The first contribution of the three-part study found that, based on an examination PHOTO / DONNA COVENEY of the European Union’s system and of similar U.S. programs for other emissions, Herman addresses Diversity Leadership Congress such a program Former Secretary of Labor Alexis Herman delivers the keynote address Nov. 18 at the Diversity Leadership Congress, which can indeed be effective in aimed to promote a culture of diversity at MIT by bringing together academic, administrative and student leaders.
