I’m an interdisciplinary researcher and practitioner health psychologist working at the intersection of behavioural science and technology. I’m a Senior Research Fellow in the UCL Tobacco and Alcohol Research Group. My research is focused on the development, optimisation and evaluation of interventions for smoking cessation and alcohol reduction delivered via smartphone apps, chatbots, virtual reality and in hybrid human-digital format. I’m interested in the technology-enabled, real-time assessment and modelling of within-person processes and associated ‘just-in-time adaptive interventions’.
