Dr. Lara Jansen

Scientist
Biology

Dr. Lara Jansen is a freshwater ecologist with expertise at the community level and at varying spatial scales. Her research centers on the drivers and dynamics of bioindicator communities such as algae and invertebrates in the context of specific management scenarios such as flow alterations. She has worked in a range of ecosystems from mountain lakes to subtropical wetlands and aims to elucidate the overlaps and deviations in biological responses across the multiple ecosystem types that lie within a watershed. Her work leverages field studies spanning environmental gradients and statistical modeling of key organisms and whole communities to further not only scientific understanding but also provide guidance for managing vulnerable aquatic ecosystems in varied landscapes.

She received a Ph.D. in aquatic ecology from Portland State University, a M.S in natural resource management from California State Polytechnic University, Humboldt and a B.S in environmental science from University of California, San Diego. She joined SCCWRP in 2025.
