What financial support can I expect?

All Ph.D. students are guaranteed tuition and stipend for the normal duration of their time at Harvard. During the first academic year the funding comes from Harvard, and after that it comes either from my research grants or from external fellowships. You are encouraged to apply for these fellowships, not only for the funding benefits, but because they also look good on your CV. You also must work as a teaching assistant for two terms as part of your educational program, and this work will pay for part of your stipend.
