I am a veterinarian and professor of aquatic animal medicine at the North Carolina State University College of Veterinary Medicine (NCSU-CVM) where I have taught since 1993. I graduated from Gettysburg College in 1981 with a B.A. in biology, received an M.S. in biology with a concentration in marine biology from Northeastern University in 1985, and graduated from the University of Pennsylvania School of Veterinary Medicine in 1988. I worked for a large importer and wholesaler of tropical fishes for over 4 years before joining the faculty at the NCSU-CVM. I'm a diplomate of the American and European Colleges of Zoological Medicine and was named "2007 Exotic DVM of the Year" by the Zoological Medicine Network/Exotic DVM Magazine.

I'm an author on over 130 popular and scientific articles about invertebrates, fishes, amphibians and reptiles and speak nationally and internationally on these subjects. I have also authored or co-authored 20-plus book chapters on aquatic animal diseases and treatment and have edited or co-edited five veterinary books: Self Assessment Colour Review of Ornamental Fish (Manson Publishing and ISU Press, 1998; CRC Press, 2017); Invertebrate Medicine (Blackwell Publishing, 2006; 2012); Rapid Review of Exotic Animal Medicine and Husbandry (Manson Publishing, 2008).

I've written two novels, Ivory Hunters (1996) and Pavilion Key (2000), Krieger Publishing, Malabar, Florida. Both stories are scientific mysteries that raise important issues about wildlife conservation and man’s exploitation of the environment. I had the opportunity to explore southwestern Florida, where my novels are set, while living and working in Naples for several years. My wife Diane Deresienski (also a veterinarian) and I live in Raleigh with our mothers, two wonderful caregivers, three dogs, and a cat.
