Research Interests

Areas of research interest include transport and fate of zoonotic pathogens in watersheds and coastal ecosystems; effects of landscape change and climate variability on disease transmission; impacts of water scarcity and impaired quality on human and animal population health, and food safety.

Topics of research projects include:

  • Zoonotic infectious diseases
  • Waterborne infectious diseases
  • Food safety
  • Wildlife population health
  • Human public health
  • Epidemiology

Positions for graduate students are currently being considered. If interested please email me directly and include areas of research interest and current curriculum vitae.
