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.
In our ongoing genetics projects, genome-wide approaches are primarily used (GWAS, global methylation analyses and RNA sequencing / microarray approaches) together with detailed clinical and epidemiological data. Extensive national and international collaboration is established (e.g. through the PERMEABLE, GABRIEL, EAGLE and MeDALL projects). We are also engaged in exposome-related research within the EXPANSE consortium. From this translational platform for advanced studies using clinical and epidemiological data sets, we are performing projects that will generate exciting new information in areas that have been little explored so far. For example, the long-term consequence of preterm birth and childhood exposures on lung function in young adulthood (CADSET ERS collaboration); identification of subgroups of the population that are particularly vulnerable to air pollution exposures; clarification of new genetic mechanisms for disease development.
