Three lab rotations are required during a PhD student's first year. One rotation must be experimental, one computational, and the third can be either option. Rotations typically last for a minimum of nine weeks and it is expected that the student will participate in the lab full time, except for time spent on classes and class work. Students report on each rotation by completing a Lab rotation Approval Form prior to the start of the rotation and a Lab Rotation Report Form at the end of the rotation.
