What is the NIH K08 grant?
The K08 is the NIH career development award for clinician-scientists (MDs, DOs, DDSs, etc.) doing laboratory or translational research. It provides 75% protected research time plus a research allowance for 3–5 years and is the standard training-to-independence path for physician-scientists planning to run a research lab.

Leveraging Health Systems to Optimize Regional Cancer Care Delivery
1K08CA300920-01A1Calista Harbaugh · UNIVERSITY OF MICHIGAN AT ANN ARBOR, MI · $293,430 · awarded Jun 3, 2026 · NIHPROJECT SUMMARY The dominant trend in healthcare is regional consolidation of hospitals into “hub-and-spoke” health systems. Integrated care across health systems should ensure that multidisciplinary cancer care is coordinated; yet, healthcare silos persist, perpetuating differences in care among individuals. I am a colorectal surgeon and trained health…
Cellular mechanisms of macrophage activation syndrome
5K08AI170918-02Susan Canny · UNIVERSITY OF WASHINGTON, WA · $187,692 · awarded Jun 2, 2026 · NIHABSTRACT Macrophage activation syndrome (MAS) or secondary hemophagocytic lymphohistiocytosis (sHLH) is a dysfunctional, potentially fatal, hyperinflammatory response that is characterized by abnormal activation of lymphocytes and phagocytes leading to an overproduction of inflammatory cytokines and damage of host tissues. In rheumatic disease, MAS most…
Role of Proteasome Overload in Pathogenesis of Retinitis Pigmentosa
5K08EY033857-05Oleg Alekseev · DUKE UNIVERSITY, NC · $170,704 · awarded Jun 1, 2026 · NIHPROJECT SUMMARY / ABSTRACT Retinitis pigmentosa (RP) is the most common hereditary cause of blindness, affecting over 1.5 million people worldwide. RP has an extraordinarily variable etiology, with over 5,000 distinct mutations in more than 300 genes implicated in its pathogenesis, which suggests that the most productive therapeutic interventions would…

Immune checkpoint inhibitors have revolutionized cancer treatment by leveraging our own immune system against tumor…
Dissecting mechanisms by which mRNA vaccines encoding nontumor antigens initiate antitumor immunity
1K08CA308866-01Adam Grippin · UNIVERSITY OF TX MD ANDERSON CAN CTR, TX · $136,270 · awarded Jun 1, 2026 · NIHImmune checkpoint inhibitors (ICIs) have significantly improved survival in many cancer patients, but most still fail to respond to these treatments. We and others have demonstrated that personalized mRNA lipid nanoparticle vaccines enhance antitumor immunity in combination with PD-1 inhibition. However, we recently found that mRNA vaccines targeting…
Rac1 and the actin cytoskeleton in renal tubular repair
5K08DK134879-04Fabian Bock · VANDERBILT UNIVERSITY MEDICAL CENTER, TN · $158,544 · awarded May 28, 2026 · NIHPolarized epithelial tubes are critical for an intact kidney. They control water, electrolyte, and nutrient homeostasis, all of which are deranged in chronic kidney disease. These specialized epithelia require a highly organized actin cytoskeleton that determines cellular shape and function. During renal epithelial repair, the actin cytoskeleton of…

Decision guide
Choose K08 when
Choose K08 when you are a clinician with a PhD or equivalent research training planning a lab-based career.
Choose another mechanism when
For patient-oriented or clinical-trials research, choose K23. For combined approaches, check institute FOAs — some allow either.
Who applies for K08
Clinicians within ~5 years of completion of subspecialty training, who want a primary research focus on basic or translational lab science. K08 is the lab-research counterpart to the patient-oriented K23.

K08 frequently asked questions
What is the difference between K08 and K23?
K08 supports clinicians doing primarily lab-based or translational research. K23 supports clinicians doing patient-oriented research (clinical trials, observational studies, behavioral interventions). Both are mentored 3–5 year career development awards.
How much salary support does the K08 provide?
K08 salary support varies by institute and your institutional salary cap, but covers up to 75% effort. Most institutes cap K08 salary support around $100K–$130K/year.
Can I apply for an R01 while still on K08?
Yes — applying for R01 in the last 1–2 years of K08 is standard practice and expected. The K08 is designed to bridge to R01 independence.
