Dr. Raphael Mazor
Raphael D. Mazor is a freshwater biologist specializing in bioassessment using benthic macroinvertebrates, periphyton, and other aquatic organisms. 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. Dr. Mazor joined SCCWRP in 2006. His research focuses on the development and evaluation of regional bioassessment programs for Mediterranean-climate streams in southern California.

Areas of Expertise
Dr. Mazor specializes in developing and evaluating bioassessment programs in rivers, streams, and wetlands 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, particularly in intermittent and ephemeral streams.
