Funding Amounts: Salary and research support for up to 5 years; award budgets include salary, fringe benefits, and research-related expenses as determined by participating NIH Institutes/Centers.
Summary: Supports career development of clinicians committed to patient-oriented research, specifically for independent basic experimental studies with humans (K23 mechanism).
Key Information: Applicants must propose basic experimental studies with humans that meet both NIH clinical trial and basic research definitions; prior consultation with NIH staff and review of IC-specific requirements is strongly encouraged.
Description
This NIH opportunity provides mentored career development support for clinicians (with clinical doctoral degrees) who are committed to patient-oriented research, specifically for independent basic experimental studies involving humans. The K23 mechanism is designed to foster the transition of research-oriented clinicians to independent investigators by providing protected time (3–5 years) for research and career development activities. The focus is on studies that prospectively assign human participants to experimental conditions to understand fundamental aspects of phenomena, without specific application toward processes or products.
The program is open to a wide range of clinical disciplines and is intended to increase the pool of clinical researchers capable of translating biomedical discoveries into clinical settings. The proposed research must align with the scientific missions of one or more participating NIH Institutes or Centers.
