In her 2014 commencement remarks to 2,700 graduates at the Massachusetts Institute of Technology (MIT), DuPont Chair & CEO Ellen Kullman shared thoughts on how being an engineer has prepared her to solve problems. "I approach the problem like the mechanical engineer I am," Kullman said. "I think about how heat, light and water can make a difference. It's a focus that I have used throughout my career and life, and I want to share it with you."
