Dr. Walsh has studied the immune systems of marine vertebrate species, including the cartilaginous fishes (sharks, skates, and rays), marine mammals, and sea turtles, for more than 20 years. Current projects include research on cytotoxic factors produced by cultured shark immune cells, antimicrobial properties of epidermal mucus from stingrays, effects of harmful algal blooms on human health as well as on the health of wildlife species including the Florida manatee and sea turtles. Dr. Walsh has also served as Quality Assurance Officer for Mote Marine Laboratory since 2000. Mote is certified through the Florida Department of Health Environmental Laboratory Certification Program for certain environmental testing parameters. Dr. Walsh is also a registered patent agent through the United States Patent and Trademark Office, and initiated Mote's patent program in 2002.
