This course introduces student to basic concepts and methods of epidemiology and population health. In this course, students learn how to measure disease incidence, prevalence, risk, relative risk and related concepts. Students also learn how to design, analyze and interpret studies that deploy methodologies ranging from case-control, cohort and randomized control trials (RCTs). Problems that plague such studies are explored including attrition, censoring, biased sampling, model misspecification, confounding or lurking variables. Finally, disease transmission dynamics are addressed along with network models that attempt to describe them.
