Joshua P Twining

PhD researcher in Ecology, Queen's University Belfast

Joshua Twining is a conservation biologist who studies the ecology of recovering predator populations. His research currently focuses on monitoring the recovery of the European pine marten in Ireland, how important these predators are in structuring the ecosystems they inhabit, and their propensity to recover in human-modified landscapes.

Twining is finishing his PhD at Queen’s University, Belfast where he has been 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 with Robert Ewers and Samrat Pawar, after spending a number of years working on various wildlife research projects in Indonesia and Malaysia.

Twining has worked mainly on terrestrial systems, from colourful skinks to sun bears, and examines the response of species and communities to anthropogenic processes.
