Best Engineering and Technology Scientists in Japan

The 1st edition of Research.com ranking of top Engineering and Technology scientists is based on data collected from Microsoft Academic Graph on December 6th, 2021. Position in the ranking is based on a scientist's D-index (Discipline H-index), which only includes papers and citation values for an examined discipline. Show more

Our best scientists ranking is a reliable list of leading scientists from the area of Engineering and Technology, based on a meticulous examination of 166,880 scientists on Microsoft Academic Graph. For the discipline of Engineering and Technology, over 17,156 profiles were examined.

The D-index threshold for approving a scholar to be considered is set to 30 if most of their publications are in the field of Engineering and Technology. The inclusion criteria for scholars to be considered into the ranking of top scientists are based on the D-index, proportion of the contributions made within the given discipline in addition to the awards and achievements of the scientists. The D-index threshold for listing top scientists is set as an increment of 10 depending on the total number of researchers estimated for each discipline whilst ensuring that the top 1% of leading scientists are considered into the ranking. There should be a proximity of 30% or less between a scientist's general H-index and their D-index.

Because the main goal is to ensure that only genuine researchers are included in the ranking we believe that numbers are never meant to be an absolute measure to quantify the contributions of scientists. This is why we manually verify each profile and cross-correlate it against publications in a wide range of credible sources. Even though it’s not a metric defining a scientist’s position in the ranking, the amount of documents published in major journals and conference proceedings should constitute a reliable secondary indication of their contribution to research in a given discipline. Position in the ranking is based on each scientist’s D-index using data compiled from Microsoft Graph, which is the most prominent and well-established bibliometric database of this type available to the scientific community. A detailed definition of our research process can be found on our methodology page .

Our aim is to inspire scholars, entrepreneurs, and decision-makers worldwide to explore where leading experts are heading and to provide an opportunity for the entire scientific community to discover who the leading experts in specific fields of research, in different countries, or even within research institutions are.
