ºÚÁϳԹÏ

Summary

I am Professor of Environmental Technology and research lead for the School of Civil Engineering and Surveying.

I am Director of the Environmental Technology Field Station, a unique facility based at Petersfield wastewater treatment works.  This facility has laboratories and test beds which allow us to work on pilot scale treatment systems using real sewage.  It is the base for a major collaboration with Southern Water to create an Innovation Hub for addressing the problems facing small sewage treatment sites.  The site also hosts pilot plants with other industrial collaborators, such as WPL Ltd.

My work is mainly concerned with water quality improvements in wastewater and sustainable drainage (SuDS).  Currently we are looking at ways to remove phosphorous from sewage that avoids the need for chemical dosing and large scale infrastructure in collaboration with Southern Water.  We have recently completed projects looking at pharmaceuticals in sewage (Astra Zeneca), the fate pollutants in SuDS and also a NERC Green Infrastructure Innovation Project looking at ways in which developers can account for the multiple benefits of SuDS.

Overall the aim of this work is to develop low impact solutions to real world environmental problems.

Biography

I graduated from Kingston Polytechnic in 1988, with a BSc (Hons) degree in Resources Science.  I then came to ºÚÁϳԹÏPolytechnic to undertake a PhD examining nitrogen cycling and pathogen removal in constructed wetlands in the UK and Egypt, which was awarded in 1993 by the newly established ºÚÁϳԹÏ.  I then stayed at ºÚÁϳԹÏto do a post-doc examining the application of constructed wetlands to industrial wastewater and worked on various projects in Egypt, South America and Europe.

I have stayed at the ºÚÁÏ³Ô¹Ï ever since, becoming Lecturer, Senior Lecturer and Principal Lecturer, before being promoted to Reader in 2015 and Professor in 2017.

During my time at ºÚÁϳԹÏI have led many projects in collaboration with industry, supported by funding from a range of sources such as Innovate UK and (as was) RCUK.  My work on constructed wetlands has extended to monitoring and modelling vegetated sustainable drainage systems (SuDS), starting with the A34 Newbury Bypass (Mott MacDonald) and then to SuDS in housing developments (Mayer Brown/InnovateUK and NERC).  I have also worked on many wastewater treatment projects including the characterisation of fatberg deposits (WRc/EPSRC) and assessing the fate of pharmaceuticals (Astra Zeneca/EPSRC).

Research interests

My research mainly focuses on water quality in wastewater treatment and sustainable drainage, although I have also worked on a number of projects concerned with sustainability appraisal.  My main focus has been on low impact technologies, particularly those based on natural processes and wetland plants. Ongoing projects include:

• Wastewater treatment technologies for small sites
• Use of constructed wetlands for wastewater treatment and runoff management
• Fate of microplastics in wastewater treatment and drainage systems
• Remediation of polluted sediments
• Removal of pesticides from runoff in Thailand

PhD Research Supervision

I have supervise 24 PhD students to completion and welcome applications from potential research students in the fields of wastewater treatment and urban runoff management.

Media availability

I am happy to take calls and emails from media on my research and I am aware of the need for timely responses. I like to restrict comment to projects I have undertaken or where I have specific expertise.

Interested journalists can also contact the University's Media and Communications team for support and advice on all media engagement, including out of hours.
