Profile

 I am an environmental microbiologist with specific interests in freshwater pollution and wastewater treatment. My current research is part of MicroAqua, a large European project which has been designed and is being implemented according to the guidelines of the European Water Framework Directive (2000/60/EC). My research aims to characterise cyanophages which have potential application for the control of cyanobacteria which form toxic blooms in freshwater.

I spent time during my Ph.D evaluating the complicated interactions between chemical and microbiological factors of wastewater treatment, and am particularly interested in the application of genetic profiling techniques, such as denaturing gradient gel electrophoresis (DGGE), for the assessment of community composition change over time, and in response to environmental variables. The combination of data obtained by molecular techniques, with multivariate statistical analysis, is something which has powerful implications for the study of complex microbial communities such as those found in activated sludge. This is another aspect of my work, based on studies performed during my Ph.D. The research group in the School of Civil Engineering and Surveying, where this work was based, has plans to extend these methods of study into the investigation of fats, oils and grease accumulation in wastewater treatment facilities.

I have also been involved with work characterising the metabolic activity of sulphur and iron oxidising bacterial populations associated with the Mary Rose.

Research Interests

Genetic diversity of freshwater cyanobacteria and the cyanophages which infect them, the possibilities for subsequent application to water pollution control.

Wastewater treatment by small systems, specifically:

• Microbial communities associated with biological nutrient removal (BNR), enhanced biological phosphorus removal (EBPR) and system failure.
• Methods for multivariate statistical analysis of wastewater treatment systems

Microbial communities associated with the breakdown of fats, oils and greases in sewerage systems.

Microbial ecology associated with the Mary Rose.
