Michael Kramer, Ph.D., Assistant Professor of Epidemiology. The Rollins School of Public
Health at Emory University, where he teaches maternal and child health epidemiology and
methods in social epidemiology. His research interests are largely centered at the intersection
of perinatal and early childhood outcomes, social determinants of health, and spatial analysis,

neighborhood deprivation and early academic readiness.
Directed acyclic graphs (DAGs) are hypothesized causal diagrams that can be used to assess sources of bias in epidemiologic studies based on a set of rules for interpretation. Increasingly, DAGs have been recognized as a valuable tool for evaluating confounding, but they have other uses as well such as clearly communicating underlying assumptions. This webinar is intended to provide a general introduction to DAGs using maternal and child health examples.
Penelope (Penny) Howards, PhD, Department of Epidemiology, Rollins School of Public Health, Emory University. Dr. Howards is a reproductive epidemiologist with an interest in methodological issues. Recently, she has been exploring how directed acyclic graphs (DAGs) affect our understanding of confounding specifically in relation to statistical adjustment for reproductive history.
Todd D. Little, Ph.D., Professor, Director Quantitative Program, Director Center for Research Methods and Data Analysis, Director University of Kansas Summer Stats Camps at the Department of Psychology at the University of Kansas, where he provides graduate-level training in an array of multivariate statistical techniques including structural equation modeling and growth curve modeling. The majority of his research focuses on using a unifying theoretical perspective. Dr. Little studies developmental changes in how children's and adolescents' action-control processes (i.e., motivational and self-regulation) influence (a) their adjustment and achievement in school settings, (b) their peer and friendship relationships, (c) their reasons for aggression and victimization, and (d) their ability to cope with challenging and stressful events.
Conditioning on intermediates between an exposure and outcome of interest can give rise to paradoxical associations if control is not made for intermediate-outcome confounding.
If control for both exposure-outcome and mediator-outcome confounding is made it is possible to decompose the overall effect of an exposure into a direct effect and a mediated effect.
Sensitivity analysis can be used to assess the impact of violations in confounding assumptions.
Tyler VanderWeele, Ph.D., Associate Professor, Departments of Epidemiology and Biostatistics at Harvard School of Public Health, where he teaches graduate-level courses on study design in epidemiologic research. The majority of his research focuses on causal inference, epidemiologic methods, mediation analysis, spillover effects, interaction, confounding, sensitivity analysis, measurement error, and causal diagrams with more than 134 articles in peer-reviewed journals.
