|Dr. Reponen’s research is focused on the exposure assessment of bioaerosols in indoor and industrial environments, including physical and microbiological characterization of airborne actinomycete and fungal spores, the dispersion of bioaerosols under natural and laboratory conditions, and the control of airborne microorganisms by filtration. She is a Certified Indoor Air Quality Professional, and in her field studies, she is collaborating with epidemiologists in investigating the health effects of particle and bioaerosol exposures. She is currently directing two cohort studies. One is focused on the association between indoor bioaerosol exposures and the development of children’s allergy and asthma and the other is focused on the effects of green renovation on indoor air quality and occupants’ health. She is the Director of the NIOSH-funded University of Cincinnati Education and Research Center and teaches in the Environmental and Occupational Health graduate program. She serves as an Editor for the Aerosol Science and Technology journal and as an Associate Editor for the Indoor Air Journal. She is a member of the Occupational Safety and Health study section. She is a recipient of Finland Distinguished Professor (FiDiPro) award.
