The h-index is a measure of both productivity and impact of ones published works. It looks at the total number of papers you have published, and the number of citations those papers have received. It is based on the highest number of papers included that have had at least the same number of citations.

For example, if you've published 2 papers, and each paper has been cited 2 times, you will have a h-index of 2.

What if it's a little more complicated, where your published papers have range of both high and low citations? Let's say you've published 5 papers altogether, one cited 5 times, one 4 times, one 3 times, one 2 times, and one just the 1 time. You will have a h-index of 3. That is to say, you cannot claim higher (4 papers cited 4 times each).

Thus the h-index attempts to measure the impact of your output - you need to have published a large number of papers, which were in turn cited a large number of times, to have a high h-index.

This metric can be found using Scopus, Web of Science, or Google Scholar.

**Limitations of h-index**

The h-index is not appropriate for comparing across disciplines and disadvantages early career researchers.
