Research Interests

Two interlinked research areas are pursued in my laboratory focusing on freshwater and marine fish and invertebrates:

(1) Physiology of metal homeostasis and toxicity in different aquatic environments.

(2) Physiology of hydromineral balance in freshwater, brackish water and marine environments.

Homeostasis of essential and non-essential metals in fish and invertebrates are in focus in my laboratory. We study mechanisms of metal uptake, metabolism and excretion as well as the toxic response resulting from elevated environmental metal concentrations. The metals currently being studied included copper, silver and lead.

Fish and invertebrates are able to osmoregulate in environmental ranging from very dilute freshwater to highly saline seawater and offer a range of organs specialized in maintaining extreme ionic gradients. While detailed studies of the special epithelial traits involved in these functions is important to understand how these animals interact with their environment, they may also offer valuable information about specialized human epithelia like the exocrine pancreas, the human colon and the renal tubules.
