Current research interests focus on the quantification of surface reacting solute transport in groundwaters and the quantification of inorganic nanoparticle movement in groundwaters. This work involves laboratory and field experimentation, and modelling. Within the Water Sciences group, there are extensive facilities for this type of research, including an on-campus research borehole array.
Most recent research projects have centred on: virus movement in groundwaters (NERC, European Union, and Environment Agency funding); nanoparticle movement in groundwaters (NERC); and applications of biogeochemistry in nuclear waste disposal (EPSRC). PhD and PDRA research has recently included work on: characterizing surface properties of rocks; examining particle/virus interactions; quantifying correlations between hydraulic properties, geochemical properties, and lithofacies; quantifying ion exchange reactions; and developing new methods for borehole logging interpretations.
