g-index

The g-index is a metric used to measure a researcher's scientific impact based on their published work and citations. It considers both the number of publications and how often those publications are cited by others, giving more weight to highly-cited papers. Specifically, a researcher has a g-index of "g" if they have published enough papers such that their top "g" papers have collectively received at least "g" squared (g²) citations. This helps gauge not just productivity but also the significance and influence of their most impactful work.
