Research and Collaborators

We are driven to provide reliable, science-based information and solutions for the conservation and management of lentic and lotic biota and their ecosystems.  Our interests are diverse, including: food webs, native-nonnative fish interactions, fisheries management, reservoir limnology, bioenergetics, population dynamics, contaminants, quantitative models. Most of our projects benefit from close collaboration with managers and researchers from Colorado Division of Wildlife (CDOW), U.S.G.S., Bureau of Reclamation (BOR), National Park Service (NPS) and many others.
