This course is the first of a three-course sequence (Cosmetic Science Capstone I, II and III; PCEU8180, 8185, and 8190) that requires comprehensive evaluation of a topic pertaining to cosmetic science or OTC drug development that demonstrates competency in multidisciplinary didactic coursework and scientific, regulatory, and business aspects of research and development related to personal care or topical drug products under direction of a faculty Mentor. The result is a Capstone Paper and an open oral presentation before the faculty Mentor, one of the Capstone co-coordinators, and at least one other faculty member. In Cosmetic Science Capstone I (PCEU8180) students will receive instruction and experience in researching a topic, including using online information sources, organizing acquired information and references including use of reference manager software, and using proper reference citation formats, and in technical writing and oral presentation skills, all through lectures and peer group exercises. In addition, there will be both lectures and individual consulting sessions with each student by course faculty to guide the student in selecting an appropriate Capstone topic and identification of an appropriate Faculty Mentor. The Mentor will then guide the student through primary development and research of the topic in Cosmetic Science Capstone II and completion of the Capstone paper and oral presentation in Cosmetic Capstone III. The Cosmetic Science Capstone co-coordinators will assist the Mentors as needed and provide oversight. Further, the peer groups established in this course for training exercises will be available for peer review and support through the total Cosmetic Science Capstone sequences of course.
