11/12/2025: Current International Research Efforts for Traditional Occupational Aerosol Samplers

Darrah Sleeth, PhD, MPH, CIH is a Professor in the Division of Occupational & Environmental Health and the affi liated Rocky Mountain Center for Occupational & Environmental Health at the University of Utah (UofU). She has been at the UofU since 2010 and currently serves as the Industrial Hygiene Program Director. She earned a PhD in Industrial Health and an MPH in Industrial Hygiene & Hazardous Substances from the University of Michigan, as well as a BA in Integrative Biology from the University of California, Berkeley. She has also qualified as a Certified Industrial Hygienist (CIH). Her research interests include exposure assessment for airborne respiratory hazards, particle size selective sampling methods, and indoor air quality. Her laboratory work has involved the design of a low-speed wind tunnel for controlled exposure studies, which has subsequently been used for air sampler design and testing. With this facility, her work has focused on performance studies of existing equipment and development of novel air samplers, which have subsequently been used for fi eld research as well. Her fieldwork is focused on understanding occupational and environmental exposures in a variety of settings, with ongoing collaboration from government, industry, community, and tribal partners.
