Dr Haynes’ research is focused on the discovery of methods to detect cardiovascular disease before it becomes clinically apparent (early-detection) and elucidating effective prevention strategies. He is the leading investigator on a number of projects related to cardiovascular health and disease in humans. He also supervises and mentors honours and PhD students in this research area. His experience and expertise relate to non-invasive in vivo imaging of cardiac (echocardiography), cerebral (transcranial Doppler) and peripheral blood vessel function (ultrasound) and their interaction with blood cells (phlebotomy, cell staining and flow cytometry). Using these methods he has published novel data related to the cellular mechanisms involved in the pathogenesis of atherosclerosis; highlighted mechanisms that explain the “exercise paradox”; been involved in the development of new methods to assess cerebrovascular function and microvascular structure; and novel exercise based methods to treat patients with chronic heart failure. He has collaborated with researchers and clinicians and carried out research projects at Fiona Stanley Hospital, Perth Cardiovascular Institute, Harry Perkins Institute of Medical Research and Royal Perth Hospital.

Current projects are focused on the developmental origins of adult disease (Barker Hypothesis) and health, including heart and artery function in the Raine Cohort. These projects are funded by the NHMRC and the National Heart Foundation of Australia. 

In 2022, he is unit coordinator of SSEH3301 Exercise Prescription and Nutrition for Health and Fitness; and has previously been involved in teaching Cardiac Rehabilitation to postgraduate (MSc) students working towards Accredited Exercise Physiologist status with the Australian governing body: Exercise and Sports Science Australia (ESSA).
