Jon Krosnick
Frederic O. Glover Professor of Humanities and Social Sciences, Professor of Communication and of Political Science, of Environmental Social Sciences and, by courtesy, of Psychology
BioJon Krosnick is a social psychologist who does research on attitude formation, change, and effects, on the psychology of political behavior, and on survey research methods. He is the Frederic O. Glover Professor in Humanities and Social Sciences, Professor of Communication, Political Science, Environmental Social Sciences, and (by courtesy) Psychology. He directs Stanford's Political Psychology Research Group and has directed the Summer Institute in Political Psychology.

Research Interests
Author of seven published books and two forthcoming books and more than 190 articles and chapters, Dr. Krosnick conducts research in three primary areas: (1) attitude formation, change, and effects, (2) the psychology of political behavior, and (3) the optimal design of questionnaires used for laboratory experiments and surveys, and survey research methodology more generally.
His attitude research has focused primarily on the notion of attitude strength, seeking to differentiate attitudes that are firmly crystallized and powerfully influential of thinking and action from attitudes that are flexible and inconsequential. Many of his studies in this area have focused on the amount of personal importance that an individual chooses to attach to an attitude. Dr. Krosnick’s studies have illuminated the origins of attitude importance (e.g., material self-interest and values) and the cognitive and behavioral consequences of importance in regulating attitude impact and attitude change processes.
Honors
Winner of the American Association for Public Opinion Research’s Lifetime Achievement Award for outstanding research, and the Nevitt Sanford Award from the International Society of Political Psychology, Dr. Krosnick’s scholarship has been recognized by election as a fellow by the American Academy of Arts and Sciences and by the American Association for the Advancement of Science, the Erik Erikson Award for Excellence and Creativity in the Field of Political Psychology from the International Society of Political Psychology, two fellowships at the Center for Advanced Study in the Behavioral Sciences, the Phillip Brickman Memorial Prize for Research in Social Psychology, and the American Political Science Association’s Best Paper Award. -
Chirag Kumar
Ph.D. Student in Environment and Resources, admitted Autumn 2025
BioChirag Kumar combines next-generation modeling tools with on-the-ground field research to provide actionable strategies that improve human health amidst environmental and migratory uncertainty. He is interested in causally unraveling the environmental factors driving infectious diseases to inform targeted interventions that mitigate those threats and how those insights can be directly shared with the public to empower individual-level change. To unravel complex human-environment-health systems, he has conducted on-the-ground field work and mechanistic biological analyses to provide key inputs into his models. His findings have been used to advocate for new World Health Organization vaccine recommendations against antimicrobial-resistant pathogens. Chirag previously served as a Biden-Harris US Digital Corps Data Fellow at the US CDC’s Center for Forecasting and Outbreak Analytics and on the Biden administration’s White House AI Forum. He graduated from Princeton University as a Smith-Newton Environmental Research Scholar where he concentrated in chemistry with minors in applied math, global health, and quantitative biology. He is supported by a National Science Foundation Graduate Research Fellowship.

Angelle Desiree LaBeaud
Professor of Pediatrics (Infectious Diseases), Senior Fellow at the Woods Institute for the Environment and Professor, by courtesy, of Epidemiology and Population Health and of Environmental Social Sciences
Current Research and Scholarly InterestsArthropod-borne viruses are emerging and re-emerging infections that are spreading throughout the world. Our laboratory investigates the epidemiology of arboviral infections, focusing on the burden of disease and the long-term complications on human health. In particular, Dr. LaBeaud investigates dengue, chikungunya, and Rift Valley fever viruses in Kenya, where outbreaks cause fever, arthritis, retinitis, encephalitis, and hemorrhagic fever. Our main research questions focus on the risk factors for arboviral infections, the development of diagnostic tests that can be administered in the field to quickly determine what kind of arboviral infection a person has, and the genetic and immunologic investigation of why different people respond differently to the same infection. Our long-term goals are to contribute to a deeper understanding of arboviral infections and their long-term health consequences and to optimize control strategies to prevent these emerging infections. Our laboratory also investigates the effects of antenatal and postnatal parasitic infections on vaccine responses, growth, and development of Kenyan children.
My lab at Stanford supports the field work that is ongoing in Kenya, but we also have several projects that are based locally. We strive to improve diagnostics of arboviral infections and are using Luminex technology to build a new screening assay. We also have created a Luminex based platform to assess vaccine responses against multiple pathogens.
