Dr Nathan Lea

I am a Senior Research Associate working with the Electronic Healthcare Records (EHR) group at CHIME on projects that involve the use of EHR servers in research and clinical care. My research interests include the role of information systems in supporting healthcare delivery and empowering patients, and Information Governance in the use of distributed computing for managing healthcare data.

I have completed a PhD supervised by Professor Dipak Kalra (CHIME, UCL) and Professor Stephen Hailes (Department of Computer Science, UCL). The research evaluated the effects of using knowledge management to represent policy based controls on participants' behaviour when handling healthcare information for clinical research. The results of this work have been the invention of the knowledge model called the Secutype and a policy tool to guide researchers on how to handle healthcare records in accordance with security policies when they are used for clinical research.

I teach on the Information Law and Governance In Clinical Practice and eHealth modules of CHIME's Health Informatics MSc and courses in UCL’s MBBS. I have co-developed and deployed clinical information systems used at Whittington Health for Cardiovascular care and Dementia registries in partnership with the West London Mental Health Trust and UCL’s Dementia Research Centre.

In my spare time I enjoy swimming, climbing and cycling and I have competed in open water swims and a half marathon. I have set my sights on the 2016 London Triathlon and learning how to Salsa...

Personal History

I received a BA (Hons) in Classics from The Department of Greek and Latin, UCL in 2001. I have worked in the area of IT in healthcare since 1998. In 2002 I enrolled on an MSc Conversion Course with the Department of Computer Science, UCL to expand my knowledge of computing. During this course, I applied my working and research experience to the study of Health Informatics by completing a dissertation with the EHR group at CHIME. After working in the private software development sector, I joined the EHR group at CHIME as a Research Fellow and completed a PhD part time.
