ADVANCING THE ANALYST COMMUNITY FOR THE BENEFIT OF PUBLIC HEALTH & THE ENVIRONMENT
Our board members are a unique group of highly skilled and passionate scientists and analysts, that are dedicated to ensuring the accuracy, transparency and proper implementation of environmental data and research. We believe that there is no greater threat to our planet than the climate crisis and the human impact on California ecosystems.
CSEA DIRECTOR & FOUNDER
Carolyn is a scientist and Director of the Clear Lake Environmental Research Center (CLERC). CLERC’s mission is to bring permanent science to the shores of Clear Lake in Lake County for scientific education and discovery, and solution to our water challenges.
She worked for Lake County Department of Water Resources for nine years looking after the health of Clear Lake, largest lake in California and oldest lake in the Americas. Carolyn now helps landowners realize their goals for environmental sustainability and in particular fire resilience after 68% Lake County has burned in the last four years. She established the only environmental laboratory in Lake County after realizing the need for such a service and familiarity with the academic laboratory environment. Carolyn was educated in England and the USA, obtaining BS Degrees in Biology and Manufacturing Engineering and MS Degrees in Technology of Crop Protection and Viticulture. Carolyn holds Pesticide Control Advisor and Qualified Applicator Licenses through the Department of Pesticide Regulation.
