Our client was an engineer doing academic research in a very specific niche. The number of researchers in the area is small; this and other factors resulted in our client having only a few citations. However, he had been a peer reviewer for a federal grant program several years running. When we received a Request for Further Evidence of impact, we were able to show how his review activity was relevant. In addition, we provided an analysis of the citation figures showcasing his influence in the field, and the case was approved.
