Biography

Jan Jansen is a consultant in general surgery and intensive care medicine at Aberdeen Royal Infirmary, an honorary clinical senior lecturer at the University of Aberdeen, and an NRS (NHS Research Scotland) fellow, affiliated with the Health Services Research Unit. He also works, part time, as an honorary consultant trauma surgeon, at St Mary's Hospital in London.

His undergraduate training took place in London. He subsequently moved to Scotland for his postgraduate general surgical training, and also completed clinical fellowships in trauma surgery in Johannesburg, and critical care medicine in Toronto.

Jan Jansen's main interest is trauma care.

Research

Research Interests

  • Organisation of trauma care, with particular reference to the effects of geography
  • Trauma resuscitation.

Current Research

"A Geospatial Evaluation of Systems of Trauma Care for Scotland" - a programme of research to determine a geospatially optimised configuration of trauma system for Scotland, balancing the conflicting objectives of accessility and specialist care. The project draws on a combination of prospective pre-hospital data collection, travel time  analysis, whole-system mathematical modelling, and multi-objective optimisation.
