Background

Background

I’m a self-motivated environmental engineer with over a decade’s worth of work experience in field and laboratory positions. I’m passionate about research, especially when it comes to biological treatment systems and how they can be used to achieve the UN’s Sustainable Development Goals.

I’ve always had an interest in the interactions between what we do as humans and the environment, particularly how we can negatively affect it and our health. I’ve gradually moved from an ecological point of view at the landscape scale to the microbial ecology level via biogas optimisation. The science and technologies we continue to use and champion for wastewater and water treatment are resource hungry (i.e., energy, carbon, nitrogen) and emit huge amounts of greenhouse gases through the process. I think the use of biological systems, in conjunction with their chemical parameters, will provide solutions to many world problems; namely, wastewater energy use and safe water.

I enjoy contributing to a wide range of teaching venues form traditional classrooms to laboratory and field settings to both formal and informal seminars and workshops. Working with students continually brings a fresh viewpoint to what I do and keeps me on my toes.

Before joining the University, my worked encompassed ecology, waste, and river pollution for TNEI and Gardiner and Theobald consultancies, Durham Wildlife Trust and the Environment Agency. I maintain close contact with my previous employers and work colleagues, while developing new networks within the UK water industry as well as globally.

Current Work

Currently, I co-lead a collaborative project with partners in Malaysia to improve community health through sustainable, decentralised wastewater treatment of antibiotic resistant bacteria. Inadequate small-scale wastewater treatment, such as septic tanks used by many rural Malaysians, has led to suburban and rural water environments in SE Asia being generally poor. Our research is contributing to reducing the spread of AMR in waterbodies in Malaysia by guiding wastewater management approaches. In academic terms, the work will not only produce UK-Malaysia collaborative manuscripts based on yearlong and shorter intensive sampling regimes but also on multidrug resistance. Our work in discovering these results has huge potential to save the lives of millions of people in the developed and developing world.

 

I’m working on a project comparing gut microbial ecology of undernourished patients and their levels of antibiotic resistant bacteria. In addition, I’m working with colleagues at York University on the impact of irrigating crops with wastewater containing different levels of AMR bacteria has on soil biota.
