Gaby Judah is a psychologist working on behaviour change in the Patient Safety Translational Research Centre (PSTRC) at the Institute of Global Health Innovation, Imperial College London.  Work within PSTRC focuses on the applying behavioural sciences to the theme of Safer Systems across the Transition of Care. She completed her PhD from the London School of Hygiene and Tropical Medicine (LSHTM) in 2014, investigating the psychological determinants of habit formation of health related behaviours.  Gaby completed an MSc with distinction in Research Methods in Psychology from UCL.  

Present research

Current projects include reducing burnout in clinicians, investigating determinants of medication adherence particularly in patients with hypertension and those taking statins, increasing cancer screening uptake, promoting physical activity in breast cancer survivors to reduce recurrence, and improving the discharge process to ensure safer transitions between secondary and primary care. 

Recent work has tested the impact of different types of financial incentives on attendance at diabetic eye screening appointments. 

Research interests

I am interested in applying behaviour change principles to improve the health of patients and the public, and to improve patient safety. To achieve this, my work focuses on learning about predictors of health related behaviours, as well as how to apply these to encourage sustained behaviour change.
