Brief synopsis of current research:
My current research describes how physiological processes are altered in fishes as they develop. At different life stages (e.g. embryo, larva, juvenile, adult) fishes may experience changes in organ structure, environment, food preferences, and reproductive status. These changes may influence a wide variety of physiological processes, including nitrogenous waste metabolism, gas exchange, gill ion transport, and acid-base regulation. Accordingly, I use physiological, biochemical and morphological approaches to describe how these processes are altered during a fish's life cycle. Although, I am interested in other fish species, including salmonids, flatfish and elasmobranches, lampreys are the experimental model for much of my work because of their highly complex life cycle. My present research describes how patterns of nitrogenous waste excretion and production change during different points in the life cycle of the sea lamprey (Petromyzon marinus). Due to the lamprey's ancient lineage, my work also addresses questions pertaining to the evolution of physiological processes in vertebrates.
