The New Investigator Award Program (NIAP), launched by the National Alzheimer's Coordinating Center (NACC) in partnership with the Alzheimer's Association, is a prestigious funding opportunity designed to foster the career development of early-career investigators in the field of Alzheimer's Disease and Related Dementias (AD/ADRD) research. This program aims to encourage new and early career investigators to develop innovative research projects, foster collaborations within their Alzheimer's Disease Research Center (ADRC) and across the ADRC network and support their journey toward becoming independent researchers. A key component of the program is the NIAP Mentorship Program, a collaboration between NACC and the Research Education Component (REC) Steering Committee to support new and early-career investigators throughout the application process. Mentors are experienced researchers from the ADRC community who meet with applicants to provide one-on-one grantsmanship support to then during the application process, including reviewing specific aims and providing feedback on application drafts. The Mentorship Program consistently receives high ratings from both Mentors and applicants, the majority of whom report that the mentorship helped them prepare and submit stronger grant proposals.
