The Office of Sustainability is here to help those in the WPI community looking to have a bigger part in sustainability on campus or in their lives.

From our office staff who run the day-to- day operations, to our volunteer WPI Eco-Reps who can answer any questions that you have about sustainability efforts in your on-campus building, to our Sustainability Advisory Committee who provides leadership and coordination for WPI's campus-wide efforts, feel free to reach out to us on how you can get involved.

Our Staff


Professor Mathisen joined the Office of Sustainability as Director in 2018, and he continues to teach and conduct research in the areas of water resources and environmental engineering. He enjoys challenging himself to learn new ideas and concepts, which he can then apply to solve problems that can make a difference for other people. WPI's curriculum and projects program provide the perfect environment for fostering these opportunities. Paul looks forward to working with WPI students, faculty, and staff to further sustainability initiatives across the curriculum and in the WPI, Worcester, and global communities.

Sustainability Advisory Committee

The purpose of the WPI Sustainability Advisory Committee, led by Director of Sustainability John Orr, is to provide leadership and coordination for WPI's campus-wide efforts in energy and resource conservation, economic security, and social well-being. We are an educational institution; thus, these goals are interwoven with our academic goals in teaching about the practices of sustainable design and the impacts of behavioral changes, as well as in conducting research in the reduction of environmental impacts and in methods of enhancing sustainability. The committee is drawn from, and works with, all segments of the WPI community: students, faculty, and staff. Further, since WPI is an active member of the local, regional, and world communities, the work of this committee will have impacts beyond the WPI campus.
