Research Interest

Research area is effect of hazardous chemicals in the environment. Focus of research includes the distribution and toxicity of heavy metals (Cu, Pb, Zn, Cd, and Hg), endocrine disruptor such as estrogen and tributyl tin in the aquatic environment (fresh water lakes and rivers and coastal ecosystems). Among the activities is identification of specific intertidal molluscs/crustaceans as a monitoring agent for heavy metals, effect of those hazardous chemicals on the gonad development, reproduction and histology of fish java medeka (Oryzias javanicus) and tilapia, sex changes in Thais, and the quality of feeding habitat for migratory shore birds and other coastal wildlife.
