Research Interests

My research focuses on the understanding how species and communities respond to land use, land-use change, and changes associated with various management decisions. In particular, I have been investigating how species (e.g. lion and elephant) respond to different types, policies, and practices of land-use, and management decisions across a spectrum spatial and temporal scales. From a broader ecological perspective, I have been conducting research on how animals, for example ecosystem engineers such as elephants, affect populations and communities of other sympatric species (e.g. bats, rodents and shrews) and how these other species respond; or whether these mammals are affected by different impacts or processes such as land use (e.g. agricultural, mining, urbanization), and land-use change (e.g. bush encroachment), and management decisions (e.g. re-introduction of lion and elephant etc.). Early findings of my current studies point to several drivers that ultimately define how species/communities are structured, and the subsequent, often very specific responses to certain land-use conversions. The ultimate driving factor, however, seems to be the continued impact of the land-use legacy, which appears to be the long-term driver defining the species and community responses, including behavioural, to recent management decisions. I have benefitted greatly from collaborative work, providing invaluable opportunities for my own research development, and opportunities for my post-graduate students. As result, I have been working on a large range of mammalian species, from little rodents to mega-herbivores, to coastal cetaceans. This broad comparative, and collaborative research has been most exciting; working with established and strong researchers have allowed me to refine my own research skills and approach which leads to improved research outputs.
