Personal profile

Research interests

Dr Shasha Han is an Assistant Professor in Physical Geography (Hydrology and Water Resources) in the School of Geography, Earth and Environmental Sciences (GEES) at the University of Birmingham (UoB). Her research mainly focuses on three interlinked themes: 1) Enhancing probabilistic flood forecasts, flood inundation mapping, and advancing the modelling of hydroclimatic extremes with reduced uncertainty; 2) Investigating changes in floods (e.g. magnitude, frequency, timing, and flashness) over time in the changing world and attributing the drivers (e.g. climate, land use, and pre-flood conditions) behind these changes; and 3) Advancing our theoretical understanding of hydrological processes considering both natural dynamics and the impacts from human activities.

Dr Han is passionate about hydroclimatic extremes, flood non-stationarity, hydrologic modelling, flood forecasting, climate change impacts, uncertainty analysis, urban hydrology, climate extremes and health, and data science.

Biography

Dr Shasha Han completed her PhD at McMaster University (Canada), where her work focused on probabilistic flood forecasting using advanced Bayesian techniques. She contributed to the development of the Canadian Adaptive Flood Forecasting and Early Warning System (CAFFEWS), and predicted future flood inundation by incorporating various sources of uncertainty and accounting for climate change impacts.  Before joining the University of Birmingham, Dr Han worked as a research associate at the University of Oxford (UK), where the focus was on investigating the impacts of urbanisation on river flooding and projecting river flows in the UK considering both urban expansion and climate change. At the University of Birmingham, her research has expanded into diverse areas, including flood non-stationarity, short-term flood prediction, long-term flood projection, integration of machine learning in hydrology, flood and drought alterations, surface water and groundwater interactions, as well as flooding and public health.
