General Research Interests

Cancers occurring in pet animals are common and share morphology, biologic behavior and many molecular features with human cancers. Therefore cancers in pet animals provide a potentially useful means to understand cancers in all species. My roles as a both veterinary clinician and scientist facilitate the combination of molecular and cellular biologic techniques with veterinary clinical investigations. The overarching goals of this research are 1) to improve the ability to prevent, detect, and treat cancer and 2) to develop new animal models for translational cancer research. 

Selected Research Projects

  • Effects of anti-angiogenic therapy in feline oral squamous cell carcinoma.
  • Investigating canine hereditary Gastric carcinoma susceptibility.
