Summary

I’m a methodologist using advanced statistical modelling to better understand the role of the environment on health-related outcomes. Much of my work has been in substance use, primarily alcohol and tobacco, with a focus on population-level prevention. Recent alcohol projects have included examining the relationships between alcohol outlet density and crime, seeing how a state’s alcohol policy environment and enforcement relate to things such as alcohol consumption, traffic crashes, and mortality, developing and testing a manager-focused alcohol retailer training program, and developing new techniques for preventing alcohol-related problems on college campuses. This alcohol work is in close collaboration with my colleagues in the Alcohol Epidemiology Program, located in the Division of Epidemiology & Community Health. 

Other work focuses on obesity and HIV/AIDS, including prevention methodology and intervention.

Research Summary/Interests

The models we use tend to be complex, mostly to overcome data and study design constraints. First, correlation exists in almost all of our datasets, and I use a number of statistical models to accommodate this correlation including random intercept models, correlated residual models, random coefficient/growth curve models, general estimating equations, and time series, to name a few. Second, recent work has involved the use of tailored or SMART designs. These study designs complement traditional RCT designs and incorporate multiple randomizations to efficiently test factorial experiments. Finally, I employ person-centered mixture models to measure and examine unobserved heterogeneity. Latent class analysis allows us to measure constructs that are categorical in nature but not directly observable. Examples of constructs I have modeled using LCA include alcohol control policies (for states as well as college campuses), substance use, alcohol enforcement practices by law enforcement agencies, food shopping, physical activity, and use of sexually explicit media. I also use mixture techniques longitudinally, including using them to cluster longitudinal trajectories (e.g., tobacco and alcohol use during adolescence and young adulthood) and to examine movements between latent classes over time (i.e., latent transition analysis) and correlates of these movements.

Teaching

Teaching Areas

As one of the methodologists in our Division, I helped develop the curriculum for methods training for our Epidemiology PhD program and serve as co-instructor for our core PhD analysis course (PubH 8342: Advanced Epidemiologic Methods: Applications). This course takes an in-depth look at regression (linear, logistic, Poisson, ordinal, multinomial), spline regression, covariance pattern modeling, multilevel modeling (random intercept, random slope), general estimating equations, survival analysis, principal component analysis, latent class analysis, confirmatory factor analysis, missing data estimation, and marginal effects estimation.
