As a program officer, Chris (2023-25 USDA fellow) cultivates and manages grants for innovative and applied conservation science and technology projects. In addition to developing new partnerships and strategic initiatives with the AAAS Fellowship Programs' environment portfolio, he leads development of the foundation's strategy for community-based conservation throughout Africa. "STPF showed me not only how science is conducted within federal agencies and how science informs and influences policy and practice; it also opened new doors for my career as a conservation scientist outside of academia and government," Chris shared.
