The 2nd edition of Research.com ranking of the best scholars in the
field of Chemistry is based on data
consolidated from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a scholar’s
D-index (Discipline H-index), which takes into account only
papers and citation data for an examined discipline.

The focus of our Chemistry research
Research.com’s best scholars ranking is a credible
lineup of leading scholars from the area of
Chemistry, created using a meticulous
analysis of 166,880 scientists discovered
from multiple bibliometric data sources. For the field of
Chemistry, over 43178 scientists were
investigated.
What is D-index acceptance threshold for Chemistry
The D-index threshold for including a researcher to be
examined is placed at 40 if
the majority of of their publications are in the field of Chemistry. The
approval criteria for scientists to be
considered into the ranking of top researchers are based on the D-index,
proportion of the publications made within the specific
field of study plus the awards and achievements of the
scholars. The D-index threshold for including top
scientists is set as an increment of 10 depending on the overall number of
scientists estimated for each
discipline whilst making sure that the top 1% of
best researchers are added into the ranking.
We expect a proximity of 30% or less between a researcher’s
general H-index and their D-index.
Additional verification methods
Since our main mission is to ensure that only
credible researchers are listed in
our ranking we believe that raw data are never
supposed to be a complete tool to evaluate the
work of researchers. This is why
we manually verify every profile and cross-correlate it against publications in a
wide range of reliable sources. While it’s not a
element contributing to a researcher’s position in
our ranking, the quantity of documents published in
well-known journals and conference proceedings should be a
reliable secondary indication of their contribution to research in a
given area of science. Position in the ranking is
established using every researcher’s D-index
according to metrics gathered from OpenAlex and
CrossRef, which are the most prominent and well-known bibliometric
databases of this type accessible to the scientific community. A
comprehensive explanation of our research process
can be found on our
methodology page.
Our agenda
Our goal is to inspire researchers,
businessmen and decision-makers
around the world to explore where top experts are heading
and to offer a way for the whole scientific community to
get to know who the leading experts in specific
disciplines, in different countries, or even within research
institutions are.
