Assistant Professor of Education and, by courtesy, of Computer Science
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.

Along with my Hoover Institution colleague Alvin Rabushka, I developed a framework for equitable and efficient consumption taxation. Our article in the Wall Street Journal in December 1981 was the starting point for an upsurge of interest in consumption taxation. Our book, The Flat Tax (free download from the Hoover Institution Press) spells out the proposal. We were recognized in Money magazine’s Hall of Fame for our contributions to financial innovation.
Marc Lieberman and I have a college textbook, Economics: Principles and Applications, now in its sixth edition.
I also served as director of the research program on economic fluctuations and growth of the National Bureau of Economic Research from 1977 through 2013. I continue to serve as chairman of the Bureau's Committee on Business Cycle Dating, which maintains the semiofficial chronology of the U.S. business cycle.
I have advised a number of government agencies on national economic policy, including the Justice Department, the Treasury Department, the Federal Reserve Board, and the Congressional Budget Office, where I serve on the Advisory Committee. I served on the National Presidential Advisory Committee on Productivity. I have testified on numerous occasions before congressional committees concerning national economic policy.
Before coming to Stanford’s Hoover Institution and the Department of Economics in 1978, I taught at the Massachusetts Institute of Technology and at the University of California, Berkeley. I was born in Palo Alto, attended school there and in Los Angeles, received my B.A. from the University of California, Berkeley, and my Ph.D. from the Massachusetts Institute of Technology.
In a 1976 paper, I introduced the distinction between fresh-water and salt-water economists. Bloggers using these terms are asked to contribute $1 to a fund that sends graduate students to MIT for one year and to the University of Minnesota for a second year.
I am married to economist Susan Woodward, chairman of Sand Hill Econometrics, and live in Menlo Park, California. Visit our blog for pictures and information about our visits to places with villages, ruins, and good food.
MarYam Hamedani, PhD
Managing Director & Senior Research Scientist
BioI am a social psychologist with experience leading centers and teams within higher ed. I study and put into practice strategies to help people live, work, and thrive in today’s increasingly diverse and divided world. My research has been published in peer-reviewed journals, covered by national media outlets, and supported by leading foundations.
As Managing Director and Senior Research Scientist at Stanford SPARQ, I oversee the center’s team and projects. I partner with practitioners in criminal justice, education, economic mobility, education, health, and media to leverage behavioral science insights to drive change. I prioritize an approach to research that is grounded in society’s most pressing problems and centers the perspectives of practitioners working to fight bias and foster diversity, equity, and inclusion on the ground. I create opportunities for researchers and practitioners to learn from one another in mutually beneficial partnerships. I also regularly speak and advise on how social science research on race, culture, and inequality can drive strategies for change.
Before Stanford SPARQ, I was Associate Director of Stanford’s Center for Comparative Studies in Race and Ethnicity (CCSRE) and Stanford's Center for Opportunity Policy in Education (SCOPE). I am a Stanford Ph.D. alum in Social Psychology.

Gabriella M. Harari
Assistant Professor of CommunicationOn Leave from 10/01/2022 To 06/30/2023
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). Her work has also been supported by the National Science Foundation and Stanford HAI Seed Grant Awards.
Assistant Professor of Neurobiology
Current Research and Scholarly InterestsOur laboratory studies the mechanisms by which highly complex behaviors are mediated at the neuronal level, mainly focusing on the example of dynamic social interactions and the neural circuits that drive them. From dyadic interactions to group dynamics and collective decision making, the lab seeks a mechanistic understanding for the fundamental building blocks of societies, such as cooperation, empathy, fairness and reciprocity.
Rosina Pierotti Professor of Italian Literature, Emeritus
BioProfessor Harrison received his doctorate in Romance Studies from Cornell University in 1984, with a dissertation on Dante's Vita Nuova. In 1985 he accepted a visiting assistant professorship in the Department of French and Italian at Stanford. In 1986 he joined the faculty as an assistant professor. He was granted tenure in 1992 and was promoted to full professor in 1995. In 1997 Stanford offered him the Rosina Pierotti Chair of Italian Literature. In 2002, he was named chair of the Department of French and Italian. In 2006 he became a member of the American Academy of Arts & Sciences. In 2014 he was knighted "Chevalier" by the French Republic. He is also lead guitarist for the cerebral rock band Glass Wave.
Professor Harrison's first book, The Body of Beatrice, was published by Johns Hopkins University Press in 1988. The Body of Beatrice was translated into Japanese in 1994. Over the next few years Professor Harrison worked on his next book, Forests: The Shadow of Civilization, which appeared in 1992 with University of Chicago Press. This book deals with the multiple and complex ways in which the Western imagination has symbolized, represented, and conceived of forests, primarily in literature, religion, and mythology. It offers a select history that begins in antiquity and ends in our own time. Forests appeared simultaneously in English, French, Italian, and German. It subsequently appeared in Japanese and Korean as well. In 1994 his book Rome, la Pluie: A Quoi Bon Littérature? appeared in France, Italy, and Germany. This book is written in the form of dialogues between two characters and deals with various topics such as art restoration, the vocation of literature, and the place of the dead in contemporary society. Professor Harrison's next book, The Dominion of the Dead, published in 2003 by University of Chicago Press, deals with the relations the living maintain with the dead in diverse secular realms. This book was translated into German, French and Italian. Professor Harrison's book Gardens: An Essay on the Human Condition appeared in 2008 with the University of Chicago Press, and in French with Le Pommier (subsequently appeared in German and Chinese translations). His most recent book Juvenescence: A Cultural History of Our Age came out in 2014 with Chicago University Press. In 2005 Harrison started a literary talk show on KZSU radio called "Entitled Opinions." The show features hour long conversations with a variety of scholars, writers, and scientists.

