Research Interests

The focus of our research is new treatments for heart disease. We apply circadian (diurnal) physiological and pharmacological approaches to discover new treatments for heart attacks (myocardial infarction); high blood pressure (hypertension) and cardiac hypertrophy; and heart failure. We have state-of-the-art cardiovascular facilities and use leading edge transgenic, physiologic, molecular and preclinical approaches to benefit the treatment of heart disease.

We are recruiting MSc and PhD and Postdoc students for Cardiovascular Research projects  – see link for more information:
