The h-index is a metric used to measure the productivity and citation impact of an individual researcher’s scholarly publications. It aims to quantify both the number of publications and their influence by identifying the maximum number 'h' such that the researcher has published at least 'h' papers each cited at least 'h' times. Widely used in academia, the h-index provides a combined indicator of research output and impact.
