Leigh has a great depth of experience in anaesthetic and surgical research. He spent 14 years as Senior Scientist in the Departments of Anaesthesia and Pain Management (completing his PhD) and Cardiology at Royal North Shore Hospital. As tutor, then associate lecturer in veterinary anaesthesia at both the University of Queensland and the University of Sydney, he gained ACVSc membership.

Research has focussed on local anaesthesia but includes general anaesthesia and opioid analgetic synergy. Developing novel techniques including chaotic analyses, he builds research equipment and software for standardising algorithmic data analyses. He has researched adult stem-cells, cardio-thoracic surgery, cardiac device development and hyperperfusion.

A philosopher and ethicist, he served for a decade on New South Wales' largest ACEC and elsewhere in animal and human ethics. He consults in anaesthesia and cardiothoracic surgery for human surgical training and research.
