I joined the College of Public Health's Division of Environmental Health Sciences in September 2008. I was recruited as part of the Targeted Investment for Excellence, Public Health Preparedness for Infectious Diseases (PHPID), and I have a joint appointment with the Department of Food Science and Technology. My laboratory seeks understanding  the transmission of waterborne and foodborne pathogens from contamination sources, transport in environments, and exposure to humans. We use molecular technology, such as microbial source tracking, and interdisciplinary apporoach, including One Health.  

Mission of Environmental Microbiology and One Health Lab (EMOHL)

 Through scientific discoveries that we accomplish at the EMOHL, we contribute to creating healthy environments for people across local, national, and global community. The EMOHL members achieve our professional goals together as a team by helping each other, enriching team members, practicing outstanding work ethic, and aligning our research to societal needs in improving and protecting environmental and human health.

Research Interests

My primary research areas are key issues in environmental microbiology with public health significance focusing on understanding the pathways of pathogen transmission from the contamination sources to human exposure, including water and farm to fork food chain. For this, we use molecular and metagenomic tools to investigate the microbial community structure in environments and hosts, statistical tools to understand the relationship between environmental factors and microbial populations, and often develop new methods for the detection of target microorganisms and thier toxins. My recent study sites include Sugar Creek, inland lakes in Ohio, Lake Erie, fish farms in China, and Cameroon.

I am particularly interested in the impact of climate change, inlcuding extreme weathr events, on the transmission, fate and virulence of enteric infectious agents and cyanobacteria (cyanotoxins). My lab also work on emerging health risks due to exposure to environmental contamination (e.g. zoonotic agents, cyanotoxins) via varous exposure routes with ecological and epidemiological approaches.  For interventions, we develop environmentally friendly and sustainable strategies using beneficial microbes and non-chemical based methods.The knowledge and research outcome from my lab is applied to identify health hazards and influencing factors. Our tranlational research provides more effective ways of management to mitigate public health risks and can be helpful for policy making.
