Research groups are formed around central and important themes. They are centered in the School but include affiliated faculty and staff from USGS, INR-P and other PSU departments. These research groups are formalized collaborations between our core faculty and PhD students, and are used to decide on areas for new faculty hires and seek funding for infrastructure improvements. Faculty participating in these research groups are the best way for PSU to identify emerging areas of scholarship and applied research to pursue. Some of the groups listed here are already active and others are being developed.
