My research focuses on the functional, ecological, & evolutionary aspects of how vertebrates detect, acquire, ingest and digest food. My program is integrative and comparative in nature. This work falls within the conceptual framework of ecological morphology & physiology and is conducted at the functional organismal level (morphology and physiology), behavioral, and ecological levels. The central concept of this field is that morphology and physiology influences an organism's ecology through constraints of behavioral performance, which is the capacity of an animal to exploit its natural resources, and explore its environment. Although investigations of morphology, physiology, and behavior stand on their own, ultimately the integration of these studies can explain how organisms interact with their environment, the evolution of functional complexes, and the pressure selections involved in driving adaptations.
