My research mainly focuses on different aspects of enteric viruses fate in the water ecosystem. It starts with enteric virus detection in wastewater, drinking water, surface water and reuse water continue with their survival and removal in the water/wastewater treatment. My other interest is enteric viruses evolution related to their resistance to disinfectant. For public health aspect, I do the quantitative microbial risk assessment to measure the risk of infection of targeted enteric viruses with specific contact scenario with the human population.
