Overview

  • I received a DVM from the Cummings School of Veterinary Medicine at Tufts University in 2011, after which I completed a 3 years residency in Veterinary Anatomic Pathology at the Diagnostic Center for Population and Animal Health at Michigan State University, and one year of post-doctoral work in microbial pathogenesis.


    I joined the New Hampshire Veterinary Diagnostic Laboratory (NHVDL) and UNH in 2015.
    * My clinical work consists of diagnostic and investigational pathology serving primary care veterinarians, livestock producers, zoological collections, researchers, wildlife agencies, and rehabilitators.
    * My research is currently comprised of three main foci in the broader context of One Health: (1) emerging disease discovery, (2) wildlife diseases, and (3) comparative microbial genomics. These areas of research often have their basis in observations from diagnostic and research submissions to the NHVDL sections of pathology and microbiology. Active research in both areas relies on collaboration with multiple researchers and diagnosticians regionally and nationally.
