About

Tianren Wu’s research pioneers our understanding of how human activity stirs up hidden health hazards indoors. His work centers on the physics of particle resuspension and the resulting inhalation exposure, with a particular focus on biological particulate matter (bioPM) and its outsized impact on vulnerable populations. Wu’s landmark 2017 study, cited 81 times, revealed that simply walking across a floor can dynamically re-aerosolize dust laden with microbes and allergens, transforming a static reservoir into a major source of indoor bioPM. He then broke new ground by targeting the infant near-floor microenvironment. In a clever 2021 study (28 citations), Wu deployed a robotic infant in chamber experiments, demonstrating that babies—due to their proximity to the floor and unique activity patterns—face disproportionately high exposure to resuspended carpet dust. By integrating these experiments with material balance models, he quantified the heightened inhalation risks for early childhood development. Wu’s contributions are foundational to indoor air quality science, directly informing strategies to mitigate exposure in homes and childcare settings. His work is essential reading for anyone studying the intersection of aerosol science, microbiology, and children’s environmental health.
