Arising from my predoctoral and postdoctoral trainings, my research experience centers on Applied/Industrial Microbiology with focus on the following:

(a) detection, characterization and elimination of food-borne pathogens-involving use of phenotypic, chemo-taxonomic, genetic and epidemiological methods;

(b) detection, characterization and reduction of microbial metabolites in foods particularly aflatoxins;

(c) food biotechnology with respect to selection, characterization and utilization of environmentally-friendly, biodegradable and natural plant additives for foods; plasmid profilling, isolation of DNA and proteins (including heat shock proteins) from microbes; use of restriction enzymes (endonucleases), gene cloning and transformation experiments; food fermentation and application of hydrostatic pressure for food preservation /processing;

(d) establishment and monitoring of hazard analysis critical control points (HACCP) in food industries; (e) detection of food-borne parasites like flukes and cestodes. Working experience in medical technology with particular reference to medical microbiology/microorganisms associated with diseases.
