Dermatopathology Service

The University of Florida Veterinary Diagnostic Laboratories are pleased to offer a specialized dermatopathology service. The goal of our service is to provide high quality interpretation of animal skin biopsy specimens by pathologists with interest and expertise in dermatopathology. Our team includes 3 dermatopathologists with years of experience in this area.

In practice his special interests were dermatology, dentistry, complicated medicine cases, and surgery. He then completed a residency in anatomic pathology at the University of Florida in 2013, which was followed by a dermatopathology fellowship and position as a lecturer, all at the University of Florida, before being hired as a Clinical Assistant Professor. He is a Diplomate of the ACVP. His special interests include dermatopathology, diagnostic pathology, dermatology, immune-mediated disease, infectious disease, and allergy. He is the treasurer for the International Society of Veterinary Dermatopathology.

Our laboratories are interested in research projects involving disease process affecting the skin in animal species. Contact us if you are interested in a collaborative project and would like to submit research samples.

One of the main areas of focus of our lab is the investigation of skin microbiome of companion animals. Over the years, we have developed several studies describing the bacterial and fungal skin microbiome of dogs and cats. We have investigated the organisms colonizing healthy skin, as well as those with allergic conditions, and bad odor. We continue our interest in this field.
