Researcher Identity & Impact

This guide is designed to assist you with expanding the impact of your research by developing your researcher profile and explaining how metrics work.

Author-level metrics


  • h-index: calculated by using the total number of articles (h) published to date by an author and the number of citations, identifying how many of these articles pass over that number to be included in the index.

E.g. Author A has an h-index 9. This means he/she has published at least 9 articles, every one of which has been cited at least 9 times.

  • i10-index: calculated by taking the number of articles that an author has published to date (i) and then finding out how many of those articles have generated at least 10 citations.

E.g. Author A has an i10-index 9. This means that at least 9 of his/her articles have been cited at least 10 times.

  • Citation counts: The total sum of citations for all articles of an author.

E.g. Author A has citation count of 87. This means that you need to add up all times his/her work has been cited to calculate the Citation count.

What is the idea?

The more the author publishes and the more his/her work is being cited by other authors, the higher the index.

The idea for quantifying the impact of a researcher has always been a hot topic. Despite the drawbacks of the author-level metrics, the h-index and i10-index are fast-growing and frequently used.

Where to find them?

Scopus, Web of Science and Google Scholar and some other free online ranking resources.
