Stephen is Senior Research and Strategy Advisor at the Irving Institute for Energy and Society where he is focused on fostering interdisciplinary efforts to tackle pressing multidimensional challenges at the interfaces of energy and society. He also supports engagement and collaboration with groups outside the College, grant opportunities and developing the campus as a living laboratory for energy education and leadership. Prior to his arrival, Stephen was on the senior leadership team at Rocky Mountain Institute for over 10 years. While there he led research and applied efforts in areas ranging from low carbon strategies for states and utilities to designing and building a data center to reduce its energy use by 80%. He also led teams in building retrofits (e.g. the Empire State Building), carbon fiber car components, efficient oil refining, and low cost solar PV systems. Most recently he founded and led RMI's efforts to bring sustainable energy for economic development (SEED) to African nations, established the Institute's program in the Caribbean Islands (including Puerto Rico) and whole system design effort to make community scale solar affordable.
