What financial support can I expect?

All Ph.D. students admitted to SEAS or EPS are guaranteed tuition and stipend, i.e., a graduate fellowship, for the normal duration of their time at Harvard. During the first academic year the funding comes from Harvard, after that it comes from my research grants. I encourage my students once at Harvard to apply for external fellowships, because they look good on your CV and of course it brings some relief to my research grants. But that's not always feasible and I fully expect to be able to support you out of my grants in any case.
