Dr. Carmen Messerlian, Assistant Professor of Environmental Reproductive, Perinatal, and Pediatric Epidemiology, remodeled the department’s gateway Reproductive and Perinatal Epidemiology I course after her first year teaching it. Drawing on key observations and 6-8 hours of one-on-one student meetings per week, “I wanted to understand students’ learning needs and requirements, their goals for the course, and where their training was going to take them.” From there, she synthesized both her own experience in the field and quantitative student review data to radically revise the course’s structure. Now the course helps students develop their scientific research skills, explicitly scaffolding how to perform activities that students rarely get formal training in, like academic journal peer reviews, abstract writing, and poster presentations. At its core, the course trains students “how to become a reproductive epidemiologist,” and to learn how to put on “an epidemiological lens” when they produce, digest, or evaluate material in the field.
