More Experts


Andrew M. Parker is a senior behavioral and social scientist at the RAND Corporation and a professor within the Pardee RAND Graduate School. His research applies core concepts in behavioral decision research to the understanding of decisions in complex, real-world situations. He has led or contributed to RAND projects on decision quality, risk perception, and individual differences, involving such content domains as health and financial behavior, aging, emergency preparedness and community resilience, climate change, and psychological health. Past projects have addressed low-income consumption decisions, adolescent sexual and contraceptive behavior, retirement planning, drug and alcohol use, expectations for major life events, and public responses to risk information. Parker was principal investigator on a National Science Foundation–funded project validating an adult measure of decisionmaking competence, which has been used to predict major life outcomes. He currently coleads a National Institute of Allergies and Infectious Diseases–funded project examining how influenza and COVID-19 risk perceptions propogate across social networks and influence vaccination decisions. He received a Ph.D. and M.S. in behavioral decision theory and an M.S. in statistics from Carnegie Mellon University, and a B.A. in psychology and statistics from the University of Michigan, Ann Arbor.
