Research Interest

My primary research focus is antimicrobial stewardship in companion animal medicine, with a particular focus on behavioral practices. I am also interested in the kidneys and urinary tract, especially infections within these systems.

Teaching Interest

I enjoy being able to provide veterinary students and other veterinary practitioners tools to help with common issues encountered in practice, particularly around antimicrobial use and spectrum of care.

Clinical Interest

On the clinic floor I am most interested in renal and urinary cases, along with some interventional urinary procedures. I also enjoy management of complicated and multi-drug resistant bacterial infections.
