Raymond has research interests within the broad area of biomedical and health informatics, which is the application of digital technology in healthcare. This has involved the modelling, processing and visualisation of medical data to enhance clinical decision-making (mainly involving cardiology data such as the ECG). He also has research interests in simulation-based training for medicine, usability engineering methods to improve medical devices (which include eye tracking and other psychophysiology metrics) and also Internet-based models for healthcare monitoring and interventions. Raymond also coordinates a UX-Lab which is an outlet for transferring usability engineering knowledge to the medical device industry and other industries. Raymond has been a grant holder on research projects funded by FP7 and H2020 programmes, InvestNI, Innovate UK, InterTrade Ireland and the Royal Irish Academy.
Raymond obtained his BSc and PhD in the School of Computing and Mathematics (Ulster University). Before his academic appointment, he worked in the IT industry as a Web Programmer and later held Research Associate positions in the subject areas of Connected Health and Computerised Electrocardiography. Subsequently, he coordinated the Computing and Engineering Professional Education Centre for Northern Ireland (CEPEC-NI) where he managed computing science courses and outreach activities.
