Peter is Research Leader, Predator and Prey Management with NSW Department of Primary Industries. His principal research interest is the adaptive management of invasive animals, particularly dealing with "wicked problems" such as predator conservation and control, and feral ungulate harvesting and control, and all while integrating social, economic and environmental values. Peter's current study mammals include macropods (brush-tailed rock wallabies are particularly delightful), spotted-tailed quolls, dingoes, red foxes and feral cats.
