Summary
👤
Senior🎓
Top SchoolDavid Ketchum is a research hydrologist and geospatial scientist with over a decade of experience translating remote sensing and hydrology science into practical water management for agriculture in the Western US. Based in Missoula, he combines academic rigor—a PhD from the University of Montana—with frontline public service at the Montana Department of Natural Resources & Conservation to inform policy and on-the-ground decisions. He has helped pioneer operational use of satellite-based evapotranspiration tools through multi-year collaboration with OpenET and recently secured nearly $500k in state funding to explore remote sensing in Montana’s water rights business. David publishes applied remote sensing assessments of agriculture and brings stakeholders together—from landowners to federal agencies—to implement science-based solutions. Known for bridging research and policy, he focuses on building decision-ready geospatial products rather than purely theoretical models.
