Boker serves as a professor of quantitative psychology as well as a professor of data science by courtesy. He directs the Ph.D. program in quantitative psychology, the Human Dynamics Laboratory, and the LIFE Academy at the University of Virginia. He is known internationally as an expert in modeling longitudinal data from a dynamical systems perspective.
Boker's work also focuses on measuring and modeling the dynamics of dyadic conversation, age-related changes in resiliency as indicated by coupled dynamics between stress and affect, coupled dynamics between mothers and infants, and adaptive dynamic models for addiction. Boker is a fellow of the American Psychological Association and the Association for Psychological Science.
