Changrui Yuan

Changrui is a Computer Scientist on the Ecoinformatics and Wildlife Technology (ECOTECH) team at the U.S. Geological Survey's Fort Collins Science Center. ECOTECH is a multidisciplinary team of biologists, ecologists, statisticians, data scientists, and technologists dedicated to modernizing natural resource science. The team develops integrated scientific, hardware, and software solutions that bridge gaps between science, technology, people, and processes. Applying systems engineering principles, ECOTECH creates resilient, scalable platforms that support long-term biological monitoring programs and strengthen USGS's mission to deliver reliable, actionable science. Through close collaboration with diverse partners, the team designs adaptable tools, flexible data models, and cloud-based services that enhance efficiency, improve scientific outcomes, and maintain continuity of critical ecological information.

Changrui's primary project is Siren, the National Early Detection and Rapid Response (EDRR) Information System for invasive species. As the information hub of the National EDRR Framework, Siren serves as the online portal and collaboration center for a national interagency initiative to strengthen coordination and capacity across jurisdictional boundaries, enabling partners to efficiently detect and respond to new invasive species. Working closely with federal, state, local, academic, tribal, and territorial partners and end users, the Siren team delivers user-centered technical solutions to challenges in data management, information sharing, and the planning and prioritization of invasive species detection and response.

Changrui also works on SpeciesIncite, an AI-driven solution for compiling the current state of knowledge and best available science to inform and accelerate permitting decisions on federal lands. In addition, he contributes to the White-nose Syndrome (WNS) application, another ECOTECH project supporting bat conservation efforts.
