About
Jorma Keskinen is a leading environmental health researcher whose work focuses on the intersection of indoor air quality, microbial exposure, and human health, particularly during early childhood. His major contributions center on understanding how human activity—such as crawling and walking—resuspends biological particulate matter (bioPM) from floor dust, creating a dynamic and often overlooked source of inhalation exposure. Keskinen’s research has been instrumental in revealing that the infant breathing zone is uniquely affected by this resuspension, with his highly cited 2017 study (81 citations) demonstrating that resuspended floor dust is a major indoor source of bioPM, including allergens and microbes linked to both adverse and protective health effects. His 2018 work (61 citations) further advanced this field by showing that crawling-induced resuspension significantly alters the microbiota in the air immediately surrounding infants, challenging traditional methods of using settled floor dust alone for microbial exposure estimates in epidemiological studies. Through these impactful investigations, Keskinen has reshaped our understanding of indoor exposure pathways, highlighting the critical need to consider resuspension dynamics in studies of asthma, allergies, and immune development.
