This course is focused on epidemiologic methods, with an emphasis on the design and conduct of quantitative studies. The learning outcomes of this course are to extend students' appreciation of the scope-of-content of the epidemiologic toolbox and to deepen their understanding of the methodological challenges in the design of epidemiologic studies for answering a research question, and the practical aspects of carrying out such a study. Inevitably, as we work through two detailed protocols per student, we will dive into the details of several different methodological challenges and thus provide exposure and learning on various epidemiological concepts.
