About Jan Freiwald

Jan Freiwald is the Director of Reef Check California a program of the Reef Check Foundation. Reef Check California trains volunteers as citizen scientists and works with them to monitor the rocky reef and kelp forest communities along the California coast. Reef Check California uses these innovative approaches to involve the public in marine resource management and at the same time to provide data to the state’s monitoring and management entities. As such Reef Check California is involved the MPA baseline monitoring and evaluation thought all regions of California. Jan Freiwald received his Ph.D. in marine ecology and evolutionary biology from the University of California Santa Cruz in 2009. He received a B.Sc. in marine biology from the same institution in 2002 after transferring there from the University Kiel, Germany where he studied biology. His dissertation focused on the effects of population density as well as biological habitat variables on the movement and home range size of temperate reef fishes. He has also worked on the genetics of temperate reef fishes and has many years of experience in subtidal monitoring and community ecology through his work with the Partnership for Interdisciplinary Study of Coastal Oceans (PISCO) and contract work with the U.S. Geological Service.
