The goal of this FOA is to enhance the diversity of the drug abuse research workforce by providing dissertation awards on topics related to the study of basic and clinical neuroscience, development, epidemiology, prevention, treatment, services, or women and sex/gender differences as they relate to drug abuse. This support will enhance the pool of highly talented drug abuse scientists who conduct research within the funding priority areas. Applications are encouraged from doctoral candidates in a variety of academic disciplines and programs. This program will ultimately facilitate the entry of promising new investigators into the field of drug abuse research and promote transdisciplinary collaborations. This award is for up to two years of support for the completion of the doctoral dissertation research project.
