Short Biography

I serve as Chief of the Fish Health Section at the U.S. Geological Survey, Western Fisheries Research Center in Seattle, Washington and head a team of scientists, technicians, post-doctoral researchers, graduate students and visiting scientists working to improve methods for the detection of fish pathogens, determine factors affecting the epidemiology of fish diseases, and develop novel control strategies for reducing losses among both hatchery-reared and wild fish. I am also an Affiliate Professor in the School of Aquatic and Fishery Sciences at the University of Washington where I serve on departmental or graduate student committees and teach the occasional lecture. I have served as: President of the Fish Health Section of the American Fisheries Society, member of the Editorial Boards of the Journal of Aquatic Animal Health, Diseases of Aquatic Organisms, Journal of Fish Diseases, and Journal of Applied Ichthyology, and member of the International Committee on Taxonomy of Viruses, the American Type Culture Collection, the USDA Aquaculture Technical and Scientific Committee, and the Fish Disease Commission of the World Organization for Animal Health. Significant awards include the Department of Interior Meritorious Service Award (1999), American Fisheries Society Fish Health Section S. F. Snieszko Distinguished Service Award (2000) and the Department of Interior Distinguished Service Award (2006). I am an author of more than 150 scientific publications.
