The NMFS-Sea Grant Fellowships are available to students enrolled in or provisionally accepted to Ph.D. degree programs in academic institutions in the United States and its territories. The fellowship can provide support for up to three years for highly qualified graduate students working towards a Ph.D. in quantitative programs including ecology, ecosystem ecology, population dynamics or related fields of study such as wildlife biology, fishery biology, marine biology, quantitative ecology, applied mathematics, applied statistics, simulation modeling, marine resource economics, natural resource economics, or environmental economics. The NMFS-Sea Grant Fellowship Program in Population and Ecosystem Dynamics anticipates funding at least four new Ph.D. fellowships in 2024 to students who are interested in careers related to marine ecosystem and population dynamics. The emphasis will be on the research and development of quantitative methods for assessing the status of marine ecosystems; managed fish, invertebrates, and other targeted species; and marine mammals, seabirds, and other protected species. The NMFS-Sea Grant Fellowship Program in Marine Resource Economics anticipates funding at least one new Ph.D. fellowship in 2024 to students who are interested in careers related to the development and implementation of quantitative methods for assessing the economics of the conservation and management of living marine resources. A curriculum vitae and a minimum of two signed letters of recommendation are included in the required materials. The letters must be from the student's faculty advisor or the student's NMFS mentor. Please visit the fellowship's website for more information and the complete information about the required materials. Applicants may also contact the National Sea Grant College Program for questions.
