Researcher biography

I am a wildlife biologist interested in how species respond to a changing world. My main research interests involve utilising a range of methods such as line transects and camera-trapping to understand how species populations change through time, across disturbance gradients, and how species interact. Personal highlights from my career include understanding African forest elephant and great ape population changes through time in Cameroon and how feral cats and dingoes interact in Austral tropical rainforest. My role in CBCS’s Ecological Cascades Lab focuses on developing the Wildlife Observatory to facilitate Australia to understand critical issues around wildlife using robust datasets and cutting-edge analyses.
