The Damon Runyon Cancer Research Foundation encourages all theoretical and experimental research relevant to the study of cancer and the search for cancer causes, mechanisms, therapies, and prevention. Candidates, already holding a Ph.D., must apply for the fellowship under the guidance of a sponsor—a scientist (tenured, tenure-track, or equivalent position) capable of providing mentorship to the fellow. 4-year fellowships are contingent upon satisfactory progress reports. A base stipend of $70,000 plus additional funding for expenses is provided.
