Dr. Vincent Berardi joined Chapman University in 2017 as an Assistant Professor of Computational Health Psychology within the Crean College of Health and Behavioral Science.  His research lies at the intersection of behavioral science, mathematics, and computational science.  A common theme throughout his work is the recognition that the increasing ubiquity of mobile technology offers the opportunity to observe and intervene upon behavior on a personal level in near real-time. The extensive data generated by such technology, though, requires the development of innovative analytic techniques to model and investigate behavioral systems with an increased level of rigor.  The quality of developed models are increased by incorporating objective principles from behavioral science.   His work has spanned many domains, including secondhand smoke abatement, physical activity promotion, and driving risk reduction.  In each of these cases, machine learning and other novel analytic techniques were applied to intensive longitudinal data with a focus towards assessing and changing behavior in real-time.  He has also collaborated with a group using image processing techniques to assess large databases of commercial magazines in order to infer conclusions about changing societal norms.

Dr. Berardi received his PhD in computational science from Claremont Graduate University.  He also holds an MS in applied mathematics with a concentration in Dynamical Systems from San Diego State University and a B.S in mathematics from St. Peter’s University.

C.B. Phillips, J.C. Hurley, S.S. Angadi, M. Todd, V. Berardi, M.F. Hovell, M.A. Adams. Delay Discount Rate Moderates a Physical Activity Intervention Testing Immediate Rewards. Behavioral Medicine. (In Press). - (IF 1.968, Quartile 2) - The intervention effect for individuals who were paid for meeting physical activity goals was found to be significantly associated with their score on a delay discounting task. This represents an important incorporation of behavioral economics into a health trial.

Parameterizing and Validating Existing Automated Algorithms for Identifying Out-of-Bed Time Using Hip-worn Accelerometer Data from Older Adults. Physiologist Measurement, 40.7 (2019), 075008. - (IF 2.426, Quartile 2) - This research compared three algorithms for calculating in-bed versus out-of-bed time periods for individuals continually wearing accelerometers. Additionally, the best-performing algorithm was incorporated into a public R software library that is now available for other researchers to use.

Rationale, Design, and Baseline Characteristics of WalkIT Arizona: A Factorial Randomized Trial Testing Adaptive Goals and Financial Reinforcement to Increase Walking Across Higher and Lower Walkable Neighborhoods. Contemporary Clinical Trials, 81 (2019), 87-101. - (IF: 2.280, Quartile 1) - This paper described the conceptualization and operationalization of a recently-completed physical activity promotion R-01 trial on which I am a subcontracted co-investigator. Several of the methodologies outlined in this paper were novel responses to the challenges of continually monitoring the physical activity of nearly 500 individuals over the course of a year.

Preventive Medicine Reports, 14 (2019), 100853. - (IF 2.397, Quartile 1) - The work outlined in this paper is reflective of my effort towards leveraging my tobacco control experience into the cannabis domain. The results indicated that the children of parents who reported smoking cannabis in their home had poorer health outcomes than children whose parents did not report indoor cannabis smoking

(In Press). - (IF 5.223, Quartile 1) - This is the main outcomes paper for a recently-completed R-01 that demonstrated the effectiveness of real-time, context-specific feedback in reducing in-home exposure to secondhand smoke. This trial will serve as a foundation from which to base future projects for grant proposals.
