My profile

Biography

Academic and professional qualifications

PhD in Chemical Engineering from the University of Manchester.

Masters in Chemical Engineering with Industrial Experience from UMIST

Membership of professional associations

Associate Member of the Institution of Chemical Engineers

Research outputs

Member of the Advanced Materials and Surface Engineering Research Centre.

My research interests are in the area of non-thermal plasmas, in particular those used for materials production and environmental waste remediation.  I have experience in probing plasmas through a variety of infrared spectroscopic measurements, and correlating these with properties of the materials that have been produced by these plasmas.  Current research is directed towards water treatment by non-thermal plasma.
