My research focuses on the effects of environmental change on wildlife behaviour, populations and distributions. By combining contemporary ecological techniques with an understanding of resource-consumer dynamics in heterogeneous environments, I aim to gain mechanistic, process-driven understanding of ecological systems through both statistical modelling and more applied, management-orientated experiments. I am particularly interested in methods for scaling up from the mechanisms underlying individual behaviour of wildlife to understand and predict population and ecosystem level consequences in rapidly changing, complex environments.
Currently, I am using large-scale datasets to explain and predict impacts of environmental change on biodiversity. We are working to model vector borne-disease systems for plant and animal pathogens (Phytophthora; bluetongue virus). I am also working to understand the consequences of offshore renewable energy developments on seabird populations, as well as how extrinsic and intrinsic processes drive the distribution, abundance and population dynamics of seabird species in UK waters.
2010 to date: Ecological modeller at CEH, Edinburgh.
2007-2009: Post-doctoral research (Natural Resource and Ecology Lab, Colorado State University). Research into the effects of fragmentation on consumer-resource dynamics in environments varying in space and time. Also, collaborative research with Colorado Division of Wildlife using remote-sensing to predict diet quality and body condition of mule deer in western Colorado in response to temporal and spatial variation in plant phenology and climate. Also worked with USGS Ecosystem Dynamics Group to develop a hierarchical Bayesian analysis of the population dynamics of the San Luis Valley bison herd.
2005-2007: Post-doctoral research at CSIRO, Sustainable Ecosystems Division. Conducted research on the impact of cattle grazing on spatial patterns of vegetation and soil components in grazed semi-arid rangelands, with implications for ecosystem function and integrity. Additional research on the influence of variation in predation risk and food resources on the foraging behaviour of small mammals.
2000-2004: PhD (Colorado State University, National Science Foundation funding) on the role of spatial heterogeneity in foraging decisions of large herbivores.
1995-1999: BSc First Class in Ecology, University of East Anglia.
