Mr Nathan Lea

Work Interests

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 security in the use of distributed computing for managing healthcare data. I am currently working on a PhD supervised by Professor Dipak Kalra (CHIME, UCL) and Professor Stephen Hailes (Department of Computer Science, UCL): the thesis of the research is that it is possible to construct a knowledge management framework to comprehensively manage policy based controls that govern the release of information from clinical data repositories. One of the results of this work has been the invention of the knowledge management formalism called the Secutype, which underpins a significant part of the proposed framework. I also teach on the Information Law and Governance In Clinical Practice Module of CHIME's Health Informatics MSc.

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 formalise 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.
