Raymond has research interests within biomedical and healthcare informatics, which is the application of digital technology in healthcare. This is otherwise known as digital health. Raymond's work involves the application of human-computer interaction and data science 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 decision support systems. He also has research interests in computerised simulation-based training in healthcare, usability engineering methods to improve medical devices, eye-gaze analytics in decision science, and is also invovled in developing computerised models for healthcare monitoring and interventions. 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, MRC, HSC, FP7, H2020, InvestNI, Samaritans Ireland, Innovate UK, Higher Education Academy, InterTrade Ireland and the Royal Irish Academy. Raymond is a Senior Fellow of the HEA and he obtained his BSc(hons) 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.
