Biographical details

Peter joined the Faculty in 2003 as a Principal Research Fellow in Functional Genomics and became Associate Professor of Genomics in 2008. He is responsible for the Faculty's Dog and Cat Genomics Research Initiative, and is presently developing the Canine Biobank Project, an integrated resource for canine genomics research.


He has over 25 years experience in research in the fields of genomics, immunology, immunogenetics, lymphocyte cell biology and lactation. He began his career in a research programme concerned with diabetes and transplantation immunology, before moving into the emerging field of molecular immunogenetics.

He completed a PhD at the University of Sydney working on canine MHC genes then went abroad as a post-doctoral fellow in the Division of Immunobiology at the University of Pennsylvania, Philadelphia. Upon returning to Australia he established a molecular immunobiology laboratory at the Westmead Millennium Institute where he continued studies of cytokine receptor biology, signal transduction and gene expression, and control of lymphocyte response. More recently he has developed projects that apply post-genomic technologies to understanding cellular systems.

His research work has been supported by the NIH (USA), Canine Research Foundation, National Health and Medical Research Council of Australia, NSW Cancer Council, Multiple Sclerosis Society of Australia, the Dairy CRC, Dairy Australia, and others.

Current projects

Canine Biobank Project - This kind of research has proven to be particularly powerful in dogs because of the breed structure and common ancestry. This study collects a large number of samples from Australian dogs to understand gene variation that exists in Australian dogs and the impact of the differences between dogs.
