  10. 10 Guohai Situ China · #103,799 worldwide overall 6.6 of 17 papers here in the top 10%

Ranked on their work in Acoustics and Ultrasonics alone: how many more of their papers here reached the world top 10% for their subfield and year than the 10% expected, among 53,856 ranked researchers with a paper here. Each paper counts once, so many strong papers outrank one famous one, and a long record of ordinary papers does not climb. Identities come from OpenAlex author disambiguation, which occasionally merges or splits people.
