Research Interests

  • Molecular studies of microbial and picoeukaryote communities in lakes and rivers.
  • Basic and applied studies of invasive species (zebra mussels).
  • Water resource management and environmental remote sensing.

Molecular studies of microbial and picoeukaryote communities in lakes and rivers. The biodiversity of freshwater microbial and picoeukaryotes is still understudied (compared with marine environments) with many more organisms to be discovered. We are using molecular approaches, as well as more traditional culturing and microscopic methodologies to elucidate the structure and function of community composition in Adirondack lakes, some of which have been impacted by acid rain or other pollutants.

Basic and applied studies of invasive species (Zebra Mussels and Asian Clams). Zebra mussels and Asian clams are invasive species that have significant economic and ecological impacts. We are carrying out basic studies on these invasives which include; development of molecular probes for their early detection and bioassays for gaining a better understanding of chemical and physical factors that influence or can predict their survival. We are carrying out applied studies that deal with management of these invasives once they have been introduced into freshwater bodies, as well as proactive monitoring/detection strategies to help prevent colonization.

Water resource management and environmental remote sensing. We are using a combination of traditional and advanced techniques to study human impacts on water resources. The approaches that we are utilizing include automated water chemistry profiling systems, side-scan sonar, satellite remote sensing, solar powered autonomous underwater vehicles (SAUV’s) and hydroacoutics, to name a few.
