After completing a PhD in virology Mark undertook a NHMRC CJ Martin Postdoctoral Fellowship on hepatitis C virus (HCV) at the prestigious MRC Virology Unit in the UK, working with Dr John McLauchlan. He now heads the Viral Hepatitis Pathogenesis group at Storr Liver Unit, The Westmead Institute for Medical Research, with a broad range of projects ranging from basic molecular pathogenesis to clinical research.

Mark runs a hepatitis clinic at Blacktown Hospital, treating patients with chronic hepatitis B and hepatitis C, and also sees patients at Westmead Hospital with a range of infectious diseases.




Professor Dominic Dwyer
Clinical virology and pandemic preparedness

Prof Dominic Dwyer

Professor Dominic Dwyer is a medical virologist and infectious diseases physician in the Centre for Infectious Diseases and Microbiology Laboratory Services, located in the ICPMR at Westmead Hospital, Sydney. Dominic has a clinical and research interest in viral diseases of public health importance. This includes HIV (where he coordinates an active program in antiretroviral drug resistance and HIV molecular epidemiology in Australia and the region), influenza and other respiratory viruses, and arboviruses. He leads an antiviral trials unit that has participated in over sixty studies of antiviral drugs and vaccines.

Dominic's influenza research includes assessing interventions to prevent influenza transmission in closed environments, and developing assays for seasonal and pandemic influenza. CIDMLS has enhanced the laboratory investigative capacity in NSW for infectious disease outbreaks, with his particular focus being rapid detection and molecular epidemiology of outbreak and emerging viruses.



Professor Lyn Gilbert
Infection control, vaccine preventable diseases and bioethics

Prof Lyn Gilbert

Professor Lyn Gilbert is an infectious diseases physician and clinical microbiologist who was director of laboratory services at the Centre for Infectious Diseases and Microbiology (CIDM), ICPMR, from 1991 to 2010. Lyn is a clinical professor at the University of Sydney, senior researcher in the Marie Bashir Institute and research associate at the Centre for Values, Ethics and the Law in Medicine (VELiM). Her research has previously focused on microbial epidemiology, prevention and control of many types of communicable diseases including healthcare-associated infections.

Lyn has recently commenced a PhD on ethics and politics of hospital infection prevention and control.





Professor Jon Iredell
Critical infections and mechanisms of antibiotic resistance

Prof Jon Iredell

Professor Iredell started at Westmead nearly 15 years ago on the general roster as a staff intensivist as well as in infectious diseases and microbiology, but practises now only in the latter two disciplines.

Jon's research interests are at the nexus of these disciplines and in bacterial genetics, and his session today examines the scientific basis of antibiotic stewardship and microbial husbandry.







Professor Wieland Meyer
Epidemiology of pathogenic fungi

Prof Wieland Meyer

Professor Wieland Meyer is head of the Molecular Mycology Research Laboratory at the Centre for Infectious Diseases and Microbiology. Wieland graduated in genetics with a Diploma in Biology (MSc, suma cum laude), from the Humboldt University of Berlin, Germany and went on to complete his PhD (suma cum laude), at the same University in 1992. He undertook his postdoctoral studies at the Department of Microbiology at Duke University Medical Center, Durham, NC, USA, before he established the Molecular Mycology Laboratory at Westmead and the Australian National Molecular Mycology Reference Laboratory. Wieland was the vice-president (1998-2002) and president (2002-2005) of the Australasian Mycological Society. He is the Convenor of the Mycology Special Interest Group of the Australian Society for Microbiology (since 2002) and the vice-president of the International Mycological Association (IMA) since 2006.

Wieland has written extensively (more than 90 papers and three books) on molecular epidemiology, population genetics, phylogeny, virulence and molecular identification of pathogenic fungi (including: Aspergillus and Scedosporium), especially yeasts of the genera Candida and Cryptococcus.   


Dr Matthew O'Sullivan
Infection control, antibiotic resistance and stewardship

Dr Matthew O

Dr Matthew O’Sullivan is an infectious diseases physician and clinical microbiologist in the Centre for Infectious Diseases and Microbiology, Westmead Hospital. Matthew also has an appointment as a senior lecturer with the Sydney Medical School, University of Sydney.

His research interests include the utilisation of microbial subtyping in the surveillance and control of hospital acquired infections, and the molecular epidemiology of methicillin-resistant Staphylococcus aureus.







A/Professor Vitali Sintchenko
Public health microbiology, surveillance and informatics

A/Prof Vitali Sintchenko

A/Professor Vitali Sintchenko, director of Centre for Infectious Diseases and Microbiology – Public Health  (CIDM-PH) is an academic pathologist/clinical microbiologist with a long-standing interest in the public health microbiology, biosurveillance, molecular diagnostics and epidemiology of pathogens with epidemic potential as well as infectious disease informatics.

Vitali is an associate professor, Sydney Medical School, The University of Sydney; supervising pathologist, NSW Mycobacterium Reference Laboratory, Centre for Infectious Diseases and Microbiology Laboratory Services, Pathology West, Westmead Hospital; a research associate of the Marie Bashir Institute for Infectious Diseases and Biosecurity University of Sydney; visiting senior research fellow, Centre for Health Informatics, University of New South Wales and chair of the Public Health Laboratory Network of Australia.




Professor Tania Sorrell
Emerging infectious diseases and fungal infections


Professor Tania Sorrell is the director of the Marie Bashir Institute for Infectious Diseases and Biosecurity (MBI) and the Centre for Infectious Diseases and Microbiology Westmead; Professor of Clinical Infectious Diseases and a senior physician in infectious diseases at Westmead Hospital, Sydney.

Tania has long-standing interests in prevention, diagnosis and treatment of infectious diseases, especially in immunocompromised hosts, and in the emergence of resistant micro-organisms.

Her research into the serious fungal infection, cryptococcosis, has provided new insights into host-microbial interactions and new drug development.

Tania has developed new diagnostics for fungal diseases and is on international committees developing guidelines for therapy.

She has served/serves on state and national advisory committees in infectious diseases, including pandemic planning for influenza, approval of therapeutic agents and both the research and human ethics committees of the National Health and Medical Research Council of Australia.


Dr Cameron Webb
Medical entomology and vectors of infectious diseases

Dr Cameron Webb

Dr Cameron Webb is a clinical lecturer with the University of Sydney and principal hospital scientist with the Department of Medical Entomology at Pathology West - ICPMR Westmead (Westmead Hospital). Cameron's primary focus is understanding the role of environmental management and urban development in reducing the risks of mosquito-borne disease caused by Murray Valley encephalitis virus, Ross River virus and Barmah Forest virus. However, he has also been called on to provide expert advice on a range of medically important arthropods, such as ticks, mites, biting midges, bed bugs and flies, to local, state and federal government agencies.

Key to Cameron's research is an understanding of the ecological role of mosquitoes and how wetland conservation, construction and rehabilitation projects may influence regional mosquito-borne disease risk together with changes in the local environment resulting from climate change, potential introductions of exotic mosquito species and personal protection strategies (e.g. insect repellents).

In his position with the University of Sydney, Cameron regularly provides lectures in a range of undergraduate and post graduate courses and has supervised a number of research students including collaborative projects with the University of Western Sydney, the Australian Catholic University and the University of South Australia.
