I am a freshwater community ecologist interested in the processes driving (meta)community assembly and ecosystem functioning in river networks. My research focuses on how connectivity (dispersal) and flow disturbance (droughts and floods) affect river community spatiotemporal dynamics within and among river networks. From the intermittent rivers of the Mediterranean to the groundwater-fed English chalk streams and the dense boreal river networks, I explored the effect of extreme hydrologic events and seasonal flow intermittency on community assemblies across climates. Future research includes exploring community synchrony and temporal changes in metacommunities, the contribution of dispersal to community assembly, and the links between metacommunities and ecosystem functioning at the river network scale.
