  • 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.Cases have involved post-surgical sepsis, cannula-related sepsis, urinary tract infection a range of infections caused by MRSA and other pathogens, Clostridium difficile, Lyme disease and more general complaints of delayed or inadequate diagnosis or treatment.Other cases have involved sharps injury and other occupational illnesses including Legionella infection (Legionnaires Disease).
  • Expert was retained as the microbiology Expert Witness in the Powertrain case in which 90+ claimants alleged failure in the management of metalworking fluids as the cause of a range of respiratory symptoms including severe extrinsic allergic alveolitis.The case required review of all aspects of metalworking fluid management including its natural history and the nature of contamination with micro-organisms of environmental origin; technical assessment of microbial contamination including culture of metalworking fluids and a range of indirect markers; the use and control of biocide additives including biocide assay, biocide stability; the spectrum of activity of biocides, resistance mechanisms; the prevention and containment of metalworking fluid aerosols, and the burden of micro-organisms in air; PPE use; causative mechanisms.The case concluded with a meeting of Experts instructed by the Birmingham Country Court.
  • Expert has acted in a diversity of addition consulting activities including Crown Court and High Court cases, Public Inquiry, Planning applications and appeals, licenscing appeals and other regulatory processes including presentations to review panels at home and abroad as part of the application process for pharmaceutical licensing.
