Research Interests

My scientific research work is in the field of biochemical environmental toxicology. It is focused on the study of cytochromes P450, acetylcholinesterase, phase II detoxifying enzymes in wildlife. Major attention is given to the interaction of environmental pollution with reproduction of marine and terrestrial organisms. My lab also developes methods and technology for the detection of low levels of organophosphorus and carbamate residues in fresh water.  Research activities include:

  • Study of cytochromes P450 in species of different Phyla.  
  • The interaction of environmental pollution with reproduction.
  • The development of biochemical method for the detection of low levels of organophosphorus and carbamate insecticides in fresh water using acetylcholinesterase profile in fish.
