Introduction
I'm an associate professor (i.e. maître de conférences in French) at University of Reunion Island, a French Island in the South West Indian Ocean. I share my time between teaching (undergrads and graduate students) and research. My research fields are related to coral reef ecology, including hard corals population dynamics, recruitment, and demographic processes as well as interactions among corals, algae and herbivores or disturbances in reef environments.

Article
Corals and coral-associated species are highly vulnerable to the emerging effects of global climate change. The widespread degradation of coral reefs, which will be accelerated by climate change, jeopardizes the goods and services that tropical nations derive from reef ecosystems. However, climate change impacts to reef social–ecological systems ca...
