OpenReview PhD cohort analysis
The researcher pipeline is exploding, not just “leaking.”
Top-conference/OpenReview profiles show a much bigger story than one-way brain drain: China is training more AI researchers at home, while return migration appears on a delayed clock.

Denominator effect
The field got much bigger
Snapshot migration ratios can look scary because recent cohorts are huge and many people have not reached a return-or-stay decision point.
Domestic capacity
China can now train at scale
The China-PhD count rises from double digits in early cohorts to hundreds per year in the recent sample.
Brain circulation
Return is delayed, not instant
Older study-abroad cohorts show meaningful returns; younger cohorts are still in postdoc, industry, or first-lab windows.
Sample lens: Chinese-affiliated AI researchers with OpenReview profile histories and publications in ICLR, ICML, or NeurIPS from 2020 to 2025. This is a macro sample, not the same as the hand-curated Atlas people set. Analysis credit: China Research Collective.
