Dr. Raphael D. Mazor is a freshwater biologist who specializes in freshwater bioassessment methods using benthic macroinvertebrates and algae. Working at large temporal and spatial scales, he has improved precision, accuracy, and sensitivity of bioassessments using the reference condition approach. In addition, he has studied the population genetics of rare and endangered invertebrates endemic to the vernal pools of California. His current research areas focus on the ecological impacts of hydrologic alteration, channel modification, and salinization. In addition, his research supports the development of tools to support the management of intermittent and ephemeral streams.

He received his B.A. in neuroscience and behavior from Columbia University in 1999 and Ph.D. in environmental science, policy, and management from the University of California, Berkeley in 2006. He joined SCCWRP in 2006.
