Environmental challenges aren’t bound by borders. In response, Harvard Extension School is incorporating interdisciplinary collaboration, global perspectives, and international concerns into the curriculum, says Michael Mortimer, the new director of HES’s Sustainability and Global Development Practice Programs.

Mortimer founded the Center for Leadership in Global Sustainability at Virginia Tech, helping to establish educational programs in Argentina, India, China, Cuba, South Africa, and across the European Union before coming to Harvard. He is also co-author of “Leadership for Sustainability: Strategies for Tackling Wicked Problems.” He spoke with the Gazette about his strategy.
