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).

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.
