Dr. Dryden’s primary research focus has been the biology and control of fleas and ticks infesting dogs and cats. These research efforts have resulted in numerous publications on flea and tick ecology and control. These research efforts are possible by utilizing the collective strengths of a variety of team members including Research Technicians Vicki Smith, Deb Ritchie and Dr. Patricia Payne, Associate Professor of Veterinary Parasitology. The “Flea and Tick Team” has conducted in-home evaluations of these products in Manhattan KS and Tampa FL and field studies at the Konza Prairie Biologic Station.

A second area of research includes investigations into the epidemiology, diagnosis and control of gastrointestinal parasite in dogs and cats. Several studies have been completed including studies detailing the severity of parasite contamination of the environment, prevalence of parasite infestations in greyhounds in Kansas and development of anthelmintic resistance. A major focus of this research is evaluating fecal diagnostic techniques. Additionally, recent projects have included evaluating various diagnostic and treatment options for Giardiasis.

These research efforts have received both National and International recognition with over 120 published papers, 8 book chapters, and over 100 scientific presentations at national and international meetings. In 1995 he received the "Pfizer Award for Research Excellence" for contributions that significantly advance our knowledge of animal health, in 2005 he was awarded the Kansas Veterinary Medical Association’s “KSU-Distinguished Service Award”, in 2007 he received the Recognition Award in Urban Entomology from the North Central Branch of the Entomological Society of America, in 2010 he received the “Excellence in Teaching Award” from the American College of Veterinary Dermatology and in 2010 he was awarded the Veterinarian of the Year presented at the Purina® Pro Plan® 56th Annual Show Dogs of the Year® Awards at the Grand Hyatt in New York City.

Dr. Dryden has also appeared on television programs and media events in the U.S.( Good Morning America, CBS this Morning and the Discovery Channel), Canada, England, France, and Spain to explain the team’s research findings.



Dr. Dryden is the course coordinator of DMP 718 Veterinary Parasitology. In 2006 he received the Bayer Animal Health, Teaching Excellence Award in recognition of outstanding instruction of second year veterinary students.
