Areas of Interest/Expertise

My primary research covers all aspects of cutthroat trout conservation and management but has been focused recently on developing the taxonomy of southern Rocky Mountain subspecies. In addition, I maintain ongoing projects dealing with hydroacoustics, mountain whitefish, northern pike, and tiger trout.

Current or Recent Research Projects

• Cutthroat trout taxonomy – molecular and meristic investigations
• Fitness in small populations - consequences of genetic bottlenecks
• Adaptive capacity in cutthroat trout
• Population viability
• Mechanical removal of competing non-native salmonids
• Cutthroat trout movement and habitat use in small streams
• Methods to improve success of salmonid wild spawn operations
• Hydroacoustic methods to estimate trout population and individual size
• Software development
• Temperature monitoring
• Fishery data analysis 
• Telemetry 
• Hydroacoustic data
• Bootstrapping
