molecular biology research and user programs, centered at SSRL. He served as SSRL Director from 1998 to 2005, and SLAC National Accelerator Laboratory (SLAC) Deputy Director (2005-2007) and Associate Laboratory Director for Photon Science (2007-2011).
Today the Hodgson research group investigates how molecular structure at different organizational levels relates to biological and chemical function, using a variety of x-ray absorption, diffraction and scattering techniques. Typical of these molecular structural studies are investigations of metal ions as active sites of biomolecules. His research group develops and utilizes techniques such as x-ray absorption and emission spectroscopy (XAS and XES) to study the electronic and metrical details of a given metal ion in the biomolecule under a variety of natural conditions.
A major area of focus over many years, the active site of the enzyme nitrogenase is responsible for conversion of atmospheric di-nitrogen to ammonia. Using XAS studies at the S, Fe and Mo edge, the Hodgson group has worked to understand the electronic structure as a function of redox in this cluster. They have developed new methods to study long distances in the cluster within and outside the protein. Studies are ongoing to learn how this cluster functions during catalysis and interacts with substrates and inhibitors. Other components of the protein are also under active study.
Additional projects include the study of iron in dioxygen activation and oxidation within the binuclear iron-containing enzyme methane monooxygenase and in cytochrome oxidase. Lab members are also investigating the role of copper in electron transport and in dioxygen activation. Other studies include the electronic structure of iron-sulfur clusters in models and enzymes.
The research group is also focusing on using the next generation of x-ray light sources, the free electron laser. Such a light source, called the LCLS, is also located at SLAC. They are also developing new approaches using x-ray free electron laser radiation to image noncrystalline biomolecules and study chemical reactivity on ultrafast time scales. -

David S. Hong
Associate Professor of Psychiatry and Behavioral Sciences (Interdisciplinary Brain Science Research)
Current Research and Scholarly InterestsDr. Hong is a child and adolescent psychiatrist and clinician-scientist. His responsibilities span clinical care, teaching/mentorship, and research, with a unifying theme of advancing a developmental cognitive framework as applied to psychiatric conditions. Using this core premise, he work encompasses multiple domains: specialized clinical care, fellowship training, research mentorship, and elaborating the role of sex-specific determinants of development, one of the greatest contributors to individual developmental variation.
His lab investigates genetic and hormonal influences underlying sex differences in child psychiatric conditions. Sex has emerged as a critical variable driving differences in the phenomenology, course, and treatment of many mental health disorders. Unfortunately, an understanding of the biological mechanisms driving these effects are limited. By applying innovative neuroimaging and multiomic approaches, Dr. Hong seeks to provide a deeper understanding of the connection between sex-specific effects and complex psychiatric diseases. To do so, research in the Hong Lab focuses on the role of genes on the X and Y chromosomes, as well as circulating sex hormones on brain development, cognition, and behavior. The lab broadly aims to elucidate the changing nature of these mechanisms across various stages of development.
Another area of focus is the implementation of clinical informatics in child psychiatry and the development of digital mental health tools. As co-Director of the Mental Health Technology and Innovation Hub, Dr. Hong is helping to develop clinical and research infrastructure within the Department of Psychiatry and Behavioral Sciences to advance development of mobile mental health resources that will improve efficacy and access to mental health care. -

Michael R. Howitt
Assistant Professor of Pathology and of Microbiology and Immunology
Current Research and Scholarly InterestsOur lab is broadly interested in how intestinal microbes shape our immune system to promote both health and disease. Recently we discovered that a type of intestinal epithelial cell, called tuft cells, act as sentinels stationed along the lining of the gut. Tuft cells respond to microbes, including parasites, to initiate type 2 immunity, remodel the epithelium, and alter gut physiology. Surprisingly, these changes to the intestine rely on the same chemosensory pathway found in oral taste cells. Currently, we aim to 1) elucidate the role of specific tuft cell receptors in microbial detection. 2) To understand how protozoa and bacteria within the microbiota impact host immunity. 3) Discover how tuft cells modulate surrounding cells and tissue.

Andrew D. Huberman
Associate Professor of Neurobiology and, by courtesy, of Psychiatry and Behavioral Sciences
Current Research and Scholarly InterestsIn 2017, we developed a virtual reality platform to investigate the neural and autonomic mechanisms contributing to fear and anxiety. That involved capturing 360-degree videos of various fear-provoking situations in real life for in-lab VR movies, such as heights and claustrophobia, as well as unusual scenarios like swimming in open water with great white sharks. The primary objective of our VR platform is to develop new tools to help people better manage stress, anxiety and phobias in real-time, as an augment to in-clinic therapies.
In May 2018, we reported the discovery of two novel mammalian brain circuits as a Research Article published in Nature. One circuit promotes fear and anxiety-induced paralysis, while the other fosters confrontational reactions to threats. This led to ongoing research into the involvement of these brain regions in anxiety-related disorders such as phobias and generalized anxiety in humans.
In 2020, we embarked on a collaborative effort with Dr. David Spiegel's laboratory in the Stanford Department of Psychiatry and Behavioral Sciences, aimed to explore how specific respiration patterns synergize with the visual system to influence autonomic arousal and stress, and other brain states, including sleep.
In 2023, the first results of that collaboration were published as a randomized controlled trial in Cell Reports Medicine, demonstrating that specific brief patterns of deliberate respiration are particularly effective in alleviating stress and enhancing mood, and improving sleep.
In a 2021, our collaboration with Dr. Edward Chang, professor and chair of the Department of Neurological Surgery at the University of California, San Francisco (UCSF), was published in Current Biology, revealing that specific patterns of insular cortex neural activity may be linked to, and potentially predict, anxiety responses. -
