Adjunct Faculty

Dr. Michael van Zyll de Jong is an applied ecologist that collaborates across disciplines to develop, synthesize, and communicate robust, relevant science that can inform inland fisheries management and policy development. His areas of concentration are in recreational fisheries assessment; river restoration and forestry impacts; policy development and decision making.
