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.
Current projects include reducing burnout in clinicians, improving the discharge process to ensure safer transitions between secondary and primary care, and increasing uptake of innovations to improve healthcare.
Additional projects include investigating determinants of medication adherence particularly in patients with hypertension, increasing cancer screening uptake, and promoting physical activity in breast cancer survivors. Recent work has tested the impact of different types of financial incentives on attendance at diabetic eye screening appointments.
I am interested in applying behaviour change principles to improve patient safety, and the health of patients and the public. 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.
