In the 1970s and 80s, Dockery led the Harvard Six Cities study, the results of which were published in 1993 in the "New England Journal of Medicine". In the study, Dockery and his co-authors (including C. Arden Pope) reported that air pollution was associated with increased mortality. The results of this study have been used by the Environmental Protection Agency as the basis for their regulations on fine particulate matter in 1997, and, as of 2005, was the  most-cited air-pollution study ever published. In 2009, Dockery co-authored another study which found that improvements in air quality in 51 American cities had led to life expectancies of people living there increasing by as much as five months.
