I am a co-instructor for both the Clinical Veterinary Parasitology course for 2nd year veterinary students as well as the parasitology portion of 4th year clinical rotations.


Our laboratory focuses on two major groups of parasites and diseases. 1) Ticks and tick-borne diseases; 2) Fleas and flea-borne diseases.

Ticks and tick-borne diseases

Our current projects on ticks include surveillance of ticks and tick-borne diseases of horses. The overall goal is to document the burden of ticks on horses and the medical risk they pose to help advocate for better, longer-lasting tick control for horses.

In general, our lab is interested in many, very broad aspects around ticks and tick-borne diseases including the epidemiology of Lyme borreliosis in humans and dogs in North America, evaluation of diagnostic assays for tick-borne diseases, and evaluation of acaricidal efficacy against ticks.

Fleas and flea-borne diseases

Our current projects on ticks include the evaluation of insecticidal products as a means to control home infestations with fleas and the management of flea allergy dermatitis. This is the continuation of work that has been carried out at Kansas State University for the majority of the last 3 decades.

Our lab also maintains a multi-drug resistant strain of fleas, which are used in the development and testing of novel insecticide products. Overall, our lab is interested in helping to find and develop the next generation of insecticidal products and to evaluate their ability to manage flea infestations, home infestations, flea allergy dermatitis, and flea-borne diseases.

Although our research focus is on ticks and fleas, Dr. Herrin enjoys working with all parasites of veterinary importance through the diagnostic service and teaching/outreach opportunities.
