Our history
The UniSC Detection Dogs for Conservation team was founded in 2015. They saw massive potential in using detection dogs to protect and preserve Australia's unique wildlife, many species of which are now under threat. UniSC’s DDC is the only university research group which rescues, trains, tests and deploys detection dogs for conservation in Australia.
Co-founder Dr Cristescu is also an executive member of the Australian Conservation Dog Network, which includes representatives from universities, non-profit organisations, governments, zoos, research institutions and businesses.
Our researchers
Dr Romane Cristescu
Dr Romane Cristescu is the Director of Detection Dogs for Conservation and a Research Fellow at the University of the Sunshine Coast. She is a conservation ecologist with a wide range of interests - all centred around this single and complex question: “how can we best help wildlife in a world dominated by humans?”
Romane believes robust science is necessary to support good decision making, and she is especially keen to test that legislation is grounded in science and effectively delivering conservation outcomes. Her methodology and legislation work has been specifically focusing on koalas.
Romane is a qualified veterinarian and originally worked on conservation genetics before moving to Australia for her PhD in landscape ecology. She worked in the Mining Industry on Mine Closure / Rehabilitation, where she transformed her research on restoration ecology into practice. Since then, she continued working with the private sector, as well as the Government, not-for profits and Academia – by interacting with a wide range of stakeholders, understanding their constraints and aspirations, Romane hopes that her research can be transformed into informed and effective policy, investments and management actions. Since its creation in 2015, the Detection Dogs for Conservation team has grown to include five detection dogs and many dedicated students and researchers.
Dr Katrin Hohwieler
Katrin did her PhD with the Detection Dogs for Conservation team and graduated in 2021. In her PhD she investigated how anthropogenic impacts such as fragmentation can show in genetic patterns of threatened koala populations. She now conducts research building further on her PhD studies and expanding into other areas of interest around threatened species conservation.
In her spare time Katrin enjoys birdwatching, wildlife photography and travelling. Katrin works and lives with Billie Jean, who is her absolute favourite of all dogs.
Skills
Conservation genetics, population genetic analyses, genetics from non-invasive scats, QGIS, INLA analyses, community engagement, science communication, detection dog handling, project management, fieldwork, data collection
Dr Riana Gardiner
Riana did her PhD at the University of Tasmania, and once she was done was quick to join the Detection Dogs for Conservation team. Riana is interested in how animals interact with their habitat, and how we can use this information to better inform management.
Her current research investigates how hormones from non-invasively collected koala scats can help inform koala conservation management. She loves being in the field with her favourite – Bear. Riana is one of his handlers and together they have spent many hours in the field, especially after the Black Summer Fires in 2019/2020.
Skills
Landscape Ecology, ArcGIS, hormones from scats, statistical analyses, detection dog handling, project management, fieldwork, data collection
Dr Ajith Horane Karayalage
Skills
Caio Santos Neto
Caio Santos Neto is a PhD student interested in understanding how anthropogenic disturbances and landscape changes impact biodiversity. By integrating threats, management actions and population dynamics he aims to help decision-makers to develop more cost-effective conservation plans.
Currently, he is working with koala populations that inhabit urban and semi-urban areas in South East Queensland.
Skills
Movement data analyses, QGIS, detection dog handling, community engagement, VHF radiotracking, fieldwork, data collection
Asitha Samarawickrama
Asitha is an Environmental Scientist who recently completed his Master of Science with the DDC. Asitha investigated how koala densities and stress responses changed in response to Cultural Burns on Minjerribah, North Stradbroke Island. In his spare time you can find Asitha playing cricket, tennis or in the bush searching for wildlife.
Skills
VHF radio tracking, ecological assessments, fieldwork, data collection, koala ground capture and trapping, fauna identification, data analysis from drone imaging, science communication.
Russell Miller
Russell is a dog handler and has been a trainer of detection dogs since 2011 specialising in koala and quoll. He has completed many ecological surveys across Australia and New Caledonia, and trained and deployed dogs to detect species such as koala, quoll, numbat, Tasmanian masked owl and New Caledonia crow.
Russell has been responsible for the delivery of numerous consultancies, training of detection dog and their handlers, the fitness and wellbeing of the detection dogs and supports the team in the field and other operating tasks.
Skills
Detection dog training, detection dog handling, fieldwork, data collection
Cedar Staggard
Cedar is a current honours student, investigating the efficiency of non-invasive genetic capture-mark-recapture of koalas. During her Animal Ecology degree she undertook a research project with the team exploring the efficacy of qPCR screening for Chlamydial pathogens on genetic material non-invasively sourced from koala scats.
She is passionate about all wildlife and conservation of species and habitat, when she’s not out in the field or in the lab you’ll find her on the netball court or out searching for creatures.
Skills
VHF radio-tracking, DNA extraction, genetic analysis, field work, data collection, wildlife rescue.
Dr Alexis Levengood
Alexis is a behavioural ecologist and geneticist. She supports the team with her extensive knowledge in data analysis and in the laboratory. She also works in the field regularly radio tracking koalas.
Skills
Genetic analyses, VHF radio tracking, fieldwork, data collection
Kye McDonald
Kye is a current doctoral researcher studying new innovative technologies that can support and advance wildlife conservation.
Skills
Drone operating, conservation technology, koala catching, detection dog handling
Imogen Dumville
Imogen is a current PhD student from NZ, focusing on the impact and interaction of threats on koala population health. She will investigate the roles of chlamydia, habitat loss and anthropogenic activity with the aim to develop non-invasive genetic tools to improve monitoring and conservation.
Imogen is passionate about applied conservation of biodiversity and the benefits of public engagement with governmental policy. When not in the office, you’ll find her in the sea, rock climbing or hiking the hinterlands.
Skills
Conservation Genomics and Analysis, Disease Genetics, Fieldwork, Conservation Engagement
Dr Deidre de Villiers
Deidre is a passionate ecologist and koala conservationist and has been working with koalas for over 24 years. During this time she completed a PhD investigating urban koala populations, including their distribution and abundance, habitat utilisation, conservation requirements and threat mitigation.
In her spare time, she cares for juvenile koalas orphaned as a result of disease and anthropogenic threats that lead to the death of the mother. Her work aims to better manage and recover these urban koala populations.
Skills
Project management, Radio telemetry, koala catching and handling, data management, population surveys and monitoring methods, conservation planning and policy.
