The AD Scientific Index (Alper-Doger Scientific Index) is a ranking and analysis system based on the scientific performance and the added value of the scientific productivity of individual scientists. The AD Scientific Index "World Scientist and University Rankings" has a unique methodology that includes the most useful academic analysis for you, your institution, your country and your subject that you will not find elsewhere. The AD Scientific Index is the first and only study to show the total and six-year productivity coefficients of scientists based on h-index and i10 index scores and Google Scholar citations.
