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

The scope of our Engineering and Technology research
Research.com’s best researchers ranking is a reliable
lineup of leading scientists from the field of
Engineering and Technology, based on a detailed
examination of 166,880 scholars identified
from a variety of bibliometric data sources. For the area of
Engineering and Technology, more than 27940 researchers were
investigated.
What is D-index inclusion threshold for Engineering and Technology
The D-index threshold for approving a researcher to be
evaluated is established at 30 if
most of their publications are in the discipline of Engineering and Technology. The
acceptance criteria for scholars to be
considered into the ranking of top researchers are based on the D-index, proportion
of the publications made within the selected area
as well as the awards and achievements of the researchers. The
D-index threshold for listing top scholars is
set as an increment of 10 depending on the overall number of scholars
estimated for each scientific field whilst
guaranteeing that the top 1% of best researchers are
considered into the ranking. We expect a proximity of
30% or less between a scholar’s general H-index and their D-index.
Other verification methods
Since our main aim is to ensure that only
credible researchers are listed in
our ranking we are aware that raw data are never
supposed to be an absolute means to evaluate the
output of scholars. Because of that
we manually check each profile and cross-correlate it against publications in a
wide range of credible sources. Even though it’s not a
factor impacting a scientist’s position in
our ranking, the amount of documents published in
well-known journals and conference proceedings should constitute a
reliable secondary signal of their contribution to research in a
selected field of study. Position in the ranking is
determined by each scholar’s D-index
using information compiled from OpenAlex and
CrossRef, which are the most credible and well-known bibliometric
databases of this kind available to the research community. A
thorough overview of our research policy
can be found on our
methodology page.
Our mission
Our goal is to motivate scholars,
companies and politicians
around the world to investigate where top experts are heading
and to offer a way for the whole scientific community to
discover who the leading experts in specific
disciplines, in different countries, or even within research
institutions are.
