Research Interests: 

My research focuses on the population and community ecology of freshwater fishes, often linking environmental stressors (e.g., large reservoirs, groundwater pumping, wildfire) to freshwater fish population and assemblage dynamics across a variety of aquatic ecosystems. This research bridges the gap between basic and applied fisheries ecology, integrating quantitative ecological analyses, spatial statistical methods, landscape ecology and conservation biology to address conservation and management issues. Recent projects have focused on evaluating spatial ecological processes as predictors of steelhead spawning distribution, vulnerability analysis of bull trout habitat and populations to wildfire and climate change, designing practical applications for spatial stream network models, and developing multi-state occupancy estimation methods for lotic systems.
