The American Association for the Advancement of Science (AAAS) is the largest general scientific society in the world. The Science & Technology Policy Fellowship (STPF) program offers hands-on opportunities to apply your scientific knowledge and technical skills to important societal challenges. After a yearlong assignment in the executive, legislative or judicial branch of the federal government in Washington, fellows become members of a large and influential network of policy-savvy leaders in government, academia, industry and nonprofits.
