Final year PhD student at the University of Glasgow, exploring how to increase efficiency when evaluating health apps and wearables for behaviour change.

I use an interdisciplinary approach combining methods from health and human computer interaction/computing science.  Particular interest in automating Single Case Designs / N-of-1 trials (as an alternative to randomised controlled trials), and the use of user logs and online app stores to remotely test if an app changes behaviour.


I’m working within both the Institute of Health and Wellbeing and School of Computing Science (Human Computer Interaction GIST group), supervised by Dr Cindy Gray, John Rooksby and Matthew Chalmers.

I completed my Undergraduate degree in Psychology (also at the University of Glasgow).  I have been awarded 4 years of funding for the PhD (until 2018) through a Lord Kelvin Adam Smith Scholarship (which supports interdisciplinary researchers).


  • Mobile health apps and wearables (as an intervention and/or remote monitoring tool)
  • Evaluating the real-world effectiveness of complex behaviour change (inc. physical activity) interventions
  • Experimental design and data collection methods
    • Single Case Designs / N-of-1 trials
    • Continuous sensor data
    • Fully-remote “virtual” automated research trials (from recruitment to real-time analyses)
    • Process evaluations, feasibility studies, evaluability assessments
  • Individual-level outcomes:  self-experimentation and citizen science models, user-centred approaches, personalized medicine.
  • User Experience
  • Stakeholder involvement in evaluations (academic disciplines, academic-industry collaborations, users…)
  • Scoping reviews, systematic reviews (and automating these)
  • Practical challenges associated with evaluating digital health tech
