Dr Christopher OBryan
Postdoctoral Research Fellow
School of Earth and Environmental Sciences

Researcher biography
I have a background in spatial ecology, landscape-scale conservation, and decision science ranging from studying reptile movement patterns and habitat selection to working on private land management practices and making structured environmental decisions. I received my PhD at the University of Queensland in 2020 investigating the exposure and contribution of carnivores to humans. I have studied the unrecognised benefits of predators and scavengers in human-dominated landscapes and the unique contribution of apex scavengers to ecosystems and human health. Since the completion of my PhD, I have worked as a postdoctoral researcher focusing on helping government make decisions to maximise their resources for effective conservation.
