I have been studying the ecology of coastal communities (coral reefs, rocky shores, deep reefs and seagrass) for the past 30 years in many biogeographic regions (Mediterranean, Red Sea, Pacific, Atlantic and Caribbean coasts). My lab currently runs the national monitoring program on rocky shore biodiversity, and investigates the ecology and biodiversity of Mediterranean coastal communities, and the effects of bioinvasions, climate change (warming, acidification, sea level rise and extreme events) and marine protected areas on these communities and their functions.
