Short Bio

Louise is a Postdoctoral Fellow with Global Water Futures at the University of Saskatchewan in Canmore. Her research focuses on advancing the science and practice of ensemble hydrological forecasting. She has published her work in leading international journals, including Hydrology and Earth System Sciences, Geoscience Communication and Journal of Hydrometeorology. As an artist and scientist, Louise aims to further science engagement through the fusion of science and art. Louise is an active member of the HEPEX global community in hydrological ensemble prediction and a co-curator of the ConciliARTe science and art space.
