Stress and obesity can lead to high blood pressure and greatly increase the risk of life threatening cardiovascular events. This application seeks to determine which chemicals and parts of the brain are responsible for amplifying the responses to repeated stress and during obesity in animal models leading to hypertension.
Probing The Gene-Environment Interaction In Metabolic Disease

Summary
A major problem with modern medicine is it is based on the law of averages, assuming everybody responds in the same way to a drug or a diet. In view of the diversity between humans as a function of genetic, epigenetic and other factors this is not the case. In the clinic there is marked variation in the response to drugs commonly used to treat patients with type 2 diabetes. This proposal seeks to embrace this complexity to develop a precision medicine approach to future medical care.
Oxidative Processes In Vascular Health And Disease

Summary
The process that turns cut fruit brown when it is exposed to air is thought to cause disease of our blood vessels and heart as we age. Despite what we first thought, 'blocking' this oxidation process with antioxidant supplements does not lower heart disease. This is because oxidation not only causes harm but also is useful and essential for normal body function. Our research program aims to show which oxidative processes are needed for blood vessel health or cause vessel disease.
Pathophysiology And Treatment Of Malaria In Our Region

Summary
Malaria continues to kill 420,000 people/year. I will lead a team of clinical scientists in identifying how each of the different malaria parasites cause damage to small blood vessels, kidneys and other organs, and will test whether two different drugs can improve these processes and reduce illness. Many of my previous research findings have changed malaria treatment in Australia and across SE Asia, and, where appropriate, I will use new research findings to improve treatments.
Heart failure (HF) describes where the heart cannot pump adequately to meet the bodyÍs needs. Mortality remains high; therefore, there is an urgent need for new treatment approaches. The present grant aims to: (1) evaluate treatments for patients at high-risk for future development of HF (2) examine the ability to safely withdraw unnecessary HF drugs (3) focus on the effect of HF on the kidney via novel treatment strategies (4) examine the emerging role of cancer drugs in development of HF.
Improving Outcomes In Heart Failure Through Basic, Clinical And Translational Research

Summary
Heart failure (HF) is a common, chronic cardiovascular condition characterised by a reduced capacity of the heart to function. Patients with HF have a poor quality of life and significantly reduced survival. My proposed programme of research will improve the understanding of heart failure (HF) and lead to better treatments.
Sleep loss through sleep deprivation and sleep disorders is a common problem causing impaired brain and heart function as well as increasing human errors in the workplace. The fellowship will involve new research focusing on how better treatment of sleep problems can reduce blood pressure, vascular disease and road crashes. Cutting edge research facilities will help new studies into how jet lag and shiftwork impair health and how to counter this risk.
Personalised Exercise As Medicine. Optimising The Prescription To Maximise The Benefit

Summary
Humans have never been less physically active than in contemporary Western society. These studies will provide an evidence-basis to address the inactivity epidemic by laying the foundation for personalised and effective exercise prescriptions, to which people are more likely to adhere.
Sun Exposure, Vitamin D And Photohealth Over The Lifetime

Summary
Australia is a sunny country with a diverse population. Inappropriate sun exposure for skin type leads to skin cancer (mainly in the fair-skinned) and vitamin D deficiency (particularly in the darker-skinned). Potential benefits of sun exposure are broader than vitamin D production, but remain ill-defined. There are few data on appropriate sun exposure for children. This research fellowship builds the evidence to guide sun exposure messages.
In patients predisposed to metabolic diseases, excessive fats get delivered to various tissues. About 10 to 15% are converted into sphingolipids, many of which have deleterious effects on tissue function. Blocking sphingolipid production prevents diabetes and most cardiovascular diseases in rodents. We seek to better understand these mechanisms and determine how the observations can be translated into new therapies and better clinical outcomes.
