NIDCD Research Grants (R Series)

NIDCD R01 Research Project Grant

Funds investigator-led research on hearing, balance, taste, smell, voice, speech, and language through major grants.

The National Institute on Deafness and Other Communication Disorders (NIDCD), established in 1988 and operating within the National Institutes of Health under HHS, administers the R01 Research Project Grant as its primary investigator-initiated funding mechanism. NIDCD's mission is to conduct and support research on the normal and disordered processes of hearing, balance, taste, smell, voice, speech, and language, with a typical annual extramural budget near $540 million. R01 grants fund hypothesis-driven, multi-year biomedical research projects across all of these communication science domains.

NIDCD participates in three distinct R01 variants defined by clinical trial requirements: Clinical Trial Not Allowed, Clinical Trial Required, and Basic Experimental Studies with Humans Required. A fourth variant, the Stephen I. Katz Early Stage Investigator R01, specifically targets early-career researchers pursuing innovative directions without preliminary data. Eligible applicants include universities, medical and health professional schools, colleges, hospitals, research institutes, for-profit organizations, and government institutions registered in the United States. No individual investigators may apply directly; institutional affiliation is required. Award funds cover salaries, equipment, supplies, travel, and both direct and indirect research costs. New applications are due February 5, June 5, and October 5 each year, with renewals and resubmissions due March 5, July 5, and November 5.

Applicants should confirm topical fit with NIDCD program officers before submission, as the institute funds only research within its seven statutory mission areas. Priority areas in the current portfolio include auditory implant technologies, inner ear imaging, language development measurement, and the TALK (Tackling Acquisition of Language in Kids) initiative. Under the NIH-wide Trump 2.0 funding environment, several NIDCD NOFOs were reissued in 2025 with narrowed scope aligned to updated agency priorities, so researchers should read the current FOA carefully before preparing materials.
