I graduated in Medicine from the University of Birmingham, United Kingdom (UK), in 1984 and spent most of my junior hospital and academic training in Glasgow (PhD 1988). It was in Glasgow where I became Lecturer and Honourable Senior Registrar in Medicine and Therapeutics at the Western Infirmary with Professor John Reid, Regius Professor and Head.

I completed a 2-year British Heart Foundation Fellowship at Stanford University, California (USA), working with the world-famous Gerald Reaven M.D on mechanisms of insulin resistance in hypertension and cardiovascular disease. My laboratory research at Stanford was written into an M.D thesis (1994 Birmingham).

As Senior Lecturer in Clinical Pharmacology in the Department of Pharmacology, University of Sydney, I was working with Professor Paul Seale and Judy Black. My clinical work in Central Sydney Area Health service centred on 3 areas:

1. General Medicine at Concord Hospital with Professor Jim Lawrence and Michael Field.
2. Diabetes at Royal Prince Alfred Hospital alongside Professor Dennis Yue, John Turtle and Ian Caterson.
3. I worked in a joint medical obstetric clinic at RPAH and King George V Memorial Hospital managing women with pre-eclampsia (Professor John Horvath, Adrian Gillin, Annemarie Hennessey). Andrew Child and Brian Peat were the staff obstetricians. I was in Sydney from 1994-1997.

In 1997, I returned to the UK (aged 37) to take up the Professorship of Vascular Medicine in the University of Nottingham, based clinically in Derby. In 2003, I established Nottingham's 4-year graduate-entry medical course and held posts as Associate Dean and Head of School from 2007-13. After retiring from the University of Nottingham, in early 2020, I returned to Australia to undertake Locum work in Burnie, Tasmania. This was where COVID struck the hospital after returned travellers on a cruise ship caused cross-contamination.

Before retiring from practice, I held Locum posts in Burnie, Hervey Bay, Bundaberg, and the UK from 2020-2021. And, from 1998 until 2024, I was Editor-in-Chief of Diabetes Obesity and Metabolism; a journal focused on Pharmacology and Therapeutics with an impact factor of 6.49 in 2020.
