I am an environmental chemist with more than 25-year experience and a full professor in Environmental Biogeochemistry and Ecotoxicology, at the Department F.A. Forel for Environmental and Aquatic Sciences and the Institute for Environmental Sciences at the University of Geneva.  During the past 12 years I have served as a Director of the Department F.-A. Forel for Environmental and Aquatic Sciences, Vice-president and President of the School of Earth and Environmental Sciences at the University of Geneva. Currently, I am a member of the National Research Council of the Swiss National Science Foundation and represent the University of Geneva to the UNEP Global Mercury Partnership. I serve as Specialty Chief Editor Biogeochemical dynamics, Frontiers in Environmental Science.

My research is focused on development of novel concepts and tools for a better understanding of fundamental processes governing behavior and impacts of trace elements, nanoparticles and microplastics, their interactions with various biotic and abiotic constituents of aquatic systems. My research interests and portfolio include: (i) speciation and bioavailability of trace elements and nanoparticles in the aquatic environment; (ii) aquatic toxicology of inorganic contaminants, nanoparticles and microplastics; transcriptomics and metabolomics; (iii) community ecotoxicology and biodiversity in aquatic systems.

My teaching portfolio includes numerous classes in the area of environmental chemistry, ecotoxicology, environmental impact and water quality for the Bachelor students at the Section of Earth and Environmental Sciences, for Master students enrolled in the interdisciplinary Master of Environmental Science of the Institute for Environmental Sciences and Master in African studies of the Global Study Institute.
