Research interests: (1) Taxonomy, ecology and biogeography of water beetles and bugs in Mediterranean ecosystems; (2) Conservation of insects and aquatic ecosystems; (3) Ecology of saline rivers: composition and structure of macroinvertebrate community, primary production, secondary production, trophic interactions; and (4) Biomonitoring: biotic indicators of aquatic ecosystems. (5) Responses of organisms living in extreme ecosystems: marine rock pools, high mountain ponds, caves.
