Summary

My research focuses on building capacity and capability to respond to environmental public health issues as they arise in Wisconsin. At the present time the important issues are; developing a sensitive test for and performing screening of waters for E. coli O157, improving Cryptosporidium detection methods, identifying sources of Cryptosporidium in watersheds, developing a test for and performing screening of drinking waters for Helicobacter pylori, studying the movement of microbes through soil beneath wastewater treatment facilities, developing methods for detecting endocrine disruptors in water and improving our understanding of microbial indicators of water pollution. Emerging areas of interest include antibiotic resistant bacteria in the environment and mycobacteria and paratuberculosis as waterborne pathogens.
