Mark approaches both his life and his work with infectious energy and joy. Students in his courses at Grenoble Ecole de Management and at the Harvard Extension School rave about the impact he has on their lives and learning. As Founder & Director of the Lab-Center for Competitiveness, he and his colleagues think deeply and write prolifically about how to create a world that is more equal from the bottom up. When he is not changing the world, he defends his wife and dog with his expertise as a fourth dan black belt.
