Research

My general research interests are in interdisciplinary areas linking chemistry and toxicology techniques to their environmental applications with the objective of understand ecological risk of environmental contaminants in aquatic ecosystem. I am primarily interested in addressing research questions about environmental fate and adverse effects of organic contaminants, with a particular focus on bioavailability and toxicity of current-use pesticides in sediment. Identifying the principal cause of toxicity in the presence of multiple stressors using toxicity identification evaluation techniques is also of my special interest.

My current projects include understanding the influence factors of bioavailability of contaminants in sediment, evaluation of bioavailability and toxicity of organic contaminants by biomimetic techniques, and investigating joint toxicity of sediment-associated contaminants.

I currently serve as an editor board member of Integrated Environmental Assessment and Management and TheScientificWorldJOURNAL.
