Dr Holden is a Lecturer and Research Fellow at the University of Queensland in the Centre for Applications in Natural Resource Mathematics and the ARC Centre of Excellence for Environmental Decisions.
He develops quantitative approaches to solve challenging problems in environmental management. This includes how to cost effectively search for invasive species, save threatened species, protect natural ecosystems, and harvest fish sustainably. He is currently conducting the first ever stock assessment for Torres Straight coral trout and is also studying the dynamics of illegally harvested wildlife (e.g. elephants poached for ivory).
