Highly Cited Researchers 51 Scientists Citation Rankings - 2025

Discover the world’s highly cited researchers through the AD Scientific Index 2025 Citation Rankings.
These rankings evaluate scientists based on their total and recent citation counts, capturing the breadth and real-time currency of academic recognition. Citation data reveals how widely a scholar’s work is referenced, applied, and extended across diverse disciplines. The rankings are routinely updated to reflect ongoing citation growth, while eliminating distortions from excessive co-authorship and institutional inflation. Premium tools provide access to detailed citation dynamics, unethical citation behavior detection, and field-normalized benchmarking.
