Jakob Löndahl is a professor in aerosol technology at the Department of Design sciences at Lund University and director of the Aerosol and Climate Laboratory at LU. The research, teaching and science communication he is working with are related to medical and health applications of aerosols: airborne particles in the lungs, transmission of airborne disease, inhalation and deposition of air pollution in the respiratory tract, detection of lung disease by use of aerosols, aerosol measurement techniques and biological aerosols. He received a PhD in Physics in 2009 and thereafter carried out postdoctoral studies on biological aerosol particles at McGill University, Canada, and Aarhus University, Denmark. Since then, he has been working at the Division of Ergonomics and Aerosol Technology at LTH. Together with Prof. Per Wollmer he is inventor of the Airspace Dimension Assessment (AiDA), which is a novel instrument for detection of lung disease.
