Dr. Katherine Irving
Dr. rer. nat. Katherine Irving is a Scientist specializing in understanding the relationship between river species and their environment. Her research primarily focuses on investigating the impacts of hydrologic alterations on the biota of Californian streams, while integrating various stressors known to significantly influence stream biotic condition, such as temperature variations and land use. Dr. Irving's work spans several key research themes at SCCWRP, including ecohydrology, bioassessment, and contaminants of emerging concern (CECs). Her approach involves applying advanced predictive modeling techniques to unravel the complexities of river ecosystems.
Dr. Irving earned her doctoral degree from Berlin's Leibniz Institute for Freshwater Ecology and Inland Fisheries and Freie Universität, where her research focused on the influence of hydrology in Species' Distribution Models (SDMs), particularly emphasizing benthic macroinvertebrates. She holds an M.S. in freshwater and marine ecology from Queen Mary University of London, and a B.S. in marine biology from the University of Plymouth. Dr. Irving joined SCCWRP in 2019.
