Kraft studies ecosystem interactions that influence the management of freshwater fish populations in lakes and rivers -- with an emphasis on Adirondack ecosystems. His research efforts involve large-scale and small-scale experimental manipulations, as well as taking advantage of natural experiments that can help identify key ecosystem processes.
