Author-level metrics attempt to quantify impact by analyzing citations arising from an individual author's publications.
The h-index (Hirsch index) measures the impact of a particular scientist rather than a journal. It takes into account the number of papers published and the number of citations received by these papers resulting in a single number rating. For example, a scholar with an h-index of 5 has published 5 papers, each of which has been cited by others at least 5 times.
Note that an individual's h-index may vary between databases. This is because different databases index different journals and cover different years. For instance, Web of Science calculates an h-index using the years 1985-present. Google Scholar Citations covers a different set of years and journals.

Disadvantages:
Use Web of Science's Author Search to find all the publications by a particular author and create a Citation Report showing the author's most highly cited articles, citation trends, average citations per article and other metrics, including the h-index.
