Auburn, California

Steve has 18 years of experience conducting fisheries research in a diversity of aquatic systems from large floodplain rivers and estuaries in Texas and California to headwater streams in Costa Rica. His interests include river restoration strategies, predator-prey interactions, community dynamics, and population modeling.  He has conducted research on a wide range of species from gar and large river minnows to anadromous salmonids and sturgeon. Steve actively leads a team of biologists conducting numerous projects at CFS, ranging from field investigations and monitoring efforts to interdisciplinary modeling of complex adaptive management programs.
