Research

My research interests are fairly broad, but revolve around biological interactions and community ecology. I’m interested in how local to global environmental change affects biological interactions, community diversity and ecosystem functions. I mostly focus on freshwater invertebrate populations and communities, but I also collaborate on works that deal with fish, terrestrial insects, and plant-insect interactions. My favorite projects take advantage of a natural ecosystem that is small and contained (allowing complete sampling of the organisms), widely distributed (allowing to test the generality of results over broad biogeographic gradients), and viewed by ecologists as a model system for testing ecological theory: the rainwater-filled leaves of Neotropical tank bromeliads and their aquatic food web. In recent-ongoing projects that make use of tank-bromeliads as model system, I aim at understanding how different scales of biological organisation, organisms, functional community structure, metacommunity, and their interactions, drive community re-assembly and multifunctional resilience in neotropical ecosystems, following drought events that range from the current norm to extreme events and predictions of IPCC.
