Gabriel (born 1966), also known as Gabriel Opoku Adusei is a Ghanaian British Medical Device Technology Expert with backgrounds that stem from Pharmaceutical and Biomaterial Sciences. Gabriel has contributed to several innovative projects in bringing new technologies to the marketplace and many developments in the medical device industry with a significant number of publications, many of which aim at improving Quality Management Systems and Regulatory Practices.[1]

Early life

Gabriel Adusei was born in Kumasi, Ghana; and immigrated to the UK in 1990. He enrolled on an undergraduate Biomedical Science course at the University of East London at Stratford but dropped out as he could not financially sustain his education. He enrolled in Pharmaceutical Science at the University of Greenwich and went on to complete a postgraduate course of MSc in Pharmaceutical Science and Industrial Studies which he earned distinction with his final project work in Quality Assurance and Regulatory Affairs in the Medical Device industry.

He has worked in the dental restorative materials production environment as a Manufacturing Chemist. For his PhD research at King's College - London, he develops novel polyacid-modified restorative dental composite, commonly known as “Compomer” based on vinyl phosphonic acid and its derivatives phosphonated Bis-GMA (bisphenol A-glycidyl methacrylate)[2] and resin-modified glass-ionomer cement based on polyvinyl phosphonic acid-modified monomers. The novel synthesised monomers were aimed at improving the adhesive function the dental restorative materials to the tooth structure as well as having the improved features such as fluoride-releasing for the remineralisation of teeth as well as acting as an oral anti-bacterial agent and providing durable mechanical properties. These types of dental restorative materials are widely used in dentistry.

Personal life

Gabriel got married to Esther Hagan-Brown who he met at the Guy’s King’s and St Thomas Dental Institute of King’s College, London in the year 2000 where she was a Dental Laboratory Technician (dental technologist).

Career

In 2002 He joined the School of Dentistry of the Cardiff University School of Medicine (formerly known as the University of Wales, College of Medicine) at the University Hospital of Wales at Heath Park in Cardiff, as a Postdoctoral Research Fellow to develop a sensor used with bladder urinary catheter to detect the early stages in the development of crystalline Proteus mirabilis biofilm on indwelling urinary bladder catheter that leads to encrustation and eventual blockage of the lumen.[3]

The sensors were prepared by dissolving cellulose acetate in acetone and adding a mixture of Bromothymol blue (also known as bromothymol sulfone phthalein and BTB), a pH indicator and sulfuric acid.

After postdoctoral research, Gabriel was employed by the Dental School as a lecturer in 2004, teaching Biomaterial Science of dental and orthopaedic restoratives as part of his research interest in medical devices. He was an active research member of the Wound Care and Endodontic Research groups at the School of Dentistry of Cardiff University. Gabriel is also known for his keynote presentations on the subject of Biomaterials and Medical Devices at international conferences.[4][5][6] He has worked for BSI and Intertek as a Technical Reviewer, Project Manager and an Auditor. Gabriel became the Course Director at Cranfield University for Medical Technology Regulatory Affairs, a postgraduate course developed as a collaboration between “The Organisation for Professionals in Regulatory Affairs” (TOPRA) and the university to offer a formal academic recognition on the career development pathway in the industry. He is currently a consultant in the medical technology industry and has served the likes of Philips Healthcare and NSF International.

He serves as one of the research grant reviewers of EPSRC. Gabriel works as a consultant at Triune Technologies Limited, UK, serving the Medtech industry and helping in the shaping of many aspects of regulatory practice through his publications and other significant contributions including conference presentations and lecturing on courses. He is an advocate of technologies referred to Remote Patient Health Management utilizing Connected Health and Medical Devices with Software Apps the employ Artificial Intelligence (AI) or Machine Learning in the Cloud computing environment to deliver healthcare services. Gabriel was also the Information Security Officer at Cydar Medical at Barrington, Cambridge with roles involving Information Security Management System, Data Security and Protection as well as the use of information technology in medical devices. One of his projects was themed as “Kits for Kids in Need”[7] which successfully helped local schools in Ghana with redundant sports kits donated by Cambridgeshire and Huntingdonshire Football Associations.[8]
