My research interest is in the interface between behavior, nutrition, ecology and animal performance. Understanding the relationships between nutrition, behavior, ecology, morphology and physiology is a central aim in nutritional ecology. Nutrition is a complex process that involves mixtures of nutrients parceled at different ratios that fluctuate in dynamic environments. Foragers have continuously adapted to these changes to meet their own nutritional requirements.

My current fields of research span a range of species (including fish, marine and terrestrial birds and marine and terrestrial mammals), research habitats (marine and terrestrial), contexts (lab, field and modelling) and objectives, both theoretical (e.g. multi-nutritional niche concept) and applied (cutting edge techniques, pollution and wildlife, climate change, biological invasions, urbanization and wildlife and wildlife conservation).
