Throughout my education and career, I have always been fascinated by the diversity and metabolic capabilities of microbes that are critical to sustaining many vital natural processes on Earth, some of which can be enhanced or managed for the benefit of humanity. The services microorganisms can provide are especially pertinent given the increasing anthropogenic pressures on the Earth system that threaten both environmental and human well-being. These pressures include chemical and nutrient pollution that affects soils, sediments and the water environment.
My research has therefore focussed on understanding relationships between microorganisms and the processes that they mediate, using a combination of quantitative molecular tools and modelling in natural and engineered environments. Such knowledge is critical for the prediction, management and mitigation of pollution in the environment, and naturally necessitates an interdisciplinary approach. I have largely applied this approach to engineered treatment systems and to regulatory hazard classification/risk assessments for manufactured chemicals.
I have extensive experience and expertise at the interface of environmental engineering, microbiology, and environmental risk assessment.
After gaining a first degree in microbiology, I worked for two years as a process engineer with a subsidiary of Yorkshire Water specialising in industrial wastewater treatment, including high-rate anaerobic biological systems. I first moved to Newcastle to complete an MSc in Industrial Biotechnology.
I then joined the School of Civil Engineering & Geosciences as a postdoctoral member of staff in 2000 after completing my PhD; one of the first in the UK to take advantage of the newly emerging quantitative molecular tools to gain an improved understanding of biological wastewater treatment. I was subsequently awarded an EPSRC Research Associate Industrial Secondment to Brixham Environmental Laboratory, AstraZeneca where I was based during 2002, which started my interest in the role of biodegradation in the fate, ecotoxicology and regulation of chemicals. On returning to the School in 2003 I became a School Research Fellow and was awarded an RCUK Academic Fellowship in 2007.
More recently, I won an EPSRC Challenging Engineering award in 2011, which officially makes me a Challenging Engineer, although I think this sends out the wrong message; I prefer to think that my chosen engineering subject is challenging and not me!
