When knowledge and identity converge, even decades abroad cannot dim the call of home.
Two recent cases highlight how the love of one’s homeland continues to inspire world-class scientists to return after long careers abroad.
Liu Jun, a celebrated statistician and member of the U.S. National Academy of Sciences, chose to leave Harvard after 25 years to join Tsinghua University’s newly established Department of Statistics and Data Science. For him, the decision was rooted in academic ambition with a deep sense of patriotism and a desire to nurture young talent in China. Having grown up in the final years of the Cultural Revolution, when even pursuing mathematics was a struggle, Liu sees his return as a way of giving back to a nation that has undergone profound transformation since his youth.
Similarly, Zhongwei Shen, a pioneering mathematician who spent nearly four decades in the United States, most of them at the University of Kentucky, accepted a chair professorship at Westlake University in Hangzhou. Shen, long committed to bridging China and the West through research, described the move as an opportunity to contribute directly to China’s rapidly expanding scientific ecosystem. For him, the chance to engage again with undergraduates, to feel their curiosity and enthusiasm, was equally important. His return was not a sudden choice but the result of years of reflection and continued ties with Chinese academia.
The two cases reflect more than personal decisions; they embody a wider trend in global science. With China investing heavily in higher education, research infrastructure, and cross-disciplinary collaboration, it is increasingly able to attract back talent once assumed lost to the West. This shift boosts China’s scientific capacity and signals a rebalancing of intellectual flows that for decades favored Western institutions.
At the heart of these stories lies a powerful reminder: the motivations of scientists are not purely professional. Beyond publications and laboratories, there is often a deeper connection, a sense of belonging, identity, and responsibility toward the next generation. Liu Jun and Zhongwei Shen remind us that the love of the motherland can be as strong a force as any grant or accolade, shaping the direction of lives and, in turn, the future of science.
