Students are required to perform three distinct four-week laboratory rotations in the summer term of the first year. These rotations provide students with an opportunity to perform experimental research in three different scientific areas, while experiencing diverse laboratory environments and practices. They also facilitate selection of the dissertation laboratory and advisor. Students select the laboratory rotations based on their research interests and in consultation with their academic advisor. To capitalize on the cross campus nature of the program, students are required to distribute the rotations between participating laboratories in the Department of Biological Sciences and the School of Medicine.
