Dr. Katherine Irving

Dr.rer.nat. Katherine Irving is a Scientist specializing in the relationship between the distribution of river species and their environment. Her doctoral degree dealt with the role of hydrology in Species’ Distribution Models (SDMs) on benthic macroinvertebrates. This work involved developing SDM methodology by creating a hydrologic dataset, optimizing variable selection and testing the performance of existing hydrological datasets. Her current research with SCCWRP focuses on the effects of hydrologic alteration through the development of flow-ecology models, aiming to conserve the health of Californian streams.

She received her doctoral degree from Berlin’s Liebniz Institute for Freshwater Ecology and Inland Fisheries and Freie Universistaet, her M.S. in freshwater and marine ecology from Queen Mary University of London, and her B.S. in marine biology from the University of Plymouth. She joined SCCWRP in 2019.
