Professional Summary

Rick Neitzel is an exposure scientist whose research focuses on the characterization of exposures to noise, heavy metals and other ototoxins, psychosocial stressors, and injury risk factors, as well as a range of adverse health effects associated with these exposures. His work, and the work of his team in the UM Exposure Research lab, takes place in occupational and community settings both domestically and abroad. He is particularly interested in incorporating new methodologies and exposure sensing technologies into research, and also has a strong interest in translating his research findings into occupational and public health practice.  He directs the UM Risk Science and Human Health Certificate program, and is also Director of the Pilot Project Research Grant Program of the UM Center for Occupational Heath and Safety Engineering.

Prior to his appointment to the faculty of the UM Department of Environmental Health Sciences and to the UM Risk Science Center, he worked as a Reseach Scientist in the University of Washington Department of Environmental and Occupational Health Sciences from 1998-2011.  He has been a Certifed Industrial Hygienist since 2003.

Research Interests & Projects

Neitzel Laboratory - Physical Hazards
Principal Investigator: Rick Neitzel, PhD

There is currently a great deal of focus in occupational and environmental health on emerging technologies and their potential impacts on human health. However, as important and intriguing as these emerging issues are, there are many existing hazards that we have known about for years, decades, and even longer, and yet continue to grapple with. 

To help address these important human health issues, the research of the Physical Hazard Lab focuses on the application of novel exposure- and health-related sensing technologies to evaluate exposures to noise and other physical hazards; on assessment of auditory and non-auditory health effects associated with noise exposure and exposure to ototoxic agents; and on characterization of injury risk associated with noise exposure and transportation-related activities, with a particular focus on bicycling.
