Joshua P Twining

Research Scientist in Population Ecology at Cornell University and Postdoctoral Reseacher, Queen's University Belfast

Joshua Twining is a population ecologist interested in mammals and birds. His research currently focuses on the modelling species interactions and how these impact occurence and abundance of animal populations in order to inform their management and conservation. Current projects range from impacts of expanding coyote populations in eastern North America, to interactions between pumas, Andean bears, and tayras in Ecuador.

He sits on the Mammal Society Scientific Advisory Committee, as well as the Steering Group for Magical Mammals.

Twining completed his PhD at Queen’s University, Belfast where he was based since 2016. Before this he worked with the People’s Trust of Endangered Species under David Tosh. He completed his Masters by Research at Imperial College London after spending a number of years working on various wildlife research projects in Indonesia and Malaysia.
