I am a Senior Researcher at the Comprehensive Health Research Centre, NOVA Medical School, and I am a visiting research fellow at Trinity College Dublin and Centre for Behaviour Change, University College London. I am a member of the Portuguese Behavioral Science COVID-19 Task Force, and of the Executive Committee of the European Health Psychology Society. Before this position, I was a Marie Sklodowska-Curie Fellow at Trinity College Dublin. I obtained my PhD in Health Psychology from Leiden University, and I am a chartered clinical and health psychologist. My achievements have been recognised by two very prestigious international early career awards from the European Health Psychology Society and International Society of Behavioural Nutrition and Physical Activity, as well as by invitations to join important expert commissions, such as the leading team responsible for developing the WHO global digital program for physical activity (B@Healthy B@Mobile mActive). My research focuses on applying health behaviour change theories to develop and evaluate complex digital interventions targeting a range of health behaviours (e.g. physical activity), and in advancing the methods for the development of the science of behaviour change.
