    Group of Molecular Toxicology      


    Dr. Yi-Jun Wu received his doctoral degree from the Graduate School of Chinese Academy of Sciences (Zoology) in 1995 and then he joined Institute of Zoology (IOZ), Chinese Academy of Sciences (CAS). He received his postdoctoral training in molecular biology in the Institute of Molecular Medicine and Genetics, Medical College of Georgia, Augusta, USA (1999-2001). In 2001, he rose to Professor in IOZ, CAS.

    Research Interest:

    Research in Dr. Wu’ lab (LMT) emphasizes the molecular mechanism of pesticides toxicity, which is important for understanding environmental chemical characteristics of pesticides, improving their selectivity, reducing the use of pesticides, and minimizing the hazards of exposure to humans, domestic animals, and other non-target species. Recent research involves four closely related topics, as described below.

    1. Mechanism of pesticide neurotoxicity on humans and other susceptible animals with an emphasis on organophosphate-induced delayed neurotoxicity (OPIDN)
    2. Study of multi-target joint toxicity of pesticides to help assess the environmental risk of pesticides
    3. Environmental safety of pesticides: Degradation of pesticides residues by genetically engineered bacteria
    4. Biochemical and molecular mechanism of resistance of insects to the insecticides
