My research in clinical epidemiology studies the effect on health of medical interventions in vulnerable populations during the perinatal period. My aim is to propose and evaluate strategies for optimising antenatal care in order to improve the short- and long-term outcomes of children born prematurely, taking into account that there is a continuum between the intrauterine, per-partum and postnatal periods. During my post-doctoral positions in Portugal and Switzerland, I developed another line of research focusing on social inequalities in health, particularly with regard to obstetric interventions differentiated between migrant and native women. In the wake of the pandemic, I focused my work on children and COVID-19, using a population-based approach. All these projects have enabled me to develop solid expertise in clinical research and epidemiological research methodology, particularly with regard to cohort studies, including digital studies.
