Professor Piani studied oceanography and atmospheric sciences at the University of Washington, Seattle, funded by a comprehensive four-year Fulbright scholarship. He obtained his PhD in 2000 with a thesis on 3D modelling of atmospheric waves triggered by very intense thunderstorms. He went on to work as a post-doctoral researcher on ozone, mid-atmospheric dynamics and climate change at the University of Oxford in the Atmospheric, Oceanic and Planetary Physics department. In 2006 he moved to The International Center for Theoretical Physics (ICTP) in Trieste, Italy, where he was awarded funds from the European Union for research in hydrological modelling. Piani remained at ICTP as a visiting scientist until joining The American University of Paris in 2012. His current research interests are bias-correction of climate model output, and climate driven evolution.

News

Upcoming book chapter: Book title “Climate Extremes and their implications for impact modelling in different sectors” published by Elsevier. The book is supposed to describe challenges and opportunities for addressing the impacts of climate extremes across various sectors, particularly in impact modelling studies. Further, the book will also provide an overview and link between model-based and observations-based analysis.
