Tuition, Years 1-3: $26,770; Tuition, Years 4+: $3,700. PhD students who don't already have external fellowships are typically awarded full fellowship support at the time of admission, including tuition, fees, and stipend. This support is maintained through successful performance in the program and in the lab of the student's advisor. Some students also attain additional competitive fellowships (see below) as well as other external fellowships after they matriculate.
