The primary goal of my research program is to investigate environmental adaptations (both mechanistic and evolutionary) in relation to gas-exchange, acid-base balance and ion regulation in fish, integrating responses from the molecular, cellular and organismal level. The ultimate goal is to understand how evolutionary pressures have shaped physiological systems among vertebrates and to determine the degree to which physiological systems can adapt/acclimate to natural and anthropogenic environmental changes. This information is crucial for basic biology and understanding the diversity of biological systems, but much of my research conducted to date can also be applied to issues of aquaculture, toxicology and water quality criteria development, as well as fisheries management.
