Research areas
I am a quantitative ecologist based in the Centre for Research into Ecological and Environmental Modelling (CREEM) and the School of Biology.
I work on multiple aspects of the ecology, behaviour, physiology and population biology of marine mammals and other marine predators, at the interface between biology and statistics. I am interested in developing and applying robust analytical tools to quantify the relationships of these species with their environment and their interactions with human activities. In particular, a lot of my research so far has focused on the assessment of the effects of both natural and anthropogenic stressors on marine mammals, ranging from individual responses through to consequences for populations.
I strive for my work to inform policy makers, managers, and the industry, and therefore to support the sustainable use of marine resources and the long-term conservation of marine wildlife.
