Simon is a human factors psychologist at the NIHR Diagnostic Evidence Cooperative (DEC) London, based at Imperial College. DEC London supports diagnostic test manufacturers in generating evidence to facilitate the adoption of their technology into clinical practise. Simon uses human factors methods, such as stakeholder analysis and clinical pathway mapping, to support this evidence generation.

Simon’s PhD, conducted at King’s College London, examined how health professionals handle interruptions – and how they multitask – in complex and dynamic clinical settings. His current research interests concern how technology can be designed to support the handling of competing demands.

Before his academic career, Simon worked for 10 years in industry (primarily healthcare and defence) as a behavioural scientist and management consultant. 

Simon is a chartered psychologist (British Psychological Society) and a member of the Chartered Institute of Ergonomics and Human Factors.
