My current research activities are primarily focused on the use of molecular tools to address ecological questions in aquatic microbial ecology.  One project is the development of a comprehensive assay of microbial bioindicators for environmental monitoring and assessment.  A second addresses the use of molecular probes for detection and source tracking of waste inputs to streams.  I also have an ongoing interest in the role of microbes in arctic lake food webs.
