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 medaka (Oryzias javanicus) and tilapia (Oreochromis sp.), sex changes in Thais, and the quality of feeding habitat for migratory shore birds and other coastal wildlife.

Marine Biology and Ecology
Research in Marine Biology and Ecology involves the group of scientists within Biology Department, Universiti Putra Malaysia and other local universities as well as international biologists and ecologists from marine, freshwater and terrestrial backgrounds, with research interests ranging from genetic of individual organisms to functional processes in local marine ecosystems. This broad research base provides the opportunity to address novel and topical issues related to local marine environment and contributing to the science of tropical marine ecosystem.
Research activities involves observations and experiments in both field and laboratory environment. The research including the discovery and understanding of the basic biology of marine plants and animals, environmentally-controlled laboratories such as behavioural, developmental, biochemistry and ecophysiological studies on marine life such as fishes, prawn, crabs and other plants species such as seaweeds and sea grasses and their function and interactions within marine communities. These involve the development of marine plants as indicators of water quality, the influence of nutrient enrichment on seagrasses, the roles of nitrogen fixation and sulfate reduction in seagrass growth, carbohydrate and fluorescent responses of sea grasses to changes in light and nutrient regimes and the effects of nutrient enrichment on tropical marine systems, systematic and dynamic of benthic and planktonic organisms in sea grasses ecosystem, toxicological studies on the coastal ecosystems, including mangroves and sea grasses, marine aquaculture, marine parasitology and techniques in marine and freshwater aquaculture, and marine conservation.

Ecotoxicology
Research focuses primarily on the evaluation of pollutant-induced effects on aquatic animals. This involves the detection and understanding the fundamental mechanisms by which pollutants cause’s biological effects. In general Ecotoxicology research group works on the areas of ecophysiology, biomarkers, mechanistic studies, immunotoxicity and endocrine disruption at different levels of biological organisation including invertebrates and wildlife.
Among the specific works are; trace element metabolism in aquatic invertebrates, especially the effect of physiological and biochemical parameters (the sex, the reproductive status and, in crustaceans/molluscs, the moult stage, detoxify trace metals) on trace element distribution and toxicity, endocrine disruption in fish - with emphasis on the oestrogenic (and other endocrine disruptors) effects on gonads development and histology of java medaka (Oryzias javanicus), tilapia (Oreochromis sp.) and rock snail (Thais sp.), arsenic and mercury in aquatic ecosystems and seafood, examines the absorption of metals (copper, zinc, lead, cadmium, mercury, tin – including tributyl tin) and metalloids (arsenic and selenium) from water, sediments, and food, and investigates their subsequent distribution, metabolism, and excretion, identifying the mechanisms (including the forms of chemicals occurred in the environment – sediment, water, algae, and their bioavailability) by which non-essential metals and excess amounts of essential metals adversely affect the animals.
These researches are carried out in collaboration with other research groups within the Department of Biology, other institutes/universities in Malaysia and other academic and governmental organisations both national and international.
