Professor Kenichiro Hayashi, a plant scientist in the Department of Bioscience at Okayama University of Science (OUS) in Japan, has been included among the world's top 2% of scientists for the sixth consecutive year, according to the latest update of a standardized citation-based scientist database developed by researchers at Stanford University and published by Elsevier.
The latest database, released on October 7, includes Hayashi in both the single-year category, based on citation indicators for 2025, and the career-long category, which assesses citation impact over a scientist's career. He has appeared in both categories for six consecutive years.
The database draws on research publications indexed in Elsevier's Scopus abstract and citation database. It evaluates scientists with at least five published papers across 20 scientific fields and 174 subfields, using standardized citation indicators, including total citation counts, to identify researchers in the top 2%.
Reflecting on his sixth consecutive inclusion, Hayashi said, "I hope to continue enjoying the excitement of science together with my students."
