Kat is an applied environmental microbiologist with over six years experience of investigating the microbial ecology of engineered systems. She earned her Ph.D.  in Civil and Structural Engineering from the University of Sheffield, where she investigated "The impact of hydraulic regime upon biofilms in drinking water distribution systems".

Now working as a Post-doctoral Research Associate, within the Pennine Water Group, Kat specialises in investigating the interactions between environmental microbial ecology, drinking water distribution systems and water quality.

Current Research

Kat's current research focusses upon the influence of disinfection concentration on biofilm physical (EPS and cells) and community structure (using molecular analysis), incorporating any impacts on water quality, particularly discolouration. This research is associated with the PODDS project.

Water Research && Technology, 2 (4), pp. 614-630. (Full Text)., Abstract: Drinking water quality deteriorates during transportation through drinking water distribution systems (DWDS). Microbial activity and ecology, particularly within biofilms that occur on the inner-pipe surface of DWDS, are emerging as important drivers in the degradation process. Yet, we have little...

(Full Text)., Abstract: High quality drinking water exits modern treatment works, yet water quality degradation such as discolouration continues to occur within drinking water distribution systems (DWDS). Discolouration is observed globally, suggesting a common process despite variations in source, treatment, disinfection...
