The WHO Collaborating Center (WHOCC) for Occupational Health at the University of Massachusetts Lowell was established in May 1996. The designation was obtained after a site visit from WHO/PAHO to the Department in 1995 and an interview with Chancellor William Hogan. The designation of the center has been effective since then, for periods of four years. Our latest re-designation was effective between September 2012-September 2016 and we are currently in the process of renewing this.
