Research interests

My research lies at the intersection of population biology, animal behavior and conservation where I focus on addressing practical aspects of wildlife management and conservation problems. At the University of Glasgow, I work with Dr Grant Hopcraft and Prof. Dan Haydon on the EU Horizon 2020 African BioServices project to understand the causes and consequences of large mammal migration in the Greater Serengeti Ecosystem. Much of my past work has examined how large vertebrates respond – demographically and behaviorally – to changes in their landscape caused by humans. I use an array of analytical tools and ecological methods to address these questions, and whenever possible, I rely on theoretical (sometimes even mathematical) models to broaden the generality of results. While much of my research focuses on migratory ungulates, I am a broadly trained ecologist with interests in how animal and plant populations respond and adapt to environmental variation and disturbances.

Current Projects:
African BioServices: Based in the East African Serengeti-Mara Region, this project aims to unravel how human activity (population growth, land-use change) and climate change impact key ecosystem services, i.e. the benefits humans derive from natural ecosystems and their associated biodiversity. The project will look at how such impacts affect human wellbeing and exacerbate poverty, with the aim to derive novel sustainable solutions that will protect biodiversity, and improve the benefits that people derive from the unique ecosystems within the region.
