My research interests focus on the causes and ecological consequences of variability in complex functions such as ontogenetic development, growth and behaviour. I have paid particular attention to the study of behaviour as the way animals interact with the physical environment and with other organisms. My scientific experience includes research on behavioural mechanisms involved in (1) avoiding predators (locomotion, social behaviour, escape responses) and (2) increasing reproductive output (mating tactics, reproductive investment).
Individual variability in performance constitutes the basis of key concepts in evolutionary biology such as adaptation and fitness. Particularly interesting is the study of complex functions that integrate genetics and physiology and have a direct effect on survival and eventual reproductive success. In this context, determining how environmental conditions (e.g. temperature) influence performance is essential to understand adaptation to changing environments.
