My research projects aim to advance the understanding about the complex interplay between genetic and environmental factors involved in lung growth, respiratory and allergic diseases in children. The projects are primarily based on a Swedish birth cohort, BAMSE that allows for unique investigation of lung function, respiratory and allergic diseases in a large number of children up to adulthood. Detailed information about perinatal events, environmental exposures such as air pollution and tobacco smoke exposure from birth and onwards has been collected. Currently, we are also performing a targeted COVID-19 follow-up of the cohort.
