The AAU held a workshop on STAR METRICS for Senior Research Officers on October 25-26, 2011. Nearly 40 AAU institutions were represented at the workshop. An opening address was given by Irwin Feller, Professor Emeritus of Economics at Pennsylvania State University. Feller put STAR METRICS in historical context and talked about both the promises and the perils of attempting to measure the return on federal investment in research. He also laid out a set of questions about efforts like STAR METRICS that he hoped would be useful to the discussion.
