My teaching role is in the civil engineering suite of programs where I mainly teach soil mechanics, geotechnics and project modules on HNC and undergraduate programs along with environmental subjects on the Water, Energy and the Environment MSc program.
My PhD research was a collaboration between industrial partners (Hydro International Plc and United Utilities Plc) focussed on assessment and improvement of a tertiary wastewater filtration process. This project involved combining the findings from laboratory (university based) and practical based fieldwork (United Utilities field site) into a numerical dataset from which I developed a predictive mathematical model of efficiency for the process. The research led to a number of publications and speaking at a number of conferences and this research is ongoing with several new PhD students continuing this research line where I am actively involved in supervising this research.
