Dr Vasileios Christelis

Groundwater and hydrological modeller
BGS Keyworth

Dr Vasileios Christelis is an environmental engineer with an expertise in groundwater modelling and water resources management. His current research interests include variable-density flow in coastal aquifers and salars, flow and heat transport modelling for geothermal applications, groundwater drought, surrogate modelling for optimization and sensitivity/uncertainty analysis. Within his BGS role, Vasileios has contributed to groundwater/hydrological modelling projects primarily in the UK environment, as well as in Africa, the Philippines, and South America.
