Stanford University recently released the World’s Top 2% Scientists 2020. Professor Peifeng Li is included in the “Lifetime Scientific Impact List.” The World’s Top 2% Scientists 2020, published by Stanford University in the US, is a list of the top 2% of scientists in the world from among nearly seven million scientists. The list is divided into 22 fields and 176 sub-disciplines, which includes about 160,000 eminent scientists in various fields. The list is divided into two categories: the Lifetime Science Impact Ranking (1960–2019) and the 2019 Science Impact Ranking. The Lifetime Science Impact Ranking (1960–2019) measures the combined impacts of the performance of scientists during their careers.
