VME 6771 Research Methods in Epidemiology


Course schedule Power point handouts and reading materials Epi Tools VEM 5503 Veterinary Epidemiology

This is a 3-credit graduate course offered annually in the Summer semester. The course is structured in two parts. Part I is an introduction to basic principles and methods in epidemiology. Part II are series of lectures on experimental and observational study designs, journal club sessions, and computer lab sessions where students analyze research data from published epidemiologic studies. At the end of this course, students are trained to properly design clinical or population studies to test research hypotheses that justify the use of one or more study designs such as clinical trials, cohort studies, case-control studies, or cross-sectional studies. As part of this course, students are required to prepare and present three research protocols that may or may not be related to his/her graduate studies.
