The pair's winning project assessed the reproductive success of the Eastern mosquitofish, used as a surrogate to the Okaloosa darter. Results from this inquiry were important to the reintroduction of the formerly endangered species, the Okaloosa darter, into suitable stream systems to ensure population success. Chowdhury and Diaw's efforts in collaboration with the United States Fish and Wildlife Service, the Biology Department of Loyola University New Orleans, the Florida Fish and Wildlife Conservation Commission, and other students from the Young Women's Leadership School of East Harlem helped to reclassify the Etheostoma okaloosae from the status of endangered to threatened under the Endangered Species Act of 1973.