She is currently working with BVHPCA and other partners to develop knowledge infrastructures to underpin community-driven public history that supports racial equity and environmental justice.
Hecht’s 2012 book Being Nuclear: Africans and the Global Uranium Trade offers new perspectives on the global nuclear order by focusing on African uranium mines and miners. It received awards from the Society for the Social Studies of Science, the American Historical Association, the American Sociological Association, and the Suzanne M. Glasscock Humanities Institute, as well as an honorable mention from the African Studies Association. An abridged version appeared in French as Uranium Africain, une histoire globale (Le Seuil 2016), and a Japanese translation is due out in 2021. Her first book, The Radiance of France: Nuclear Power and National Identity (1998/ 2nd ed 2009), explores how the French embedded nuclear policy in reactor technology, and nuclear culture in reactor operations. It received awards from the American Historical Association and the Society for the History of Technology, and has appeared in French as Le rayonnement de la France: Énergie nucléaire et identité nationale après la seconde guerre mondiale (2004/ 2014).
Her affiliations at Stanford include the Center for African Studies, the Program in Science, Technology, and Society, the Center for Global Ethnography, the Program on Urban Studies, and the Program in Modern Thought and Literature. Before rejoining Stanford in 2017, Hecht taught at the University of Michigan’s History department for 18 years. She helped to found and direct UM’s Program in Science, Technology, and Society (STS). She served as associate director of UM’s African Studies Center, and participated in its long-term collaboration with the Wits Institute for Social and Economic Research (South Africa). She has supervised dissertations in STS, African history and anthropology, nuclear studies, and French history.
Hecht holds a PhD in History and Sociology of Science from the University of Pennsylvania (1992), and a bachelor’s degree in Physics from MIT (1986). She’s been a visiting scholar in universities in Australia, France, the Netherlands, Norway, South Africa, and Sweden. Her work has been funded by the National Science Foundation, the National Endowment for the Humanities, the American Council for Learned Societies, and the South African and Dutch national research foundations, among others.

Professor of Electrical Engineering, Emeritus
BioMartin E. Hellman is Professor Emeritus of Electrical Engineering at Stanford University and is affiliated with the university's Center for International Security and Cooperation (CISAC). His most recent work, "Rethinking National Security," identifies a number of questionable assumptions that are largely taken as axiomatic truths. A key part of that work brings a risk informed framework to a potential failure of nuclear deterrence and then finds surprising ways to reduce the risk. His earlier work included co-inventing public key cryptography, the technology that underlies the secure portion of the Internet. His many honors include election to the National Academy of Engineering and receiving (jointly with his colleague Whit Diffie) the million dollar ACM Turing Award, the top prize in computer science. In 2016, he and his wife of fifty years published "A New Map for Relationships: Creating True Love at Home & Peace on the Planet," providing a “unified field theory” for peace by illuminating the connections between nuclear war, conventional war, interpersonal war, and war within our own psyches.

Associate Professor (Teaching) of PhilosophyOn Leave from 10/01/2022 To 06/30/2023
BioI did my undergraduate work at Amherst and went on to graduate school at Princeton. Since then I've taught at Harvard, UCLA, The University of Pennsylvania, The University of Michigan, Berkeley, and Stanford. I resumed my graduate career a little while back -- from a distance, as it were -- receiving the PhD in 2005.
I'm married to another philosopher, Krista Lawlor.
My interests continue to center in aesthetics, but they have spilled over into pretty much every branch of philosophy at one time or another.
Wittgenstein, Culture and Value, 34: Im Rennen der Philosophie gewinnt, wer am langsamsten laufen kann. Oder: der, der das Ziel zuletzt erreicht. (In philosophy the race is to the one who can run slowest — the one who crosses the finish line last.) I'm not sure I believe this, but it's a comforting thing to read.
