9 million researchers, and how they got here.
We’d rather show you the rules than ask you to trust a big number. Here’s who’s in, who isn’t, and where every piece of evidence comes from.
Count researchers by topic
8,345 researchers work on cryo-EM.
Real counts from the GeekScope index, as of . Names and emails are in the product.
Who’s in
Someone gets into GeekScope when they meet one of these:
10 or more published papers. That covers 7,093,945 people, 78% of the index.
Corresponding author on a paper since 2021, meaning they led the work and fielded the questions about it. Most of the remaining researchers come in this way.
An investigator on a grant or a clinical trial.
Not in: people with fewer than 10 papers who haven’t led a paper since 2021. It’s mostly students, early-career researchers and occasional co-authors: real researchers, but rarely the person who signs off on a purchase order.
