Shenzhen, China — A former chair of Harvard University’s chemistry department, convicted in the United States for concealing ties to Chinese talent programs, has resurfaced in China as the leader of a state-backed institute focused on advanced brain-computer interfaces (BCI). The move has raised fresh concerns about technology transfer and its potential military applications.
Charles Lieber, 67, a pioneering researcher in nanoscience and neural interfaces, was convicted in 2021 on charges of making false statements to federal authorities about his participation in China’s Thousand Talents Program and related tax offenses. He served a minimal sentence of two days in prison, followed by six months of house arrest, and paid fines and restitution.
In April 2025, Lieber relocated to Shenzhen. He now serves as the founding director of the Institute for Brain Research, Advanced Interfaces and Neurotechnologies (i-BRAIN), an arm of the Shenzhen Medical Academy of Research and Translation (SMART). The institute provides him with advanced nanofabrication equipment, primate research facilities, and substantial government funding aligned with China’s national priorities in neurotechnology.
Lieber’s work centers on embedding nanoscale electronics into brain tissue. This technology holds promise for medical breakthroughs, including treatments for paralysis, ALS, and other neurological conditions. However, it also carries dual-use potential. According to U.S. Defense Department assessments, China’s People’s Liberation Army has explored brain interfaces to enhance soldiers’ cognitive abilities, situational awareness, and overall performance — capabilities sometimes described in broader discussions as steps toward “super soldiers.”
The development comes amid intensifying U.S.-China competition in artificial intelligence, biotechnology, and human-machine integration. Analysts note that Lieber’s relocation highlights limitations in current U.S. safeguards designed to protect sensitive research with military applications. He reportedly brought at least one other Harvard researcher, Jung Min Lee, an expert in stitching electronics into brain tissue, to join him at i-BRAIN.
In a December 2025 Shenzhen government conference, Lieber reportedly remarked that he arrived in China in April 2025 “with a dream and not much more, maybe a couple bags of clothes.” His new role places him at the forefront of a field Beijing views as strategically vital.
The case has drawn renewed attention to the challenges of retaining top scientific talent in the United States and the aggressive recruitment efforts by China. While Lieber’s research has legitimate civilian applications, its potential to bolster military capabilities underscores ongoing national security debates surrounding dual-use technologies.
