I joined Keele University in October 2007 as a lecturer for Environmental Geoscience and am a member of the Research Institute for  Environmental Physics and Applied Mathematics EPSAM. Before coming to Keele I worked from 2005 at the Centre for Sustainable Water Management, Lancaster University and from 2000 – 2005 at the Geo-ecology Institute of the University of Potsdam/Germany.

Research and Scholarship

My research focuses on the experimental and model-based investigations of hydro-ecological and chemical processes at the groundwater-surface water interface. My work on riparian water balance and groundwater recharge in lowland areas is essential to understanding the influence of groundwater – surface water interactions for floodplain hydrological processes. I developed the IWAN (Integrated Water Balance and Nutrient Dynamics) model to successfully quantify the implications of groundwater – surface water influences on the riparian groundwater dynamics as well as on the riparian nitrate transport and retention. Applications of the IWAN model helped to identify and assess the importance of riparian nitrate attenuation on the lowland groundwater and surface water quality including the impact assessment of landuse change and managements scenarios in order to implement the requirements of the European Water Framework Directive (WFD).

My research also focuses on the investigation of groundwater – river connectivity. I developed an approach to delineate the temporally variable extend of riparian zones in dependency of the impact of groundwater controls onto the riparian water balance. I also aim to investigate the limits of applicability and uncertainties of coupled model approaches. In collaboration with the Environment Agency (EA) I developed a risk framework to assess the risk for pollution of groundwater dependent terrestrial ecosystems that are now used by the EA for implementing the WFD.
