Stéphanie Ponsar

Biography

Stéphanie Ponsar is a marine system modeller whose research centers on understanding how coastal ecosystems respond to climate change and chemical pollution. She applies a range of methods, including numerical modelling, data assimilation, and machine learning. She has contributed to the development of sediment transport and pollutant transport modules in the COHERENS model.
