Welcome! My laboratory explores the how's and why's of physiological design. Our primary interests are in energetics and digestive and cardiovascular systems. We examine the adaptive and integrative design of organ morphology and function. Our projects usually fall under two long-term interests: (1) the adaptive interplay between feeding habits and digestive physiology, and (2) the integrative mechanisms underlying the regulation of physiological performance. For the former project, we take a broad comparative approach using fishes, amphibians, and reptiles to investigate the evolutionary link between natural feeding frequency and the capacity to regulate gastrointestinal performance. The second program uses the Burmese python model to identify the signals and cellular pathways involved in the plasticity of tissue structure and function in response to fasting and digestion.
