Dr Andrew Greenhill is a senior lecturer in microbiology at the School of Applied and Biomedical Sciences, Gippsland Campus.
Andrew's research addresses some of the most important infectious diseases in low-income countries, with a particular focus on bacterial infections. His major research foci over the past five years include investigations into the aetiology and diagnosis of enteric illnesses and acute respiratory infections; pneumococcal vaccines in a high-burden setting; and causes of intercurrent infections in HIV-positive people.
Andrew also has an interest in food microbiology, environmental microbiology, veterinary microbiology and environmental health. He is currently working on and developing cross-discipline research projects that encompass two or more of these fields on interest.
To date, much of Andrew's research has focused on infectious diseases in Papua New Guinea (PNG). The majority of Papua New Guinean's live in rural and remote areas of the country, where basic needs remain unmet. There is poor access to education, health care, and sanitation and hygiene; and there is generally low disposable income. These factors ensure infectious diseases remain the major health burden in PNG. The economy of PNG is undergoing rapid changes with the development of major resource based projects, which in turn should lead to increased national income. However, the direct impact of such projects on health can not be easily predicted. Dr Greenhill has played an important role in establishing surveillance and laboratory capacity to monitor the impact of one of the major resource projects in PNG.
Since 2009 Andrew has led studies investigating the incursion and spread of Vibrio cholerae into PNG. Despite poor access to improved water and sanitation in PNG, the country was previously non-endemic for cholera. Andrew and his collaborators continue to work on the molecular epidemiology of cholera and conduct ongoing surveilance and of environmental persistence of pathogenic V. cholerae. Andrew is also playing a leading role in various studies investigating the applicability of existing and potential future diagnostic tools for enteric diseases.
Andrew embraces cross-disciplinary research, using laboratory, clinical and social research tools to improve our understanding of important diseases in a low-income setting.
