RESEARCH INTERESTS
Research currently focused on investigating (1) the kinetics and biotransformation of pesticides, aromatic hydrocarbons, and natural toxins in aquatic animals; (2) the influence of surfactants on the bioavailability of petroleum hydrocarbons in aquatic systems;(3) the biochemical actions of pesticides in aquatic animals using nuclear magnetic resonance (NMR)-based metabolomics;(4) the fate of pesticides and petroleum hydrocarbons in marine mussels and sediments; (5) the toxic influence of surfacants and petroleum hydrocarbons on marine larval development; (6) characterization of glutathione S-transferases in fishes; (7) dissipation and fate of pesticides in rice fields.
