Tim's research focusses on the interface between social and ecological systems and combines quantitative and qualitative methods to measure and understand human impacts on biodiversity. He is currently completing his PhD at the Interdisciplinary Centre of Conservation Science at the University of Oxford, supervised by Professor EJ. Milner-Gulland. Tim's PhD research focusses on the reliability of ranger-collected data on elephant poaching, and the motivations of the rangers and park managers that collect and use these data. Tim graduated with a BSc in Mathematical Statistics in Zoology from Rhodes University, South Africa, before completing an MSc in Biodiversity Conservation and Management at Oxford University. Tim has worked as a data analyst for the Wildlife Conservation Research Unit at Oxford, and as a programme officer for elephant monitoring and management at Hluhluwe-iMfolozi Park, South Africa. Tim has previous research experience on large carnivore attacks on domestic livestock, the sustainability of lion trophy hunting, and the reliability of indices of elephant poaching. He has learnt that diverse methods (from interviews to mathematics) are essential to understanding complex-human nature systems and generate knowledge that is useful for conservation practitioners.
