Dr Christopher O'Bryan

Postdoctoral Research Fellow

School of the Environment
Faculty of Science


Chris works on a broad range of topics related to conservation biology. His recent work is focused on invasive species management and how governments can make better decisions to maximise cost-effectiveness to protect biodiversity and social values.

Chris also researches human-wildlife conflict and coexistence, and he has developed a series of global spatial analyses that illustrate the effects of human footprint on threatened species and their habitats. His research has been published in a number of high-impact journals and has been featured on media outlets such as The Guardian, ABC News, Scientific American, and The Conversation.

Before his work at UQ, Chris was a Wildlife Biologist for the State of Florida in the USA where he developed habitat management plans and liaised with private landowners on conservation easement lands. He has a PhD in Conservation Biology from UQ, an MSc in Wildlife and Fisheries Biology from Clemson University, and a BA in General Biology from Austin Peay State University.
