Anne-Sophie LIBERT



Anne-Sophie Libert is a Professor at the Department of Mathematics. She is also director of the Namur Institute for Complex Systems (naXys) since 2017 and board member of the Technological Platform for High Performance Computing (PTCI) since 2015.

As an FNRS (Belgian National Fund for Scientific Research) Research Fellow, she got her PhD thesis in applied mathematics at UNamur in 2007. After a postdoctoral stay at the University of Thessaloniki in 2008, she obtained a 4-year F.R.S.-FNRS Postdoctoral Research Fellowship at UNamur, during which she spent a one-year research stay at the University of Lille (Institut de Mécanique Céleste et de Calcul des Ephémérides, 2012). In 2013, she was consecutively researcher for the 'Dysco' IAP and the F.R.S.-FNRS 'ExtraOrDynHa' PDR at naXys, showing her interest for a multidisciplinary research in applied mathematics. She became an Assistant Professor at UNamur in 2014.

Her main research topic is the formation and evolution of extrasolar systems, with a particular focus on the question of life in these systems (exobiology).
