Academic Bio

Darrah Sleeth, PhD, MPH, CIH is an Associate Professor at the Rocky Mountain Center for Occupational & Environmental Health. 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. She was involved in the design and use of a unique low speed wind tunnel and breathing mannequin system to assess both the inhalability of airborne particles and the performance of air sampling devices. She is also active with international standards setting organizations in the development and improvement of sampling strategies for workplace air quality.

Research Statement

My overall research goal is to improve exposure assessment for occupational and environmental stressors in order to keep workers and the community healthy. Improved exposure data should lead to a more accurate understanding of the relationship between exposures and health outcomes. My 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, my work has focused on (1) performance studies of existing equipment and (2) development of novel air samplers, which have subsequently been used for field research as well. My fieldwork is focused on understanding occupational and environmental exposures in a variety of settings, with ongoing collaboration from government, industry and community partners.
