From 1982 to 1997 he was director of the National Institute for Occupational Safety and Health (NIOSH) Educational Resource Center in Occupational Safety and Health at Johns Hopkins University.

In 1975, he was appointed Assistant Secretary of Labor and head of Occupational Safety and Health Administration (OSHA). He opines that the amount of asbestos in the air from brake mechanic work at any given time based on time weighted average studies is insufficient to warrant a conclusion that they cause disease. He speaks in terms of dose exposure, peak exposure levels, and time weighted measurements.
