The 2nd edition of Research.com ranking of the best scientists in the
discipline of Mechanical and Aerospace Engineering is based on data
derived from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected 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
values for an examined discipline.

The focus of our Mechanical and Aerospace Engineering research
Research.com’s best researchers ranking is a trustworthy
lineup of leading scientists from the area of
Mechanical and Aerospace Engineering, based on a meticulous
examination of 166,880 scientists determined
from multiple bibliometric data sources. For the discipline of
Mechanical and Aerospace Engineering, as many as 5741 scholars were
analysed.
What is D-index acceptance threshold for Mechanical and Aerospace Engineering
The D-index threshold for accepting a scientist to be
examined is placed at 30 if
the majority of of their publications are in the field of Mechanical and Aerospace Engineering. The
inclusion criteria for scholars to be
considered into the ranking of top researchers are based on the D-index, proportion
of the contributions made within the given area
plus the awards and achievements of the scholars. The
D-index threshold for considering top scholars is
set as an increment of 10 depending on the overall number of researchers
projected for each scientific field whilst
guaranteeing that the top 1% of best researchers are
added into the list. We expect a proximity of
30% or less between a scholar’s general H-index and their D-index.
Additional verification practices
Since our leading aim is to guarantee that only
actual scholars are listed in
our ranking we realize that metrics are never
meant to be an absolute tool to quantify the
output of scientists. Because of that
we manually inspect each profile and cross-correlate it against publications in a
wide range of credible sources. While it’s not a
factor impacting a researcher’s position in
the ranking, the number of papers published in
major journals and conference proceedings should be a
credible secondary indication of their contribution to research in a
specific field of study. Position in the ranking is
determined by each researcher’s D-index
with the help of data compiled from OpenAlex and
CrossRef, which are the most prominent and well-known bibliometric
databases of this kind accessible to the scientific community. A
detailed explanation of our research process
can be found on our
methodology page.
Our goal
Our objective is to motivate scientists,
businessmen and decision-makers
around the world to explore where leading experts are heading
and to give a way for the entire research community to
find out who the leading experts in specific
areas of study, in various countries, or even within research
institutions are.
