Mark Hoover, CDC/NIOSH

Mark D. Hoover is a senior research scientist in the Division of Respiratory Disease Studies at the U.S. Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH), in Morgantown, West Virginia.  NIOSH is the leading U.S. federal agency conducting research and providing guidance on the occupational safety and health implications and applications of nanotechnology.  Mark is Co-Director of the NIOSH Center for Direct Reading and Sensor Technologies, coordinator of the NIOSH Exposure Assessment Cross-sector Research Program, and a critical area leader in the NIOSH Nanotechnology Research Center.  Prior to joining NIOSH in 2000, Mark was an aerosol scientist for 25 years at the U.S. Department of Energy’s Lovelace Respiratory Research Institute in Albuquerque, New Mexico.  Mark earned a BS degree in mathematics and English in 1970 from Carnegie Mellon University and MS and PhD degrees in nuclear engineering in 1975 and 1980 from the University of New Mexico.  He is board certified in the comprehensive practice of health physics and in the comprehensive practice of industrial hygiene.  Mark has served as chairman or contributor to the development of many national and international standards, is a past chairman of the AIHA Nanotechnology Working Group, and is author or co-author of more than 200 open literature publications.  He chairs the National Council on Radiation Protection and Measurements (NCRP) Scientific Committee 2-6 on Radiation Safety Aspects of Nanotechnology and is project leader for the International Electrotechnical Commission (IEC) technical report on Radiation Instrumentation Issues for Airborne Materials including Nanoparticles.  Special emphasis areas for Mark’s work in sensors, nanotechnology, and nanoinformatics include a graded approach to exposure assessment and characterization of nanoparticles in the workplace, development of a prototype Nanoparticle Information Library, and promotion of opportunities to apply informatics and performance-based occupational exposure limits or control banding approaches to nanotechnology.  Detailed information about the NIOSH Center for Direct Reading and Sensor Technologies and the NIOSH nanotechnology health and safety research program is available at and at

National Institute for Occupational Safety and Health


The National Institute for Occupational Safety and Health (NIOSH) was created by the Occupational Safety and Health Act of 1970 and is part of the Centers for Disease Control and Prevention (CDC).  NIOSH is the only Federal agency tasked with conducting research to prevent worker injury and illness.  The Institute’s work in this area protects the safety and health of the nation's 155 million workers.  NIOSH provides the only dedicated federal investment for research needed to prevent the societal cost of work-related fatalities, injuries and illnesses in the United States, estimated in 2007 at $250 billion in medical costs and productivity losses alone.

NIOSH development and application of sensors addresses hazards and exposures ranging from noise, chemicals, and radiation to stress, ergonomics, and work flows.  For all types of hazards in the workplace, the objective is to enable operators to anticipate and quickly identify potential overexposures and implement interventions to prevent these overexposures.  In May 2014, NIOSH created the Center for Direct Reading and Sensor Technologies.  The primary goals of the Center are to develop guidance for appropriate use, validation, and interpretation of direct reading and sensor technologies and will also focus on coordinating a national agenda for their effective application in occupational safety and health.

NIOSH conducts projects internally through its intramural research program, and NIOSH funds projects for external partners through the NIOSH extramural research grant program.  NIOSH intramural research includes a number of projects to develop or improve hazard or exposure-specific sensors or to use multiple sensors in combination to improve exposure assessment and to reduce workplace exposures.

A recent sensor development example related to concerns for respirable dust in mining is the personal dust monitor (PDM), which is a real-time dust monitor that was developed by NIOSH through intramural and extramural research over the last decade.  Extensive NIOSH testing has demonstrated that the PDM is an accurate dust sampler, and the U.S. Mine Safety and Health Administration (MSHA) has specified that the PDM will be used for compliance dust sampling in its new respirable dust regulations, which have just completed the final stages of the rulemaking process.  The PDM is a research-to-practice success story.  Additional information about the PDM can be found at:

Information about funding opportunities provided by the NIOSH Grants Program can be found at:  Current extramural research grants in the area of sensors include biosensors for different chemical exposures, wearable monitors for a variety of work sites, monitors that can be used in exposure characterization studies for ultrafine and nanoparticles, and noise dosimeters.
