Main research interests are in water microbiology with several areas of interest including:

Biological treatment of wastewater (activated sludge and maturations ponds) Treatment efficacy of alternative water sources – with respect to the removal of pathogens Improved rapid methods for the detection and enumeration of pathogens in water Microbial source tracking Communication of water science
