The ERS Lung Science Conference (LSC) is a showcase for cutting-edge research and its translation into clinical solutions. Its originality and success are based on facilitating dialogue between young scientists and established investigators. The programme is made of presentations by experts, oral presentation based on abstracts and poster sessions. After each presentation, time is allocated to questions and discussion. Specifically, the Lung Science Conference 2020 is intended to present the latest advances in basic and translational research in the field of metabolic alterations in lung ageing and disease. Special features for early-career delegates will also be organised, such as a session entitled “Strategically and successfully funding of your future” and the usual LSC mentorship programme.
