John is a Chartered Chemist, Fellow of the Royal Chemical Society and Emeritus Professor of Chemistry. He graduated from the Pancyprian Gymnasium in 1954 and then studied at the University of London from where he received the BSc(Hons) in Chemistry in 1959 and the PhD degree in 1962.
Following postdoctoral studies at the Western University (Canada), he was appointed Senior Research Officer at the Cyprus Agricultural Research Institute. He joined the University of North London (formerly Northern/North London Polytechnic and subsequently London Metropolitan University) in 1966. He continued to teach there until his retirement in 2002, where he was also Research Director of the Faculty of Science, Computing and Engineering for several years.
His research interests centred on metal complexes and their applications in industry, medicine and synthesis. This has led to over 60 papers, books and patents. He has successfully supervised over 50 research students for both PhD and MPhil degrees.
Between 2005 and 2015, he was a Member of the Evaluation Committee of Private Universities in Cyprus and, since 2011 is a Trustee of the Radiomarathon(UK) Charity for children with special needs.
John devised the idea of the Cyprus Centre to address a need identified in the local community and became its first Director. Under his guidance, the Centre grew with many Cyprus and Greece-related activities undertaken. These included the organisation of conferences, exhibitions and the publication of books and research concerned with the Cypriot community in the UK.
John continues to guide and advise the Centre in his role as Patron.
