Andrew Cohen


Andrew Cohen directs the Center for Research on Aquatic Bioinvasions in Richmond, California. His research has focused on assessing the extent and impacts of invasions, investigating how species characteristics and environmental factors affect the success of invasions, identifying the mechanisms that transport and release exotic species, and developing methods to manage that transport and release. His recent research focuses on ballast water regulation and treatment and the role of ballast water in spreading bacterial pathogens of humans and animals.

Dr. Cohen received his doctorate from the Energy and Resources Group at the University of California at Berkeley. He formerly served as the Executive Director of the Urban Creeks Council; as a Boardmember and Vice-President of the East Bay Municipal Utility District, one of California's largest water and wastewater agencies; and as the Director of the Biological Invasions program at the San Francisco Estuary Institute. He has served on the Executive Committee of the Western Regional Panel on Aquatic Nuisance Species; on the Advisory Board of the National Aquatic Nuisance Species Clearinghouse, on California's Technical Advisory Group on Ballast Water, as the Chair of California's Science Advisory Panel on the Response to the Qauagga/Zebra Mussel Invasion, and on the US EPA's Science Advisory Board Panel on Ballast Water. He was awarded a Pew Fellowship in Marine Conservation and the San Francisco BayKeeper's Environmental Achievement Award.

Dr. Cohen's general-interest publications include a natural history guide ('An Introduction to the San Francisco Estuary''), a history of coastal development ('Gateway to the Inland Coast''), and articles on the environment for Pacific Discovery and the Atlantic Monthly. His scientific and general-interest publications can be accessed at He also created the Exotics Guide, a website providing images and information on the non-native marine species on the North American Pacific Coast, at
