Research Focus
  • Renin-angiotensin-aldosterone system - specifically the behavior of the enzymes, peptides, and receptors of this system during health and disease.
  • Heart Failure - specifically the medical management of congestive heart failure in dogs and cats and the impact of the renin-angiotensin-aldosterone system in the pathophysiology of this syndrome.
  • Heartworm disease - specifically the cardiac and pulmonary pathophysiology during infection and adulticide treatment.
  • Improving access to care in canine heartworm and myxomatous mitral valve disease.
  • Incorporating artificial intelligence to improve cardiovascular diagnostic test interpretation in general practice.
Specialty Focus
  • Clinical cardiovascular medicine
  • Cardiovascular physiology and pathophysiology
