A founder of multiple companies himself, Jesko von Windheim was already teaching entrepreneurship courses at Duke when he recently joined the Nicholas faculty to lead the new environmental entrepreneurship certificate program. Classes in the two-year program will train students to understand business models and financial statements, use case studies of real entrepreneurship and translate an academic idea into a virtual start-up. In this "Office Hours" interview, he talks about how to teach entrepreneurship, how businesses can grow out of research and where the green of environment and money meet.
