PSERCActivities of interest

• Reviewing project progress in separate meetings (using distance conferencing or net facilities/services) that will take place in-between the IAB meetings (42)

• Making sure the final reports for completed PSerc projects are properly reviewed and advertised (37)

• Producing a list of research areas of interest for the solicitation of new proposals (37)

• Conducting the review process and ranking of the proposals (32)

• Initiating review of the Statement of Work (SOW) documents for the projects in similar research areas making sure the coordination of the research activities is optimized (18)
