Dr. Anita Cadoux is an experienced volcanologist whose research can be described as making volcanic rocks talk. To that end, she developed expertise in fieldwork, and in state-of-the-art petrological and geochemical methods. She first investigated the origin and evolution of magmas and the spatio-temporal distribution of volcanism in Italian volcanic provinces and the Trans-Mexican volcanic belt.
About 8 years ago, Dr. Cadoux initiated a new line of research concerning the abundance and behaviour of halogens (notably bromine) in magmas and the atmospheric impact of volcanic eruptions, in particular through their emissions of chlorine and bromine, whose role in stratospheric chemistry had been hitherto largely neglected. Her first results, obtained in collaboration with atmospheric chemist Slimane Bekki (an IPCC member), showed for the first time that large explosive eruptions, through their halogenated gas emissions, can bring about global-scale stratospheric ozone depletion, in turn, representing a significant climate forcing factor (https://www.nature.com/articles/srep12243).
Dr. Cadoux is Associate Editor of a special collection ("Halogens in Planetary Systems") in the international journal 'American Mineralogist' (2019-2022). She currently holds an Associate position at Harvard University in the framework of her collaboration with Dr. David Wilmouth and Dr. Freja Oesterstroem about the impact of volcanogenic halogens on the stratospheric ozone and climate.
