Our lab is broadly interested in comparative physiology and biochemistry, with an emphasis on how cellular processes affect complex, whole animal phenotypic traits. Much of our effort at the cellular level is directed at understanding muscle energetics and the metabolic principles that drive cellular design. That is, we try to understand how biochemistry works in living cells, accounting for such features as metabolic organization and intracellular diffusion. Our studies of muscle function are then used to define aspects of whole animal behavior, such as the limits to burst escape locomotion or exercise endurance. We study marine invertebrates (such as crabs and lobsters) and fishes because of the extreme diversity in structure and function found in tissues from these organisms, as well as mice, which are excellent biomedical models. We use several experimental techniques that allow us to non-invasively probe metabolism in living cells, including nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), and confocal microscopy, as well as invasive approaches such as cDNA microarray analysis, spectrophotometric assays, muscle contraction measurement, and electron/light microscopy.
