I am a social epidemiologist and biostatistician with substantive research interests along several research streams including the prevention of homelessness, injury, and victimization. I am interested in evaluating strategies for preventing and resolving such problems at the individual, social, and community level. I have broad methodological interests and expertise in psychometrics, latent variable modeling, longitudinal data analysis, and randomized controlled trials.
