My research interests connect aquatic ecology and quantitative ecology, with emphasis on impacts of human pressures on aquatic biota and ecosystem functioning. My research has been primarily focused on understanding the impacts of environmental perturbations on aquatic biota and ecosystem functioning, developing and using ecological indicators and assessing spatial priorities for management and conservation of fresh waters. My research spans various scales, from local to continental, and covers diverse organisms, from microbes to fish, to inform sustainable freshwater management and conservation strategies.
