This initiative aims to support small, well-defined research projects focused on the etiology, epidemiology, diagnosis, and service delivery related to ASD, with grants designed to be completed within two years and requiring limited resources. The total funding available is capped at $100,000 over two years, with a maximum of $50,000 per year, and applications will be evaluated based on significance, innovation, and approach, among other criteria. Interested applicants must submit their proposals by November 16, 2024, and can reach out to the NIH OER Webmaster at FBOWebmaster@OD.NIH.GOV for assistance with the application process.
