Trained in the UK NHS and University Medical Schools, he specializes in microbiology, infection and infection prevention, and hygiene, with over 35 years post-qualification experience. This includes a 7-year attachment as microbiologist to the academic Department of Surgery of the Royal Postgraduate Medical School where I developed research interests in device-related and surgical infection, antibiotic prophylaxis, and in particular hepato-pancreaticobiliary tract infections.

Expert has additional research interests in hygiene management, infection prevention and control, and the wider aspects of occupational and environmental hygiene management. Expert has a wide academic overview and involvement in teaching and training of healthcare-related and occupational infection prevention and control, healthcare hygiene, sharps and bio-safety, bio-hazardous waste management and waste-related occupational safety. This creates a possibly unique role combining the skills of an infection prevention specialist and waste manager, academic, researcher, teacher and trainer, with many years’ experience in the healthcare, regulatory, academic, and commercial sectors.

In 2010, Expert was invited to review and subsequently to brief the Government of the Isle of Man concerning the arrangements for island-wide clinical waste management. Current waste management arrangements were examined in depth, including a comprehensive waste audit at the Island's main hospital. This was extended to an examination of hygiene and health and safety matters, logistics, cost appraisal and compliance with the EU and UK legislative frameworks to refine existing waste management arrangements, promote best practice, and reduce the volumes of waste processed in a dedicated clinical waste incinerator that suffered high dioxin emissions due to its discontinuous operation profile.

Peripherally, this project involved support of a University of London postgraduate student in the conduct of waste and environmental auditing.

Expert has reported on many cases of medical malpractice, each involving some aspect of microbiology.

Cases have been received from private clients and instructing solicitors, and from the Healthcare Commission for whom Expert was appointed as an adviser in microbiology from 2006 to its dissolution in 2009.
