I am a hydrologist interested in regional- to continental-scale groundwater systems, groundwater sustainability, groundwater lateral flows, groundwater-surface water interactions, and hyper-resolution hydrological modelling. I pursue my research interests by numerical modelling at the continental- to global-scale and learn from trends and anomalies from the past to predict the future.
