This searchable database of research faculty expertise is a collaborative effort of the Penn State Institutes of Energy and the Environment (PSIEE) and the Sustainability Institute. It is built around the PSIEE's original database of research expertise in energy and the environment, supplemented by additional faculty who self-identified their research as sustainability-related or sustainability-focused. We are working to improve the database through adding more refined search capabilities and additional faculty, especially in the sustainability realm.
