I am also Associate Scientist at the Institute for Sustainable Development and International Relations (IDDRI-SciencesPo, Paris). My current research relates to the effects of ocean acidification and warming on marine ecosystems and the services that they provide to society. I also investigate ocean-based solutions to mitigate and adapt to climate change. I led the launch of the Ocean Acidification International Coordination Centre at the International Atomic Energy Agency.I coedited the first book on ocean acidification (Oxford University Press) and contributed to several IPCC products (AR5, Special Report on 1.5°C of Warming, and the Special Report on the Ocean and Cryosphere).
