Who are the most influential thinkers in world?

Identify leaders in your chosen discipline, research top professors in your area of study, and search for schools based on the luminaries who most inspire you!

Note: These rankings change dynamically as our artificial intelligence system learns new things and incorporates new publications and citations. Academics are constantly doing research and publishing new insights, with the result that our measure of influence is subject to continual adjustments. For quality assurance reasons, however, we forgo real-time changes, with most public updates happening only quarterly. In any case, don’t be surprised to see our rankings change over time.
