Jeanette leads TNC’s land science team in The Nature Conservancy’s California Chapter. The team focuses on developing and fostering a science enterprise to operate a climate-resilient, system of protected areas that maximizes retention of biodiversity and ecosystem services, produces replicable models of best practice in stewardship, fosters strategic relationships, engages the next generation of conservation stewards, and drives innovation at the forefront of conservation, restoration, and science.
Prior to taking on the role of director of science for the land program, Jeanette was director of science for TNC’s water program. Before joining The Nature Conservancy in 2006, Jeanette completed her Ph.D. in physical geography at the University of California, Berkeley, was a research scientist for the Confederated Tribes of the Umatilla Indian Reservation restoring freshwater mussels and Pacific lamprey to Tribal rivers and worked as a researcher at the National Geographic Magazine.
