Raymond has research interests within human-computer systems which has mainly included applications of biomedical and healthcare informatics (digital health). Raymond's work has involved the application of human-computer interaction and data science/machine learning techniques to healthcare research. His work has involved health data analytics as well as the modelling, processing and visualisation of medical data to enhance clinical decision-making, including the creation of interactive decision support systems. He also has research interests in computerised simulation-based training in healthcare, usability engineering/UX data analysis methods to improve medical devices, eye-gaze analytics in clinical decision making, and is also involved in designing and evaluating digital health and wellbeing interventions. Raymond has over 350 research outputs and has chaired/co-chaired a number of conferences: 1) 32nd International BCS Human Computer Interaction conference, 2) the 45th/ 46th Annual Conference of the International Society for Computerised Electrocardiology, and 3) the 31st Annual European Conference of Cognitive Ergonomics).
Raymond initiated 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 EPSRC, ESRC, HSC, FP7, H2020, InvestNI, Samaritans Ireland, Innovate UK, Higher Education Academy, InterTrade Ireland and the Royal Irish Academy.
Raymond obtained his BSc(hons) and PhD in the School of Computing and Mathematics (Ulster University). He is a senior fellow of the UK higher education academy. Before academia, he worked in the web industry and later held Research Associate positions in the subject areas of Connected Health and Computerised Electrocardiography. He also coordinated the Computing and Engineering Professional Education Centre for Northern Ireland (CEPEC-NI) where he managed computing science related outreach activities and summer schools.
