Associate Investigators

Professor Martyn Kirk 

Professor Martyn Kirk heads the Master of Philosophy in Applied Epidemiology at the Australian National University, which is the Australian Field Epidemiology Training Program (FETP). For over 25 years, he has worked at state, national and international levels at the interface of applied research and government policy. He has investigated numerous outbreaks due to respiratory, diarrhoeal and other agents, including across international boundaries. His research focuses on the causes of gastroenteritis and foodborne diseases in Australia and globally. Professor Kirk is a member of the Foodborne Disease Epidemiology Reference Group of the World Health Organization and he provides expert advice to governments on food- and waterborne disease and outbreak investigation.

Dr Christopher Degeling 

Dr Chris Degeling is a health social scientist, philosopher and veterinarian. He is a Senior Fellow at the Australian Centre for Health Engagement, Evidence and Values (ACHEEV) at the University of Wollongong and maintains an affiliation with the Marie Bashir Institute at the University of Sydney. His research focuses on the intersection of public health ethics, public health policy and emerging issues at the human-animal-ecosystem interface, as well as public and policy maker perceptions of infectious disease control measures (including acceptance of surveillance technologies) and outbreak response.

He has expertise in the development and application of microbial genotyping systems. More information about Dr O'Sullivan

Professor Dominic Dwyer

Professor Dominic Dwyer is Director of NSW Pathology West and Clinical Professor of Virology at the University of Sydney, with clinical and research expertise in diagnostics, pandemic influenza surveillance and management.  His influenza research includes assessing interventions to prevent influenza transmission in closed environments, and developing assays for seasonal and pandemic influenza. He serves on International, Commonwealth and State committees addressing policy and management of infections of public health significance. More information about Professor Dwyer

Associate Professor Cameron Webb

Associate Professor Cameron Webb is a Principal Hospital Scientist at Westmead Hospital and a Lecturer at the University of Sydney. He is an entomologist experienced in mosquito and mosquito-borne disease monitoring and management in coastal Australia, developing surveillance technologies for endemic and exotic mosquitoes and integrating mosquito management into urban planning and wetland design. He also has expertise on the impact that environmental changes will have on vector-borne diseases in Australia. Associate Professor Webb is also an enthusiastic proponent of public health communication. More information:
