Professional qualifications

Chartered Engineer

Most recent position:

Dates: 1989 - June 2009
Employer: Medical Engineering  - Manchester Royal Infirmary
Position: Principal Clinical Scientist
Salary: e-mail for details

Principal Clinical Scientist, working for the Central Manchester University Hospitals NHS Foundation Trust, my main roles include:

The Medical Engineering Department is responsible for maintaining and managing the medical equipment for the Manchester Royal Infirmary, Manchester Royal Eye Hospital, St Mary’s Hospital, Manchester Dental Hospital, Royal Manchester Children’s Hospital and Booth Hall Children’s Hospital.

Duties and Responsibilities:

Over 40% of my time was spent focussed on medical research. The recent focus of this research has been the identification and classification of patterns in complex physiological data. This has also included nonlinear analysis, statistical analysis, modelling of oesophageal motility and the use of neural networks and AI methods to classify the data from GI measurements. Part of my role included the giving advice and assisting in data analysis from all areas of medicine as requested. My work has included the development of software and instrumentation systems for the analysis for gastroenterology motility data. This work was carried out in conjunction with the GI Unit and the University Department of Surgery. This involved the development of a system to combine oesophageal manometry and digital video fluoroscopy, a system used in regular clinical practice. My role includes the identification and development of of new areas of research. I developed a wide range of contacts and contribute to the field of gastrointestinal (GI) measurements. I regularly present papers regarding my work at conferences and was a visiting lecturer on medical devices for the Association of GI Physiologists training courses and supervise medical research projects. I am an Honorary Research Fellow of the University of Manchester.

A further 40% of my time was spent in the management and development of IT facilities within the Medical Engineering and Maintenance Group. My role involves identifying IT requirements and then designing and developing full software solutions, this includes the administration of a network of 30 PCs. I have developed a comprehensive medical equipment information management system (MIMS) based on the MS Access database system. This included equipment inventory, equipment history, work planning, staff management, stock control, ordering, safety and hazard control etc. My most recent projects have involved the development of a hand held PC based system to manage offsite maintenance jobs and the development of a staff management modules including staff competency assessment and management. 

Any remaining time was taken up with contract and equipment management. Medical Engineering and Maintenance was financed from service level agreements both internal and external to the Trust. Unlike many Medical Engineering Departments for each item of equipment was identified on a service level agreement and a charge for a given level of cover is made which can be compared directly with that of the manufacturer or supplier.

I also contributed to the overall management of the Medical Engineering Department for example by co-authoring the Trusts Medical Device User Manual which includes all the Trusts polices regarding Medical Devices and authoring the Departments Staff Manual.

Principle Interests

Research

My interests include developing and carrying out research in Medical Engineering and Clinical Physiology. I try to keep actively involved in a number of research areas, these include:

This work includes both independent and collaborative research on a range of subjects ranging from analysis of complex time series data to ergonomic assessment of new medical devices. A list of recent presentations and publications can be found on my CV and examples of my work can be downloaded from the Downloads page. My other interests include the active mentorship of a wide range of clinical staff.

Medical Engineering

As part of my managerial roles I am also interested in all aspects of Medical Equipment Management. My main roles relating to medical engineering include:

I have amassed a wealth of experience, with over 22 years in the UK's NHS, much of which has been as a senior member of staff with a large Medical Engineering Department in one of the Uk's foremost teaching hospital Trusts. The challenges are always changing and varied as both the techniques and NHS are continuously developing

Professional activities

I am a Chartered Engineer and member of the Institute of Engineering Technology (IET). I have a wide knowledge of medical equipment, computers in medicine and their role in data modelling and analysis. Continuing to develop my skills and knowledge is a constant challenge. I have played an active role with the Association of GI Physiologists and my experience has been rich and rewarding and I am looking forward to continue to develop my career in medical research. My management interests have also included the proposal to state register staff who carry out maintenance, repair and servicing as 'Clinical Technologists'. If you are interested in 'Clinical Technologist' registration you the following reports made for the IET and IEE (follow IET and IEE links ) and for the latest open meeting with the NHS Chief Scientific Officer regarding this subject (follow this Link).

IT Skills

My first experience of programming was using punch cards in Fortran 77 on what were considered large Primus Computers and coding of 4-bit microprocessors. Since this time computing has come a long way. Throughout my career most of my positions have involved extensive use of computers and programming. I have developed this area of expertise and continuously look to learn and make use of the latest software technologies. I also have considerable experience with PC based software and instrumentation including significant skills in application development. I enjoy the challenge of learning software languages or software tools.

My skills and experience include, to mention a few: Visual Basic - I have extensive skills in software development using Visual Basic. A substantive part of my PhD research has been the development of software, which enables recording of synchronised digital video and physiological data. MS Access - I have developed major database systems including a large system for the management of medical equipment within the Central Manchester Healthcare Trust. This was integral to the activities of the Medical Engineering quality system and the hub of all department functions and procedures. This is an extensive program including software to enable management of a comprehensive equipment register, contract management, planned and emergency maintenance, ordering and stock management, staff and quality management. I also have considerable software experience with a wide range of software packages. These include all the core MS Office products such as MS Word, MS Excel etc. I am an experienced user of the scientific visualisation software AVS express. I have also used many other scientific and statistics packages including MATLAB, SPSS, EndNote and Origin etc. I am a skilled user of Corel Draw. My current research is in the application of neural networks in the analysis and classification of enteric manometry data using the NCS neural network program, NEUFrame.
