Xavier Fettweis is a Belgian climatologist and professor at the University of Liège (ULiège)[1] whose research focuses on the surface mass balance and climate of the Greenland ice sheet[2] and the Antarctic ice sheets[3], on atmospheric circulation changes in the Arctic[4], and on regional climate projections for Belgium and western Europe.[5] In 2013 he received the European Geosciences Union's Arne Richter Award for Outstanding Young Scientists.[6] He is a member of the European Geosciences Union, the American Geophysical Union, and the Royal Academy of Science, Letters and Fine Arts of Belgium.[7]
Early life and education
[edit]Fettweis was born in Waremme, Belgium. He earned a master's degree in mathematics from the University of Liège in 2000, followed by a postgraduate diploma (DEA) in physics from the Université catholique de Louvain (UCLouvain) in 2001.[8] He completed a PhD in climatology at UCLouvain in August 2006, supervised by Jean-Pascal van Ypersele, with a thesis on climate modelling of the melting of the Greenland ice sheet using the MAR regional climate model.[1]
Career
[edit]Between 2001 and 2007, Fettweis held research positions at UCLouvain, including as a research fellow of the Fund for Scientific Research (Belgium) and as a research engineer in climatology. In September 2007 he returned to the University of Liège as an assistant in climatology, joining the Laboratory of Climatology led by Michel Erpicum.[9]
Since 2017 he is the head of Laboratory of Climatology at ULiège, succeeding Michel Erpicum.[10][11] He was appointed professor in 2025, and became vice-dean of research of the Faculty of Sciences in October 2025.[10]
Research
[edit]Fettweis leads the development of the MAR regional climate model[12] at the University of Liège and coordinates its application to the Greenland and Antarctic ice sheets, the Arctic climate, and climate projections for Belgium and western Europe.[13] His research has addressed ice-sheet surface[14] mass balance, atmospheric circulation[15], snow cover and flood risk[16], including the contribution of the Greenland ice sheet to past and projected sea-level rise.[17] He contributed to the IPCC's Fifth Assessment Report and has participated in international model intercomparison projects, including ISMIP6, for which he led the Greenland Surface Mass Balance Model Intercomparison Project (GrSMBMIP).[18]
Fettweis is also involved in the Katabata project with engineer Damien Ernst, which investigates katabatic winds in southern Greenland and their potential for wind-energy production.[19][20]
