My PhD research was about the modelling and testing the effects of landscape fragmentation on habitat selection by a songbird, the European nuthatch. After my PhD research, my research focuses broadly on ecological and evolutionary adaptations of animals to stress (e.g. pathogens, poor food quality, predators, high temperatures, humans). Environmental stresses can constrain movement and searching for habitat and food, such as the presence of predators and exposure to extreme ambient temperatures or periods of drought. As a consequence, constrained movement can result in suboptimal choices in foraging and habitat selection. This is studied in a variety of systems, varying from mammalian herbivores to insects.
