Graduated BSc (Hons) from Monash University in 1975, MSc from the University of Melbourne in 1979 and PhD from Monash University in 1984. In 1975 and 1976 I worked in the Infrared Astronomy group at Melbourne University. During 1984 and 1985 I undertook postdoctoral work in Astronomy at University College London. From 1986 I worked in the Defence Science & Technology Organisation where I enjoyed a multi-disciplinary career spanning electro-optical, infrared and radar technologies, operations research, systems engineering, complexity and network science and food science.

Since late-2002 I have undertaken research into variable stars as an avocation. My interests include M giants (SRs and Miras), eclipsing binaries and Symbiotic stars (SySt). I have experience in PEP and CCD photometry and have recently switched to using CMOS cameras for photometry. In particular I would like to help bring down the cost of photometry to get more citizen astronomers undertaking it.
