Division of Applied Research and Technology

The Division of Applied Research and Technology (DART) provides national and international leadership in research focused on the prevention of occupational illness and injury by developing and evaluating:

  • Methods and tools to identify and quantify workplace hazards (chemical, biological, physical, organizational);
  • Strategies and technologies to control exposures to workplace hazards.

Through information sharing, demonstrations, and partnerships, DART chemists, engineers, biologists, toxicologists, psychologists, and other scientists provide focal points for field and laboratory research in a diverse range of activities:

Exposure Sciences

DART assesses worker exposures to toxic agents with cutting-edge sampling techniques using state-of-the-art aerosol science, analytical chemistry, and biomonitoring methods. This research provides methods used worldwide for the identification and characterization of complex workplace exposures to chemicals, biological agents, and particulate matter.

Engineering and Control Technology

DART conducts research to identify, evaluate, develop, and implement technology to prevent worker exposure to workplace hazards. Research includes workplace studies and computational fluid dynamic modeling for the design and evaluation of controls, and investigation of hazards associated with emerging technologies and changing workplace environments.

Work Organization and Stress-Related Disorders

DART conducts research to determine how organizational practices influence risk factors that lead to stress disorders and other workplace illnesses and injuries. Develops and evaluates interventions to reduce the economic, social and organizational burdens associated with these disorders.

Noise Control and Hearing Loss Prevention

This research encompasses basic etiology of hearing loss, ototoxicity, control technologies for control of noise sources, personal protective equipment and hearing loss prevention programs.


DART conducts research on human factors, biomechanics and work physiology, environmental and neurobehavioral stressors, lifting and upper extremity exposures, and work capacity. This research develops tools and strategies for preventing work-related musculoskeletal disorders.

Male and Female Reproductive Health

Through workplace assessments, epidemiologic studies, and laboratory investigations, DART conducts research on the effects of various chemical and physical exposures on the reproductive health of both women and men.
