Who We Are

The Pacific Shellfish Institute staff are experienced researchers with a wide variety of professional and academic backgrounds.



Bobbi Hudson, Research Biologist

Bobbi Hudson, Executive Director
As Executive Director, Bobbi manages research studies and general operations of the Institute. Bobbi joined PSI in 2006 as a Research Biologist, contributing to applied research projects on the interactions of shellfish culture with the natural environment, organic pollutants, and disease and environmental stress. Her leadership role began with a multi-faceted project evaluating the benefits and costs of shellfish in Washington State, and a survey-based study of the economic contributions of the West Coast shellfish industry. In June 2013 Bobbi transitioned to Executive Director, but continues to serve as a scientist for PSI's diverse portfolio of biological, oceanographic and social science research projects.

Bobbi Hudson holds a B.S. and a M.S. in Environmental Science from The Evergreen State College. Her primary research interests include valuation of ecosystem services, social and ecological carrying capacity, and intertidal ecology. Bobbi also specializes in evaluation of sustainable bivalve aquaculture production in near shore environments. Prior to joining PSI, Bobbi served as a fisheries technician with the U.S. Fish and Wildlife Service, and performed shellfish and finfish work aboard commercial vessels in Puget Sound and SE Alaska. Bobbi also spent three years as a public information officer for the state of Washington.

Dan Cheney, PhD, Senior Scientist

Dan Cheney, PhD, Senior Scientist
Dan Cheney specializes in aquaculture production systems, water quality analysis, environmental impact analysis and coastal resource management and inventories. Dan Cheney received a B.S. and Ph.D. in Fisheries from the University of Washington and a M.S. in Zoology from the University of Hawaii. Dan served as PSI's Executive Director from 1995 until late 2009, and remains on staff as a senior scientist. Dan is the principal investigator for several on-going federally and state funded applied research to examine the environmental interactions of shellfish production practices, develop methods to control Vibrio bacteria contamination and reduce the public health risk of raw shellfish, and assess heavy metal concentrations in west coast shellfish and determine human health risks.

Dan is also owner of BioAquatics International LLC (BAI) and supports this company's fisheries and aquaculture; coastal permitting; economic, environmental and biological assessment and natural resources practice. Dan's consulting work involves field and laboratory studies, including diving and video surveys, investigative reviews and analyses, and descriptive reporting for clients in Washington State, and elsewhere in the U.S. and Canada, and the Middle-East. Clients include private industry, public agencies, investment groups, and legal representatives.

Dr. Steve Booth, Senior Scientist

Steve Booth, PhD, Senior Scientist
Dr. Steve Booth specializes in integrated pest management. Steve received a Ph.D. in Entomology from Oregon State University, a M.S. in Biology from Western Washington University, and a B.S. in Zoology from the University of Iowa. Steve's Ph.D. program and a similar post-doctoral position in British Columbia involved the development and implementation of pest management programs that selectively targeted pests on pears, but allowed for the immigration and development of indigenous arthropod natural enemies. Prior to joining PSI, Steve worked for Washington State University, at the Vancouver Research Unit, examining the potential of microbial agents to suppress insect pests on small fruit. This work included the development of methods to isolate, formulate and produce entomopathogenic fungi.

Steve is currently involved in research to examine physical, chemical, and biological control options for burrowing shrimp on commercial oyster beds in southwest Washington State. This is a unique problem involving application of a pesticide against an indigenous pest in an estuary. Steve is also involved in similar research into potential impacts and control tactics for Japanese eelgrass (Z. japonica), which is listed as a class C noxious weed in Washington and is being actively eradicated in California. Steve is also the primary author on the recently released 'Illustrated Guide to Bivalve Pests in Washington and Oregon.'
