Research Interest

My main research areas are plant ecology and restoration ecology.  Nearly all of my works focus on restoration of sand dune communities, oak savannas, prairies and wetlands in the southern coastal areas of Lake Michigan.  Particularly, I am interested in investigating trajectories of restored vegetation in the prairies and wetlands of northwestern Indiana and northeastern Illinois.  Also, I am conducting a new project to study potential effects of atmospheric deposition of nitrogen on native plant communities in the Lake Michigan sand dunes.
