Dr Widad binti Fadhullah is a senior lecturer at the School of Industrial Technology, Universiti Sains Malaysia, Penang. She received her degree in Biodiversity Conservation and Management in KUSTEM, or currently known as UMT and her MSc in Conservation Biology, UKM. She completed her PhD in Environmental Science at University of East Anglia, Norwich, UK working on nitrogen biogeochemistry in aquatic ecosystem. She has attended several national and international courses; one of them is Application of Environmental Isotopes in Rivers and Lakes organized by IAEA, Isotope Hydrology Section, Vienna. She has conducted fieldwork in rivers and reservoirs in Penang, Perak and landfill in Kelantan. Her main background is related to water quality monitoring and assessment in freshwater ecosystems. Widad has presented her work and gave talks at both national and international venues.

RESEARCH INTEREST

My previous research experience started from doing capture-recapture and tagging techniques of fruit eating bats in KUSTEM campus area. I was lucky to be one of the participants in a program 'Bat Identification and Survey Techniques' held by Malaysian Bat Conservation Research Unit led by Dr. Tigga Kingston in Lanchang, Pahang. After that, my research journey continued to the world of aquatic ecosystem by conducting fieldwork sampling of freshwater fishes from Sungai SImpang Empat, Penang. From here, I learned how to analyze fish tissues for heavy metals analysis. Then, my research expanded to estuaries in Breydon Water, Great Yarmouth, UK to have an experimental microcosm setup involving short term effect of hypoxia and anoxia on nitrogen biogeochemistry.

Currently, my research interest revolves around river monitoring and assessments, integrating water quality, nutrient and heavy metals concentration as well as water and nitrate stable isotopes in freshwater aquatic ecosystem. Apart from the water component, the sediments and biota in the ecosystem are also incorporated in my research to understand the effect of water quality and nutrient changes to living organisms such as aquatic plants and fishes.
