More than a dozen high-profile Chinese scientists have left US institutions for top roles in China in 2026, according to Times Higher Education. The exodus is driven by a more hostile US policy environment and larger Chinese research budgets. A Stanford study found the number of Chinese scholars returning home rose from 31 in 2004 to 1,409 in 2022.

Key Facts

The number of Chinese scientists returning home rose from 31 in 2004 to 1,409 in 2022, according to a Stanford Center on China's Economy and Institutions study of 1.2 million scholars.
In 2026, more than a dozen very high-profile Chinese scientists have left prestigious US roles for top jobs in China.
Chen Ye, a semiconductor quality control expert with nearly two decades in industry, was appointed Qiushi distinguished professor at Zhejiang University's College of Integrated Circuits.
A Carnegie Endowment study of 100 Chinese-origin top AI researchers at US institutions in 2019 found 87 still at US institutions in 2025, while 10 had left for Chinese companies or universities.

Returning Scholars

Chinese researchers are returning home in growing numbers, driven by a mix of push and pull factors including a more hostile US foreign policy and larger research budgets in China. The trend has been accelerating since the 2010s, coinciding with intensifying technological and scientific rivalries between the US and China. Returnee academics are often among the strongest performers in research, according to Times Higher Education. Chen Ye, a semiconductor quality control expert, is the latest example, having just been appointed a Qiushi distinguished professor at Zhejiang University.

Research Findings

A Stanford Center on China's Economy and Institutions paper analysed the scientific output of 1.2 million scholars between 2003 and 2022. The study found the number of scientists journeying home to China shot up from 31 in 2004 to 1,409 in 2022. The authors defined a returnee as an ethnically Chinese scientist whose affiliation shifts from overseas to China. A Carnegie Endowment for International Peace study published at the end of last year looked at 100 Chinese-origin top AI researchers at US institutions in 2019. It found 87 of them were still at US institutions in 2025, while only 10 had left for Chinese companies or universities and the remaining three moved to other countries.

Strategic Concerns

Lizzi Lee, a fellow on the Chinese economy at the Asia Society Policy Institute's Center for China Analysis, described the trend of Chinese scholars returning home as troubling. She said tacit knowledge, such as identifying the most useful research questions, moves with the researcher and is a strategic worry. Lee added that a second-order problem may ultimately be larger than the departures: the shrinking of the talent pipeline. If fewer top Chinese students come to the US for PhDs, fewer stay for postdocs, and faculty become less funded, the US loses not just top talents today but a large part of the mechanism through which it has historically replenished its scientific pipeline.
