Introduction
Catherine Hankins (born 12 March 1958) is an American environmental scientist renowned for her pioneering research on climate change impacts and ecosystem resilience. Over a career spanning more than four decades, she has held faculty positions at several leading universities, directed large interdisciplinary research projects, and served in advisory roles to governments and international organizations. Her work has contributed to the development of climate adaptation strategies used by municipalities worldwide and has influenced policy frameworks addressing biodiversity loss and sustainable development.
Early Life and Education
Childhood and Family Background
Catherine Hankins was born in Seattle, Washington, to Eleanor and Harold Hankins. Her father, a civil engineer, and her mother, a schoolteacher, fostered an environment that valued scientific inquiry and community service. Growing up in the Pacific Northwest, she spent many afternoons exploring wetlands and observing local wildlife, experiences that sparked an early fascination with ecological systems.
Secondary Education
She attended the University of Washington High School, where she excelled in biology, chemistry, and mathematics. During her senior year, she completed a senior science project on the effects of nutrient runoff on coastal algae, earning a scholarship to study environmental science at the University of Washington. Her undergraduate thesis, supervised by Professor Margaret Ellis, examined the dynamics of riparian buffer zones in urban streams.
Graduate Studies
After earning a Bachelor of Science in Environmental Science in 1980, Hankins pursued a Master’s degree in Ecology at Stanford University, completing her thesis in 1982 on the role of keystone species in temperate forest regeneration. She continued at Stanford for her Ph.D. in 1986, focusing on the interactions between atmospheric chemistry and terrestrial carbon sequestration. Her dissertation, titled "Quantitative Modeling of Carbon Fluxes in Mixed Forest Ecosystems," was later published as a foundational text in forest ecology.
Academic and Professional Career
Early Research Positions
Following her doctoral work, Hankins joined the United States Geological Survey (USGS) as a postdoctoral researcher, where she investigated the long-term effects of drought on watershed productivity. Her contributions during this period led to the establishment of a national dataset that tracks forest health metrics across the continental United States.
University Faculty Positions
In 1990, she accepted a faculty appointment at the University of California, Davis, as an Assistant Professor in the Department of Environmental Sciences. She was promoted to Associate Professor in 1996 and to full Professor in 2003. At UC Davis, she established the Climate Resilience Laboratory, a research center that integrates remote sensing, field ecology, and climate modeling to assess ecosystem responses to climatic stressors.
Leadership and Interdisciplinary Collaboration
Hankins has chaired several interdisciplinary research consortia, most notably the National Consortium for Climate Impact Assessment, which brought together climatologists, ecologists, economists, and sociologists to produce comprehensive vulnerability assessments for coastal communities. She has also served as the principal investigator for the Pacific Northwest Climate Adaptation Initiative, a federally funded program that evaluates adaptive capacity across multiple sectors.
Key Scientific Contributions
Climate Modeling and Ecosystem Dynamics
One of Hankins’ most significant contributions lies in the development of coupled climate-ecosystem models that predict how changes in temperature, precipitation, and atmospheric CO₂ concentrations influence plant growth, soil respiration, and water cycling. Her 2001 paper, "Integrating Terrestrial Carbon Budgets into Regional Climate Models," was widely cited and has been incorporated into subsequent iterations of the Coupled Model Intercomparison Project.
Ecosystem Services Valuation
In the early 2000s, Hankins pioneered methods for quantifying ecosystem services - such as carbon sequestration, water purification, and pollination - in economic terms. Her research demonstrated that investments in forest restoration yield returns that far exceed their initial costs, influencing land‑use policies in both the United States and Canada.
Policy Impact and Climate Adaptation Frameworks
Beyond theoretical work, Hankins has translated scientific findings into actionable policy recommendations. Her role as lead author on the National Climate Adaptation Strategy, published in 2010, provided a framework that municipalities have adopted to guide infrastructure planning, disaster preparedness, and natural resource management.
Interdisciplinary Methodology Development
Hankins is also noted for her efforts to bridge quantitative and qualitative research. She developed the "Mixed‑Methods Ecological Assessment" (MMEA) approach, which combines remote sensing data with community-based participatory research to produce holistic vulnerability assessments that consider ecological, economic, and social dimensions.
Awards and Honors
Over her career, Hankins has received numerous recognitions. In 1998 she was awarded the National Science Foundation Early Career Award for Outstanding Research in Environmental Sciences. She was elected a Fellow of the American Association for the Advancement of Science (AAAS) in 2005, and in 2015 received the International Conservation Award from the World Wildlife Fund for her contributions to forest conservation and climate policy. In 2020, she was honored with the National Medal of Science, the highest scientific award in the United States.

Book Chapters and Edited Volumes
Hankins has authored several book chapters, including contributions to "Climate Change and Ecosystem Resilience" (Springer, 2006) and "Urban Ecology and Planning" (Cambridge University Press, 2013). She edited the volume "Applied Ecological Modeling" (Princeton University Press, 2015), which collects case studies on model applications in environmental management.
Patents
Her research led to the development of a sensor network for monitoring soil moisture and temperature in real time. In 2012, she was granted U.S. Patent No. 8,123,456 for the "Integrated Soil–Climate Monitoring System," which is used in several agricultural research projects.
Personal Life and Legacy
Catherine Hankins married Dr. Thomas Lee, a geophysicist, in 1985. The couple has two children, both of whom pursued careers in the natural sciences. Outside of academia, she has served on the board of the Friends of the Pacific Northwest Wilderness and is an active volunteer with the Sierra Club. Her dedication to mentoring has resulted in the establishment of the Hankins Fellowship, an award that supports early‑career scientists working on climate resilience.
Hankins’ legacy is evident in the widespread adoption of her modeling frameworks and policy recommendations. Her interdisciplinary approach has become a standard in environmental science curricula, and her emphasis on translating research into practical solutions continues to influence both government agencies and non‑profit organizations worldwide. The integration of ecosystem service valuation into policy design, a concept she championed, has reshaped how natural resources are accounted for in national budgets.
