His research interests focus primarily on the regulation of gene expression through cell-cell communication (quorum sensing) in pathogenic bacteria and the development of novel anti-infective agents and bacterial attachment resistant polymers. He has published some 280 research papers, reviews and book chapters and patents. For his quorum sensing research he was awarded the Royal Pharmaceutical Society of Great Britain Conference Science Medal (1992), Pfizer prize in Pharmaceutical Sciences (1994) and the Society for General Microbiology Colworth Prize Lecture in 2007.
