Research Interests

  • Impacts of natural disturbances on tropical stream food webs
  • Drought impacts on food webs in the Flint River, Georgia

Research Projects

I am working with colleagues in Puerto Rico on the effects of urban growth, harvesting of freshwater shrimps and crabs, and intersections of road networks on river networks.  I am also collaborating with colleagues at the Joseph Jones Ecological research Center on the Flint River and Lake Seminole in southeast Georgia.
