The Institute supports residential student fellowships at the undergraduate through the postdoctoral level. Omidyar and Postdoctoral Fellows are in residence from one to three years working both on collaborative and individual projects. Generally there are openings for such scholars with a Fall application deadline. SFI supports a small number of graduate students in residence, all of whom are matriculating at other institutions. Usually such residencies are no more than one year and they are individually arranged. The Institute also hosts a small number of highly motivated and talented undergraduates as part of its NSF-supported Research Experiences for Undergraduates (REU) program. Application deadline for REU students is in early spring for student residencies during the summer term.
