Prof. Dr. Rıdvan Kızılkaya, co-founder of Agrobigen and a faculty member of the Department of Soil Science and Plant Nutrition, Faculty of Agriculture, Ondokuz Mayıs University, has been named in the list of the world's most influential scientists, prepared each year by Stanford University in collaboration with Elsevier. This year Prof. Dr. Kızılkaya is included in both the single-year impact and the career-long impact categories, and he has appeared on the list every year for the past four years.
The list is based on publication and citation data from Elsevier's Scopus database. Scientists are assessed across 22 fields and 174 subfields using a composite indicator (c-score) that combines total citations, the h-index, the hm-index and citations to papers as single, first and last author. Scientists ranked in the top 2% of their subfield, or among the top 100,000 worldwide, are included. The single-year category is based on citations received in the most recent year, while the career-long category reflects citations accumulated over an entire academic career.
According to the results announced by Ondokuz Mayıs University on 9 October 2026, Prof. Dr. Kızılkaya is one of six OMU scientists included in both categories.
This scientific expertise in soil science and plant nutrition underpins Agrobigen's R&D and products. On behalf of the Agrobigen family, we congratulate our co-founder on this achievement.
