Staff Profile

Background

From a strong background in classical environmental engineering, I have become a specialist in the microbial ecology of biological wastewater treatment systems, infrastructure essential to society on a global scale. Through my academic research and interactions with industry, I have developed a unique combination of skills and gained experience and expertise that lies at the interface between environmental engineering, theoretical ecology, microbiology and virology. My ambition is to utilise this knowledge to move towards a more sustainable future for the water and wastewater industry, thus society as a whole, by developing methods, theory and tools for the control and management of engineered microbial communities. 

My principle research interests lie in the field of biological wastewater treatment and the use of ecological approaches to better understand the microbial communities that drive these globally important processes. I am currently working as part of a multidisciplinary team investigating the rules that determine the growth and dynamics of complex biological communities in such systems, incorporating biological, chemical, physical and hydrodynamic interactions (Website). This research builds on previous work I have undertaken looking into the role of environmental and stochastic effects on the composition of microbial communities, again in biological treatment systems. Alongside both projects, as part of my doctorate, I explored the impact of bacteriophages on such systems, both in terms of their role in community composition and structure and on function (plant performance) and functional stability. It is this exciting and potentially important arena that I see my future research. Unearthing the role viruses play in regulating the microbial communities and functional performance of engineered systems could be crucial in endeavours to better understand, manage and optimise these systems, which are currently facing unprecedented demands imposed by population growth, climate change mitigation and increasingly strict environmental regulation. Realising their potential to control problematic bacteria in engineered systems also offers an exciting research opportunity.
