Profile

I completed my medical degree at the University of Melbourne in 1984, having also undertaken research for a Bachelor of Medical Science in 1981. I undertook a PhD in this department between 1986 and 1989, under Professor Trefor Morgan. I gained further experience in molecular biology at Harvard University (Victor Dzau’s lab) and then at the Centre for Genome Research at the University of Edinbugh, in John Mullins’s lab. I moved over to neuroscience research in 1992, when I joined Perry Bartlett’s lab (at WEHI) as an NH&MRC postdoctoral fellow. In 1995, I took up a senior lectureship in this department. I am also a vocationally registered general practitioner, and worked in this field part-time for 16 years.
I am an omnivorous reader, and also enjoy cycling, motorcycling, following football (North Melbourne) and cricket.

Research Profile, Interests and Recent Publications

My lab investigates the molecular mechanisms of neuronal death. In 1994, Perry Bartlett and I showed that the p75 neurotrophin receptor induces neuronal death. My lab is now particularly interested in p75's role in the death of cholinergic forebrain neurons during ageing and in Alzheimer's disease.
