The National Institutes of Health (NIH) is offering a funding opportunity under the HEAL Initiative, aimed at understanding individual differences in human pain conditions through the R01 grant mechanism. This initiative seeks to support research that holistically examines inter-individual differences in pain experiences, focusing on personalized pain management strategies and the collection of clinical and preclinical data. The funding is particularly important for advancing knowledge on the biological and psychosocial factors influencing pain sensitivity and treatment responses, especially in underserved populations. NIH plans to allocate approximately $4 million for 3-4 awards, with each application eligible for up to $650,000 in direct costs over a five-year period. Interested applicants must submit their proposals by February 6, 2025, and can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
