Sarah Leupen received her Ph.D. in neurobiology from Northwestern University in 1998 and has taught a wide variety of biology courses at both small and large universities. She is currently a Senior Lecturer in Biological Sciences and an Honors College Fellow at the University of Maryland Baltimore County (UMBC) where she teaches physiology, anatomy, and neuroscience. She teaches with TBL in her undergraduate Anatomy and Physiology courses, where she has had great success in terms of both student learning and engagement. She has mentored and trained colleagues from Maryland to New Zealand in the use of TBL, and led workshops on TBL at teaching conferences, university departments, and for high school teachers. At UMBC, she founded and coordinates a campus-wide Team-Based Learning Interest Group, which has inspired colleagues in math, Spanish, and computer science to use TBL in their classrooms. Her particular interests in TBL focus on using the method with undergraduates, especially in the sciences and mathematics, and in medium to large classrooms (50-200 students).
