My research is directed at applying ecological principles to conservation and management of aquatic ecosystems. I am interested in trophic interactions, reservoir ecology, effects of nonnative fishes, fisheries management, limnology, bioenergetics, contaminants, population dynamics, computer models. My current work is focusing on anthropogenic influences on aquatic ecosystems such as climate, invasive species, reservoir operations, sport fishery harvest regulation, fish stocking, and contaminants. I enjoy applying a wide variety of techniques and approaches including field sampling, modeling, field experiments, classical fisheries biology analytical techniques, stable isotope analysis, and otolith microchemistry. I am building bridges (excuse the pun) between aquatic ecology and environmental management with water researchers in CSU's engineering departments. Most of my projects benefit from close collaboration with managers and researchers from Colorado Division of Wildlife, U.S. Bureau of Reclamation, U.S. Fish and Wildlife Service, and folks in several other state and federal agencies.
I have become increasingly concerned about the issue of illegal stocking and developed a website devoted to curbing the practice: Illegal Stocking Website.
My teaching responsibilities include our senior-level Fishery Science course FW401 which stresses the quantitative aspects of fishery biology and fishery management. This course includes a laboratory section for hands-on experience with concepts discussed in lecture; labs stress computer applications for fishery analysis. I also teach Ichthyology FW300 and FW301 which cover fish anatomy and physiology, evolution and systematics, ecology, genetics, zoogeography, and conservation biology. I regularly co-teach graduate seminars and give numerous guest lectures in undergraduate and graduate courses. I draw heavily on my research experience to provide contemporary, interesting and illustrative examples for all of my courses.
