At least ten prominent scientists and researchers have departed the United States and United Kingdom for positions in China and Hong Kong in 2026, citing shrinking research funding, geopolitical friction, and limited opportunities for Chinese-origin academics to lead major projects in the West. The departures span disciplines from semiconductor engineering and artificial intelligence to neurobiology and electric motor design — signalling a broadening talent realignment with significant implications for global science and technology competition.

Who is leaving and why

Zhang Kai, a Yale-affiliated scientist constructing an ultra-large-scale cellular structure group data bank, returned to China, describing the environment in the US as effectively impossible for Chinese researchers to lead projects of that ambition. Chen Peipei, an energy scientist, departed Cambridge University to build her own laboratory in Hong Kong, citing shrinking research funding and a complex geopolitical climate in Britain.

Most strikingly, Omar Yaghi — winner of last year's Nobel Prize for Chemistry — has joined Tsinghua University to lead a new AI-driven research centre, marking one of the highest-profile Western-to-China academic transitions in recent memory. Dai Liang, a physicist awarded a fellowship reserved for the 'brightest young scientists' in the US and Canada for his black hole research, has also returned to a post in Shanghai.

Semiconductor and AI talent on the move

Semiconductor scientist Jiang Jianfeng left MIT for Peking University, becoming a doctoral supervisor just 18 months after earning his PhD — a feat that typically takes eight to ten years. Ling Haibin, the computer scientist credited with creating the world's first mobile plant identification app, left the US to join Westlake University in Hangzhou. An unnamed expert in semiconductor packaging and memory chips departed the University of California, Irvine after more than two decades to join a leading conductive materials company in eastern China.

Life sciences and engineering talent follow suit

Neurobiologist Chih-Ying Su, former faculty vice-chair at the University of California San Diego and celebrated for her olfactory research using fruit flies and mosquitoes, has joined the Shenzhen Academy of Medical Sciences (SMART). Computer vision pioneer Liang Jie, whose work at Microsoft two decades ago was embedded in Windows Media Video Player and Blu-ray technology, has also returned to China.

In engineering, Zhu Ziqiang — described as one of the world's leading experts in electric motor engineering — ended a 38-year career in Britain to take a full-time position at Hong Kong Polytechnic University.

The competitive backdrop

The pattern reflects a structural shift that has been building for years: Western governments have tightened scrutiny of researchers with ties to China under national security frameworks, while simultaneously cutting science budgets. China, meanwhile, has aggressively expanded recruitment programmes and laboratory infrastructure, offering competitive salaries, dedicated facilities, and leadership roles that many researchers say are unavailable to them in the US or UK. Institutions such as Tsinghua University, Peking University, Westlake University, and SMART in Shenzhen are emerging as preferred destinations.

What's next

The cumulative loss of expertise in semiconductors, AI, neuroscience, and clean energy engineering could have long-term consequences for Western technological competitiveness, particularly in sectors already under pressure from the ongoing chip-technology rivalry. Policymakers in Washington and London face mounting pressure to address funding gaps and institutional barriers before the talent drain accelerates further.
