Professional Activities and Interests

    My research program that covers environmental microbiology, including public health, microbial pathogens in the environment, waste management, the impact of releasing genetically modified organisms into the environment, and determining sources of fecal pollution in water.

Courses

Course Number Course Name
ENSCS (CEE, BIOL) 4164 Environmental Microbiology

Current Projects

    Over the past twelve years, I have been involved in the development of microbial source tracking methods, and have deployed these methods to determine sources of fecal pollution in 40+ projects in Virginia and 14 in other states. My research program on source tracking has been supported by competitive awards from USDA-NRI, EPA, NOAA, and USGS.

Recent Honors

  • Distinguished Service Award, USDA, for service to the National Biological Impact Assessment Program (NBIAP).
  • Outstanding Service Award, U.S. EPA, for service on the Biotechnology Science Advisory Committee (BSAC).
  • Distinguished Service Award, American Society for Microbiology, for service on Editorial Board of Applied and Environmental Microbiology.
  • Distinguished Service Award, Maryland Biotechnology Institute, University of Maryland, for service in the short course: Dealing with Field Test Regulations and Public Acceptance of Genetic Engineering.
  • Outstanding Service Award, National Onsite Wastewater Recycling Association, for service on the Board of Directors.
