Research Overview

My research focuses on the population and community ecology of freshwater fishes, often linking environmental stressors (e.g., climate change, 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.
