This course allows PhD students to take part in a laboratory rotation system. During these rotations, students become familiar with research activity within departmental laboratories that are of interest to them. These rotations help students identify the laboratory in which they will perform their dissertation research. Postbachelor's PhD students must complete three rotations: one in their first semester of matriculation, and two in their second semester. Post-master's PhD students must complete a minimum of two rotations, one of which must be in their first semester of matriculation. Normally each rotation will last up to seven weeks.
