Dary Fiorentino’s professional interests are grouped in three broad categories: conducting research, teaching, and providing expert testimony in legal cases.

His primary research areas of interest include 1) the effects of age on a variety of physiological, sensory, perceptual, and cognitive dimensions, 2) standardized field sobriety tests, 3) alcohol pharmacokinetics and pharmacodynamics, 4) cultural differences in drinking and drinking and driving, 5) fitness-for-duty and workplace alcohol and drug testing, and 6) life satisfaction and human flourishing, including life-workplace balance.

He is an Assistant Professor in the Department of Organizational Psychology at Alliant International University Los Angeles, where he teaches classes in research methods and statistics. He particularly enjoys teaching topics in multiple regression, moderation and mediation, and structural equation modeling. He is also Adjunct Faculty at Pepperdine University. Dr. Fiorentino has a profound belief in the usefulness of the scientific method to explore human issues, and that psychologists are uniquely equipped to study and positively affect many aspects of the human experience, provided they have the methodological and analytical skills to do so. He takes pride in providing some of those skills to his students.

Dr. Fiorentino provides expert testimony in legal cases in which alcohol and/or some drugs are suspected to have contributed to one or more adverse events. His testimony usually focuses on the relationships between alcohol dose and blood alcohol concentration (BAC), BAC and driving impairment, and driving impairment and crash risk.

He earned a B.A. in Psychology and an M.A. in Human Factors, both from California State University Northridge, and a Ph.D. in Cognitive Psychology from Claremont Graduate University.
