Research Interests

Increasing human driven pressures on natural systems are causing major ecological changes from the alteration of species life history strategies to, in the worst case, population collapse. The long term impacts of these changes on species survival and ecosystem functioning are largely unknown. Research in my group strives to provide greater understanding of the factors influencing ecosystems and the manner in which species respond to these influences, with the ultimate aim of providing empirical based information and strategies to address the many conservation challenges we face today. We work to actively translate these research outputs into policy and conservation actions.

Current Research Directions


-        Influence of Ecological Dynamics on Population Spatial, Demographic, and Social Properties


-        Movement Ecology


-        Human-Wildlife Interface

-        Conservation Policy

-        African Elephants and other large mammals
