Anna Brady-Estevez is an American chemical and environmental engineer and venture investor who became a prominent scientific voice in UAP media in 2026. A former program director at the National Science Foundation, she is a founding partner of American DeepTech, an investment firm that NewsNation has described as working to fund, develop and commercialize "UAP-derived and UAP-inspired technologies."

Brady-Estevez earned a bachelor's degree in chemical engineering and another in Spanish at Johns Hopkins University, where she captained the varsity cross-country and track teams. She completed a PhD in chemical and environmental engineering at Yale University as an NSF Graduate Research Fellow and served as president of the university's graduate and professional student government. Her doctoral work with environmental engineer Menachem Elimelech produced papers on carbon-nanotube filters for removing viruses and bacteria from water, including a 2008 study in the journal Small.

Her career has moved between industry, consulting and investment. Her Kauffman Fellows profile lists strategy posts at the power company AES and the engine maker Cummins, consulting at Boston Consulting Group and investment roles at Signal Lake and 4-Innovation. At NSF she managed part of the Small Business Innovation Research portfolio; agency award records name her as program officer on hundreds of SBIR and STTR grants that began between 2018 and late 2023, in fields ranging from fuel cells and battery materials to electric propulsion and blockchain tools. Conference biographies also list her as a former senior investment adviser in the Small Business Administration's SBIC program and as a co-host of NASA's Ecosystemic Futures podcast.

Brady-Estevez has spoken at events organized by the Disclosure Foundation, including a November 2025 program with the Yale UFO Society on UAP, innovation policy and national security. In April 2026 she appeared on Ross Coulthart's Reality Check on NewsNation to discuss UFOs, zero-point energy and NASA. In clips shared that spring she said she was "95% certain multiple nonhuman species are here interacting with us on Earth," said she had heard that such beings had given humanity advanced technology, and vouched for the credibility of Richard Banduric, a former aerospace engineer who says he worked on nonhuman technology. Commentators who shared the clips also reported her saying she had personally seen advanced craft. The All-domain Anomaly Resolution Office's 2024 historical report said it found no empirical evidence that the U.S. government or private industry had possessed extraterrestrial technology.

Brady-Estevez's significance lies in the credentials she brings to the argument that UAP research can yield usable technology. As a former federal science-funding official who directed early-stage grants and now runs an investment firm built partly around that premise, she has helped turn disclosure advocacy into a pitch about innovation, venture capital and national competitiveness.
