About

Sarah Lim Choi Keung is a research fellow in health informatics and a visiting academic at the university. She works closely with members of the School of Health and Population Sciences and the Primary Care Clinical Research and Trials Unit. Sarah works in the areas of health and clinical research informatics, supporting patient cohort identification and recruitment to clinical studies and trials by linking heterogeneous primary care and secondary care data. She is also interested in semantic interoperability issues in the healthcare domain. With a background in computer science, her other research interests are in agent-based systems, the concepts of trust and reputation, and the human-computer interaction. 

Qualifications

  • PhD in Computer Science, University of Warwick, 2011
  • MSc in Advanced Computer Science, Lancaster University, 2005
  • BSc (Hons) in Computer Science, University of KwaZulu-Natal, 2003
  • BSc in Computer Science and Information Systems, University of South Africa, 2002

Biography

Sarah is working on several research projects aiming to support clinical research, e.g. by facilitating the recruitment of patients to studies and trials by investigating data linkages in primary and secondary care. Project partners and collaborators include the EU TRANSFoRm project partners; the Birmingham and Black Country Comprehensive Local Research Network, NHS PCTs and secondary care research specialty groups across the West Midlands.

She has completed a PhD in Computer Science, in the area of trust and reputation in agent-based systems at the University of Warwick. Her PhD work includes supporting collusion detection by agents, using routine interaction and recommendation information while consolidating their knowledge of agents’ social networks.

Previously, Sarah obtained BSc and BSc(Hons) degrees in Computer Science from the University of South Africa and the University of KwaZulu-Natal, South Africa, respectively. She was then involved in teaching at undergraduate level in Mauritius at the Charles Telfair Institute, before going on to study for a Masters degree in Computer Science at Lancaster University.
