Rate My Professor Darrah Sleeth

Sleeth's research specializations include exposure assessment for airborne respiratory hazards, particle size selective sampling methods, and indoor air quality. She has pioneered the design of a low-speed wind tunnel and breathing mannequin system to evaluate particle inhalability and air sampling device performance under realistic workplace conditions. Her work also features community-based participatory research on environmental exposures in tribal populations. In 2024, she received a $1.55 million NIH grant to develop environmental health communication strategies for rural tribal communities. Sleeth has authored or co-authored over 47 publications from 2008 to 2025. Key contributions include "Visualization of the airflow around a life-sized, heated, breathing mannequin at ultralow windspeeds" (Schmees et al., 2008, Annals of Occupational Hygiene), "Performance study of personal inhalable aerosol samplers at ultra-low wind speeds" (Sleeth and Vincent, 2012), "A Simple and Disposable Sampler for Inhalable Aerosol" (L'Orange et al., 2016), and "Environmental and Occupational Health on the Navajo Nation: A Scoping Review" (Coombs et al., 2021).
