Some fellowships will encourage you to identify funding sources for your second and third year. Ask about funding expectations during your fellowship interviews. If you anticipate applying for funding, discuss this with your fellowship director early on, as some deadlines fall even before you start fellowship. Fellows also may apply for grants for specific research studies, or begin applying for funding for the years after fellowship if that is in line with career plans. If you have interest in pursuing research as part of your carer, you should take advantage of any opportunities to read and write grants during your fellowship.
PIDS maintains a list of funding opportunities for investigators, fellows and issues some fellow awards of its own.
