Reshaping global scientific leadership
A quiet but powerful shift is reshaping global scientific leadership: thousands of Chinese scientists are leaving the U.S. and returning home, transforming Science, Technology, Engineering and Mathematics (STEM) research, artificial intelligence (AI), and biotechnology worldwide.
Historically, the United States has been a beacon for scientific talent, drawing in researchers from around the globe, including a large number who hail from China. These scientists have played a pivotal role in advancing U.S. innovation, contributing extensively to cutting-edge research and critical sectors like defense and technology.
However, in recent years, a notable trend has emerged where many of these scientists have begun to return to China. This movement, often termed a ‘reverse brain drain,’ is not just a simple migration; it reflects deeper geopolitical tensions, U.S.-China trade disputes, and scientific collaboration challenges affecting STEM research, national security, and high-tech industries worldwide. While it might seem like a routine exchange of talent, the ramifications are potentially vast, affecting both nations’ scientific prowess and global technological leadership.
Profile of 10 scientists who’ve left US & UK for China so far this year
Only half way through 2026, aleady dozens of Chinese scientists and experts have left the United States and Britain to pursue their careers in China, citing several reasons including insufficient funding and a lack of opportunities for Chinese academics to lead projects in the West.
The South China Morning Post (SCMP) recently put together a list of 10 of these scientists whose stories resonated with its readers. That list is reproduced below.
1. ‘Impossible for Chinese’: Yale scientist Zhang Kai leaves US for China
For Zhang Kai, a pioneering scientist who is building an ultra-large-scale cellular structure group data bank with unprecedented precision, returning home to China was the natural choice to fulfil his ambition.
2. Energy scientist Chen Peipei leaves Cambridge to build her own lab in Hong Kong
For some early-career scientists, the prestige of British academia is being marred by shrinking research funding and a complex geopolitical climate, prompting top-tier talent to look elsewhere for stability and resources.
3. Nobel-winning scientist Omar Yaghi joins China’s Tsinghua University from the US
Omar Yaghi, the winner of last year’s Nobel Prize for chemistry, has joined China’s Tsinghua University to lead a new AI-driven research centre.
4. Chinese black hole-hunting scientist Dai Liang quits US for Shanghai post
A physicist who was awarded a fellowship reserved for the “brightest young scientists” in the US and Canada for his work hunting for black holes has returned to China.
5. Rising star chip scientist Jiang Jianfeng leaves MIT for Peking University
Most academics take eight to 10 years after earning a PhD to become doctoral supervisors. But semiconductor scientist Jiang Jianfeng has done it in just 18 months. Jiang Jianfeng says the decision to return to his home country is a “natural choice”.
6. Noted neurobiologist and ex-taekwondo captain Chih-Ying Su leaves US for China
Celebrated neurobiologist Chih-Ying Su, who specialises in research on the sense of smell using fruit flies and mosquitoes, has left her position as faculty vice-chair at the University of California San Diego to join the Shenzhen Academy of Medical Sciences (SMART).
7. AI scientist Ling Haibin, father of first plant ID app, leaves US for China
AI scientist Ling Haibin, the acclaimed computer scientist behind the world’s first mobile plant identification app, has left his position in the United States to take up a full-time role at Westlake University in Hangzhou, eastern China.
8. North America’s top computer vision scientist Liang Jie returns to China
Twenty years ago, technologies developed by Liang Jie at Microsoft were incorporated into products like the Windows Media Video Player and Blu-ray discs used by millions worldwide.
9. Award-winning memory chip expert leaves US for job at Chinese semiconductor firm
An expert on semiconductor packaging and memory chips has left the University of California, Irvine after more than two decades to join a leading conductive materials company in eastern China.
10. World-leading EV motor expert joins Hong Kong PolyU after 38 years in Britain
Zhu Ziqiang, one of the world’s leading experts in electric motor engineering, has left his four-decade career in Britain to take up a full-time position at Hong Kong Polytechnic University.
Implications for global science leadership
The departure, in large numbers, of scientists of Chinese descent marks more than just a loss to the the United States’ of individual talent – it signals a shift with far-reaching implications for U.S. scientific talent pipeline,
research competitiveness, national security policies, and the future of global leadership in AI, 5G technology, and biomedical research.
