Bioaerosols are e.g. bacteria, fungi, pollen, and viruses that are aerosolized by different natural processes, such as winds, breaking of ocean waves, or by various human activities, such as coughing. We study experimental aerosolization of model viruses and different properties of airborne virus transmission. We develop air sampling techniques and perform simulations of bioaerosol formation and dispersion. Our research aim is to gain knowledge on the various roles microorganisms have in the atmosphere. Our research is conducted at University of Helsinki and Finnish Meteorological Institute. See more about our collaboration network and funding.
