1. Environmental signal transduction: This area focuses on how an environmental signal can result in selective gene activation, using salinity-mediated induction of carbonic anhydrase expression in the gills of euryhaline organisms as a model experimental system.
2. Environmental toxicology: We have recently initiated a study on the effects of heavy metals on carbonic anhydrase activity, the enzyme's physiological role in ion transport and regulation, and its expression in euryhaline crustaceans.
3. Bimodal breathing: This is an ongoing project studying the transition from gill to lung breathing in amphibious crustaceans, the mechanisms of respiratory gas exchange and acid-base balance in water and air, and the control of ventilation.
