Associate Professor - Quantitative Psychology Program
Prevention Methodology, Health Behavior Change, Health Risk Behaviors, Mental Health
I am an Associate Professor in the Department of Psychology within the quantitative Psychology emphasis. With training in human development and prevention methodology, my research is driven by two primary goals: 1) Understand the development of health risk behavior across adolescence and adulthood; 2) Develop, test, and apply statistical methods designed to characterize effects in prevention and intervention studies. In my ongoing research of adolescents' health behavior, I have examined how contextual transitions contribute to changes in trajectories of health risk behaviors, including substance use, delinquent behavior, and risky sexual activity. Related to this work, I am currently exploring how adolescents' health behaviors change in conjunction with social environmental changes.
My methodological work focuses on identifying and testing statistical strategies for improving the estimation of models applicable to prevention science. I am currently working with colleagues at USU and other universities to improve estimation techniques of indirect, or mediated effects for prevention and intervention studies. Additional quantitative areas of interest include complex mixture modeling and integrating theories of health behavior change with statistical methods.
