My research focuses on the health effects of environmental stressors, mainly outdoor air pollution. I have coordinated a EU network which provided European wide results on the short-term effects of air pollution (the APHEA network) and participated in projects investigating exposure to air pollution (e.g. EXPOLIS), gene-environment interactions (e.g. AIRGENE),air pollution effects in sensitive sub-populations (e.g. RUPIOH), health impact assessment (e.g. APHEKOM).
