About

Since last thirty seven years, I am actively engaged in teaching of theory and practical of under graduate and post-graduate classes. Courses teaches by me in under graduate classes are type study of two phylum Mollusca and Echinodermata while biological biochemistry, animal behaviour and fishery biology in post-graduate classes.

The research work in my laboratory currently focuses on studying the mechanism of control of vector snails and mosquito larvae through natural as well as synthetic pesticides and in order to study the environmental toxicity by these pesticides, the toxicity, biochemical, physiological and genotoxic experiment were carried out on freshwater fish over the last thirty seven years. A number of new methods have been developed in my laboratory for the extraction of natural compounds from plants, which were found effective against molluscs, fishes and mosquito larvae. Furthermore a number of biochemical methods have also been established for the studies of toxicological effects of pesticides on various metabolically vital enzymes such as acetylcholinesterase, succinic dehydrogenase, lactic dehydrogenase, cytochrome oxidase, protease, phosphatases and transaminases etc. My laboratory also studied the effect of toxicants on reproduction and post-embryonic development of mosquitoes as well as fecundity, hatchability and survival of snails.

During this period my laboratory has published four review papers, Twelve book chapters in edited books and one hundred seventy four (174) research papers in journals of international repute (like Acta Hydrochim Hydrobiol, Chemosphere, Journal of Ethnopharmacology, Fitoterapia, Environmental Research, environmental toxicology and pharmacology, Pesticide Biochemistry and physiology, Ecotoxicology and Environmental safety etc. (Impact Factor ranges from 0.5- 4.0) and Twenty Eight (28) students obtained Ph.D. degree.

Another side, Eleven major research projects have been sanctioned from different organization like Department of Biotechnology, New Delhi, Department of Environment and Forest, New Delhi, Indian council of Agricultural Research, New Delhi, University Grants Commission, New Delhi, Council of Science & Technology U.P., Lucknow, Council of Scientific and Industrial Research, New Delhi and Indian Council of Medical Research, New Delhi.
