Susan completed her BSc (Hons1) degree at the Australian National University, ACT, Australia in 1978 and graduated in 1982 with a PhD in Biochemistry, University of Adelaide, South Australia, mapping and sequencing human histone genes, under the supervision of Dr Julian Wells.

Susan spent her postdoctoral years at Biotechnology Australia from 1983-1988 leading studies on recombinant vaccine development and eukaryotic expression of human inhibin, Il-3 and GMCSF. In 1992, she returned to basic research as Group Leader of the Gene Regulation Unit at the Kanematsu Laboratories, Royal Prince Alfred Hospital where she developed and implemented bisulphite sequencing for DNA methylation analysis.  In 2000, she established and headed the Epigenetics Group at the Sydney Cancer Centre, Royal Prince Alfred Hospital and in 2004 moved her group to the Garvan Institute of Medical Research and initiated and led the growth of the Epigenetics Research Program in the Cancer Research Division.  

Her DNA methylation studies over the last twenty years have initiated profound questions about the importance of epigenetics in early development and in disease, especially in cancer.  Susan has made extensive ground-breaking discoveries relating to DNA methylation patterns in normal and cancer genomes, that have led to the commercialization of new methylation-based tests for early cancer detection.  The techniques she pioneered in the early 1990s, including bisulphite sequencing, have revolutionised and now underpin the new era in epigen"omic" research. She was founding member of IHEC (International Human Epigenome Consortium) and led the formation of the AEpiA (Australian Epigenetics Alliance). 

She has a number of awards including the RPAH Research Medal in 2002, Julian Wells Medal in 2003, “Biochemisch Analytik Preis” for outstanding contribution for Methylation analysis in 2004.  In 2006 was elected a Fellow of the World Technology Network for Biotechnology, in 2009 was awarded one of Australia’s "Top Ten" National Health and Medical Research (NHMRC) Project Scientists and the Rotary Award for Vocational Excellence in 2012.
