Prof. Dr. Andrea I. Flossmann  is full professor at the University Clermont Auvergne (UCA) in Clermont-Ferrand (France), working in the Laboratoire de Météorologie Physique (LaMP),  a joint research unit with the CNRS  (INSU-UCA; UMR 6016). Currently, she is co-chairing the WMO/WWRP expert team on Weather Modification and took up in 2022 the responsability at the ANR (Agence Nationale de Recherche) of the PEPR TRACCS (Transform climate modelling for climate services). From 2004 to 2010 she was the director of the OPGC (Observatoire de Physique du Globe de Clermont-Ferrand) and has been involved in a number of EU projects (QUANTIFY, EUROTRAC, ACE…) and has coordinated FP6 EUSAAR and FP4 CIME and other national and international projects (BIOCLOUDS, BEAM,..). Her research activities focus on the study of the physico-chemical processes in clouds considering in particular the unknowns regarding the process of nucleation of liquid drops and ice crystals, their interaction and the consequences for precipitation formation. This research is based essentially on a modelling approach of clouds using three-dimensional meso-scale models with a bin resolved representation of warm and cold microphysics, as well as the particulate pollution in the hydrometeors and in clear air. She has published more than 120 research papers.
