About me
I started my research career as Science and Engineering Research Council (now Science and Engineering Research Board)-funded Ph.D. scholar in the Biochemistry Department at the Queen’s Medical Centre at the University of Nottingham, UK, working on the purification of the D2-dopamine receptor from bovine brain. I then moved to Australia and found a position as a Research officer at the Department of Biochemistry at The University of Queensland working on acetaldehyde modification of proteins in alcohol abuse.
The role of protein modification in the toxicity of ethanol and other compounds such as clinical drugs, together with associated immune phenomena, has been my major research focus since that time. In 1992, I received a Postdoctoral Research fellowship from The University of Queensland to continue my work in the Department of Biochemistry. Later, in 1994 I received an NHMRC grant to continue my work on ethanol toxicity. In 1996 I was appointed as an Associate Lecturer in Biochemistry; in 1999 I was promoted to Lecturer, and in 2010 to Senior Lecturer. I was also appointed Director of Molecular Biology postgraduate Coursework programs in 2007. Part of my role as director of Postgraduate Coursework in Molecular Biology is to mentor students each semester in research projects in various laboratories throughout the university, including my own. I have also successfully graduated 10 honours students and 6 doctoral students.
Research focus and collaborations
Mechanisms of Drug-Induced Tissue Injury: liver, muscle, heart and brain injury have long been associated with the abuse and clinical use of drugs.
My predominant research interest focuses on ethanol, the most commonly abused drug in Western societies. Ethanol is widely tolerated but induces a wide variety of tissue injury in a small number of individuals. Thus, my main research focus is the investigation of immunological and genetic phenomena associated with this alcohol-induced tissue injury.
My main areas of research are focussed on providing the answers to the following questions:
- Does ethanol alter hepatic gene expression to cause liver damage?
- Is protein modification by ethanol metabolites involved in the aetiology of:
- alcoholic liver disease?
- alcoholic skeletal and cardiac myopathy?
- alcoholic brain injury?
Teaching interests
My teaching is split into three main areas:
- Teaching to health professions students: BIOC1011 – Molecular basis of life (Vet Sci); MEDI1011- Medical Science 1; PHYL1007 - Physiology for Human Movement Studies
- Teaching to science students: BIOL3006 - Biochemistry of Metabolism in Health & Disease
- Teaching to postgraduate coursework students: BIOC6001 - Introduction to Molecular Biology Laboratory

Researcher biography
Mechanisms of drug-induced liver damage.
Liver disease has long been associated with the abuse and clinical use of drugs. My research interests focus on ethanol, perhaps the most commonly abused drug, and the widely used non-steroidal anti-inflammatory drugs (NSAIDS). Both NSAIDS and ethanol are widely tolerated but induce liver disease in a small number of individuals.
Research projects listed below investigate immunological and genetic phenomena associated with drug-induced liver disease.
- Does ethanol alter hepatic gene expression to cause liver damage?
- Is protein modification by ethanol metabolites involved in the aetiology of alcoholic tissue injury?
- Are proteins modified by reactive molecules formed during ethanol metabolism viable biomarkers of ethanol intake?
