My research sets out to improve our understanding of freshwater ecosystems and how these are responding to global change. Doing so, I study contemporary changes in landform types, the distribution of species functional adaptations to life in water, and the interlinkage between landscape changes and ecosystem functioning. My research combines observational field data, museum collections, public data resources, and modelling to describe the reciprocity between biodiversity and freshwater in the landscape. In addition, I work with method development within biodiversity monitoring, including remote sensing, automated image classification, and environmental DNA based monitoring.
