He is a member of the EPSRC Peer Review College, a referee for Research Council and Charity research grant proposals, a member of the Editorial Board for Rapid Communications in Mass Spectrometry and a reviewer for all other leading mass spectrometry, chromatography and chemistry journals; has also been called as an expert witness; MS consultant; is a freelance Team Development trainer and involved in the organisation and implementation of the School of Chemistry key skills programmes.

To date, John has 80+ refereed publications; with an ‘h-index’ of 28 and over the years has been involved in the analysis of organometallics, oligonucleotides, bio-organic chemistry, natural products, proteins, supramolecular chemistry, target synthesis, combinatorial chemistry pharmaceutical and oilfield chemistries. External academic collaborations include early studies of fullerene MS with the Sussex group. This range of chemistries has led to publications in over 30 different journals.

During his time at Southampton, he has developed his own research group ( and worked on MS problems that span the spectrum of chemical sciences, with other research groups both within and outside Southampton. External academic collaborators include AstraZeneca, BP, GSK, LGC, Pfizer, Waters and early studies of fullerenes with the Sussex group.
