Personal profile

Biography

I completed my PhD (2006) at University College London, in which my thesis examined the cognitive mechanisms and the effect of interruptions on a specific form of human error known as post-completion error (think leaving your original in the photocopier after you have made your copies). In 2008, I joined the Centre for Health Informatics at UNSW, Sydney (now at Macquarie University) for a two-year postdoc on a project examining the effect of interruptions on doctors’ prescribing behaviour on computerized physician order entry (CPOE). I then took up an assistant professorship (2011 – 2020) at Lingnan University, Hong Kong.

Research

I am a psychologist specialising in healthcare human factors. My research aims to improve effectiveness and safety of healthcare technology and work practices adopted by healthcare professionals (e.g. doctors and nurses). While I use theories and methods from cognitive psychology to investigate the basic science behind identified applied problems, I also carry out clinical simulation studies to validate findings from laboratory-based experiments.

Current projects

My main research area is auditory displays, which are displays that use sounds to convey data information. I am currently investigating the effectiveness of speech-based sounds and how they might help clinicians monitor their patient’s vital signs (e.g. heart rate, oxygen saturation, etc.) while engaging in multitasking situations. The aim of this research is to provide an alternative to alarms when alerting clinicians to their patient’s deteriorating condition. One of the problems with alarms is that they are over abundant in hospitals; clinicians become desenitised to them (i.e. alarm fatigue) resulting in potential of missing real important ones.
