Rudolf von May, Ph.D.

Assistant Professor | Biology Program

California State University Channel Islands

Welcome! I am an Assistant Professor of Biology at CSU Channel Islands. I am broadly interested in ecology, evolution, and conservation of biodiversity. My research focuses on ecology and diversity of amphibians and reptiles, with a main emphasis in the Andes-Amazon region. I am especially interested in understanding the links between species’ distributions and their thermal ecology, morphology, and evolutionary history. Recent projects also focus on other organisms and ecosystems in California. Email: rudolf.vonmay at csuci.edu
