I study the responses of natural systems to human impacts such as species invasion, habitat destruction, fishing pressure, etc. I am particularly interested in how these activities influence biodiversity within species (i.e., the diversity of functional traits seen within species). The overarching goal of my research is to improve our ability to predict the responses of populations and communities to future human impacts. I generally take a bottom up mechanistic approach, determining how behavior, physiology, and morphology facilitate or constrain the responses of individuals to environmental change, and how those individual level responses then scale up to establish patterns and processes at the population and community levels.  I do this using a variety of approaches, including field observations, field and laboratory experiments, physiological measurements, and computer simulation modeling.

While addressing questions of environmental change described above, my research simultaneously provides insight into fundamental aspects of organismal biology and physiology and into consumer foraging that is central to all ecological communities. Finally, my research also addresses areas where results can be applied to enhance management and conservation efforts.
