Professional interests:

• Role of shallow lakes in regional and global carbon cycling.
• The biotic and abiotic controls on the metabolic balance of prairie pothole shallow lakes.
• Decomposition of plants and algae in aquatic environments, and how this relates to carbon burial rate in lake sediments.
• Physical and chemical characteristics of shallow lakes and how they differ spatially and temporally in macrophyte and algal-dominated wetlands.
• The influence of fathead minnows and invertebrates on carbon cycling and burial in shallow lakes.
