Additional information

Industry experience

To increase both international research profile and contacts with British industry, undertook a secondment to Yorkshire Water Services (YWS) funded by the Royal Academy of Engineering and a research leave at the National Institute of Scientific and Technical Research in Tunisia

Member of the accreditation panel of the Institution of Chemical Engineering (IChemE) (2013-present).

Secondment to YWS gave an excellent experience with large scale ozonation systems and a real insight of the UK water sector needs and challenges
