Biography

My research to date has used field, experimental and comparative approaches to yield novel insight into how reproductive competition and conflict have shaped vertebrate (primarily mammalian) morphology, physiology and behaviour. To help achieve this I have developed expertise in the generation, maintenance and analysis of powerful relational databases covering multiple aspects of individual life histories (or species traits), such as their morphology, sociality, aggression, hormone profile and ejaculate characteristics. Currently, I am using multi-generational databases on North African Houbara bustards (>4000 individuals) and St. Kildan Soay sheep (>1000 individuals) to examine the endocrinological determinants of reproductive effort and its influence on the evolution of senescence rates, in addition to how gametogenic senescence hinders the developmental success, growth, and subsequent survival prospects of progeny. Overall, my research draws upon long term collaborative studies and utilises sophisticated statistical methodologies to investigate evolutionary processes at a mechanistic level.
