Citation Rankings highlight the world’s Highly Cited Researchers based on total and recent 5-year citation counts. These rankings reveal how widely and consistently a researcher’s work is cited, reflecting their level of scientific influence. Data is analyzed using near real-time metrics, with special attention to unethical practices and manipulative behaviors. To ensure transparency and data integrity, the reporting of potential violations is actively encouraged. Comparative analysis is available across 13 main fields and 221 academic disciplines. This ranking is unique to the AD Scientific Index.
