Stefania Cacovich and Laurent Bopp receive CNRS medals

Stefania Cacovich is a research scientist at the Institut Photovoltaïque d’Île-de-France. She earned her PhD in Materials Science from the University of Cambridge in 2018 and was a Marie Skłodowska-Curie Fellow at IPVF-CNRS from 2020 to 2022. Her research focuses on understanding the properties of emerging photovoltaic technologies through a multi-scale, multi-dimensional characterization approach. She addresses key challenges such as device stability and performance optimization, with particular emphasis on hybrid organic–inorganic materials, including halide perovskites. Stefania specializes in correlative imaging, integrating data from multiple techniques with artificial intelligence and physical modeling

Laurent Bopp is a climatologist and oceanographer at the Dynamic Meteorology Laboratory (LMD*). A graduate of the École Normale Supérieure and holder of degrees in biology and geology, he is a specialist in the ocean carbon cycle and its evolution in the face of climate change. His work focuses in particular on ocean acidification and the impacts of climate change on marine ecosystems, on all time and space scales. Author or co-author of over 200 scientific publications, he was lead author of the 5th and 6th IPCC reports. A professor at the ENS, he was awarded the Académie des Sciences' Prix des Sciences de la mer and elected to the Académie des Sciences in 2025.
