Personal information

Biography

I am an Environmental and Public Health Microbiologist, skilled in the application of molecular techniques, microbial risk assessment and bioinformatics, and in the relational style of teaching. My primary research interests include Aquatic environments and human health, Quantitative microbial risk assessment (QMRA), Water, sanitation and hygiene (WASH), Molecular epidemiology water pathogens, Antimicrobial resistance (AMR) and dispersion of antibiotic resistance genes, Wastewater-based epidemiology (WBE), Bioactive agents from plants and aquatic systems, and Bioenergy and biochemicals from wastewater. My professional goals are to continue to acquire skills and knowledge, to do and publish quality research, to seek and establish international collaborations and secure funding for research, and to build a Laboratory that will, on the long-term, emerge as a Centre of excellence for water pathogen and molecular epidemiology research. A confident, self-motivated, result-oriented and resilient team-player, I lead the multidisciplinary Water and Public Health Research Group (WPHRG) at the University of Nigeria, Nsukka, Nigeria.
