I graduated from the University of Southampton with a BSc in Zoology in 2011 and soon after undertook a research internship with Save the Elephants in Kenya. I then completed an MRes in Ecology, Evolution, and Conservation at Imperial College London in the autumn of 2013. Subsequently, I started my PhD at the University of Edinburgh, supervised by Dr Per Smiseth, Prof Alastair Wilson, and Prof Josephine Pemberton. My PhD focused on understanding how between-individual differences in movement and genetics contributed to variation in reproductive traits in female St Kilda Soay sheep. Post-PhD, I took a postdoctoral position at the University of Saskatchewan, Canada, where I explored the consequences of variation in the social environment for individual movement, fitness, and population dynamics in Sable Island horses (NSERC-funded grant awarded to Dr Philip McLoughlin).

Research Interests

Broadly, my research focuses on how individual differences, whether genetically or environmentally derived, influence the performance of wild organisms and thus affect population and evolutionary dynamics in natural populations. More specifically, I am fascinated by movement behaviour, both in terms of the drivers of movement patterns and the fitness consequences of movement decisions. Recently, I have become intrigued by the phenotype-dependence of movement behaviour and the resulting potential for individuals to use movement to match their phenotype to their environment. I study these questions using the exceptional data available from long-term individual-based studies of wild animal populations and a variety of methodological and analytical approaches from fields including movement ecology, quantitative genetics, and behavioural ecology.
