Andrea graduated with a PhD in microbiology from the University of Sydney in 2014, joining the Koala Health Hub later that year. She oversees the operational aspects of the KHH’s diagnostic services, including the real-time PCR tests for Chlamydia and maintaining our koala DNA database. Andrea is also involved in client-based consultancy work and offers technical advice, support and supervision to undergraduate and post-graduate students undergoing training in koala health research in the Hub.


David is Associate Professor in Exotic Animal Medicine and Surgery and Wildlife Health and Conservation. He joined the University of Sydney as the Director of the Wildlife Health and Conservation Centre and the Avian Reptile and Exotic Pet Hospital in 2006 and has taught exotic pet and wildlife medicine and husbandry, and conservation biology since 1993. He is coordinator for the Masters of Wildlife Health and Population Management program.  David’s research interests include diseases of wildlife and exotic animals, as well as wildlife ecology and conservation. His current koala research involves habitat use, genetic diversity and the impact of disease on low density koala populations in the lower Blue Mountains, Campbelltown, and the Wollondilly and Wingecarribee Shires and also far southeastern New South Wales.


Mark Krockenberger is Associate Professor of Veterinary Pathology at the University of Sydney who has been working with koalas for the past 20 years. He is a Fellow of the Australian and New Zealand College of Veterinary Scientists in Veterinary Anatomical Pathology and a registered specialist veterinary pathologist and he is Associate Head of Clinical Services in the Sydney School of Veterinary Science. Mark is an active researcher in koala diseases, particularly cryptococcosis, and assists many groups and vets managing this disease in captive or wild animals. Currently, he is involved in a large and exciting research project examining the intersection between ecology and disease in the Gunnedah region.


Damien’s main area of research interest is the ecology and pathology of wildlife diseases, particularly the impact of human activities on the host-pathogen relationship of diseases in fragmented populations of two threatened species – the koala and the Australian sealion. He has a strong interest in fostering multidisciplinary and applied wildlife health research through communication and stakeholder engagement. His teaching reflects his diverse background and covers general pathology, laboratory disease investigation, wildlife disease ecology and management, and threatened species management.
