My research efforts have been focused on two general areas of wetland ecology: (a) decay processes and the role of epiphytic organisms in these processes and (b) the impacts of various kinds of disturbance on wetland systems. Of these two foci, my primary emphasis involves microbial interactions associated with emergent plant decay, particularly within periphyton attached to plant material. Plant decay is one of the most important determinants of nutrient flux in wetlands are associated with plant decay; thus, the patterns of litter fall, organic matter decomposition, and nutrient uptake and release during decomposition are critical to understanding nutrient cycling and retention in wetlands. Our microbial work has demonstrated that positive interactions between epiphytic heterotrophs and autotrophs can influence decay rates, and that the metabolism of periphytic bacteria and fungi can be closely coupled to the photosynthetic rate of epiphytic algae.

My companion research focus is an outgrowth of the destruction and disturbance that have beset virtually all wetlands in the continental United States, e.g., 56% of all U.S. wetlands are already drained, filled or dredged. Of the remaining wetlands, two of the more subtle, but insidious, forms of disturbances involve sedimentation and invasive species. Past publications include the effects of sedimentation on wetland seedbanks, emergent plant decay, and wetland benthic macroinvertebrates. With respect to invasives, we have focused on the influence of purple loosestrife on wetland seedbanks and wetland plant competition.
