Danhao Wang has been identified by University of Michigan officials as the Chinese postdoctoral research fellow who died two weeks ago, prompting Chinese officials to demand an investigation after claiming the researcher underwent what they called “hostile questioning” by federal law enforcement.
While Chinese officials did not name the researcher, UM Department of Police and Public Safety spokeswoman Melissa Overton identified Danhao Wang as the researcher and said his March 20 death is being investigated as a “possible act of self harm.”
Chinese officials have not named the researcher.
Why did Danhao Wang die?
“On March 19, at approximately 11:00 p.m., officers from the University of Michigan Police Department responded to a report of a subject who fell inside the George G. Brown Building,” UM Police Department spokeswoman Overton said in an emailed statement. “A faculty research assistant was found after falling from an upper level and was later pronounced deceased.”
The complete police case will not be released until the toxicology reports are complete, Overton said.
Who was the University of Michigan Chinese researcher?
Danhao Wang was an electrical and computer engineering research assistant at the University of Michigan.
He listed himself as a postdoctoral research fellow who had been at UM since August 2022, according to Wang’s LinkedIn file.
Before that, Wang spent almost five years at the University of Science and Technology of China ― from September 2017 to July 2022 ― getting a Ph.D. in electrical and electronics engineering, according to his LinkedIn file. He had not posted recently on his LinkedIn account and had two followers.
Wang’s work had appeared 112 times in publications, according to ResearchGate.
What was Danhao Wang’s research focus?
Wang described his research focus this way on ResearchGate, a social networking site developed for scientists and researchers so they can share their work and collaborate:
“My research stands at the intersection of interdisciplinary electrical engineering, material science, chemistry, and photonics/optoelectronics. Specifically, I delve into the exploration, synthesis, and characterization of III-nitride semiconductor thin films and nanostructures, which are crucial for advancing the next generation of electronic and photonic devices.
“Recently, my research scope has broadened to include the study of ferroelectric ScAlN materials and low-dimensional semiconductors.”
What are Chinese government officials saying?
A Chinese Ministry of Foreign Affairs spokesperson claimed the “heartbreaking death” by suicide of a Chinese postdoctoral scholar happened “after being subjected to hostile questioning by U.S. law enforcement personnel” and “calls into question once again the impact and legitimacy of unwarranted U.S. interrogation and harassment targeting Chinese researchers and students.”
Chinese government officials have repeatedly protested such “law enforcement actions” against Chinese researchers, arguing that they “seriously violate Chinese citizens’ lawful rights, poison the atmosphere for people-to-people exchanges between the two countries and continue to create a serious chilling effect,” the Ministry of Foreign Affairs spokesperson said in a statement posted on X.
“China calls on the U.S. to carry out a full investigation, give the family of the victim and the Chinese side a responsible explanation, and stop discriminatory enforcement against Chinese students and scholars in the U.S.”
The Chinese Consulate in Chicago added this comment on X: “For some time now, the U.S. has overstretched the concept of national security for political manipulation and groundlessly interrogated and harassed Chinese students and scholars.”
The FBI hasn’t responded to a Detroit News request for comment.
Why have Trump officials investigated Chinese researchers?
Wang’s death comes over a year into a crackdown by President Donald Trump’s administration on foreign influence at U.S. universities. UM came under particular scrutiny for misreporting the amount of money it received from the Chinese government, and at least five university students from China were charged by federal authorities with smuggling biological material into the U.S. and lying about it.
Six days after Wang’s death, UM interim President Domenico Grasso appeared before the U.S. House Committee on Education and Workforce to address concerns of Chinese espionage occurring within American higher education institutions.
Grasso told members of Congress that the university continues to improve background checks for foreign students and researchers, and has strengthened policies around sensitive material. He reiterated that the university had no knowledge of the alleged crimes committed by Chinese students at the university.
Grasso could not answer how many specific research projects funded by the U.S. government that foreign students were working on when asked by Rep. Elise Stefanik, R-New York. He said foreign students were a crucial part of the university and emphasized the need for continued partnerships between UM and other countries.
“(Foreign students) come and enrich our campuses because they not only bring their intellectual power, but they bring different perspectives from around the world,” Grasso said. “It helps our researchers attack very different problems from different perspectives.
U.S. Rep. Tim Walberg, R-Tipton, the committee chair, said after the hearing he felt the university had taken “significant action” to address federal concerns over foreign influence and espionage.
Five Chinese UM students were charged in October 2024 with crimes including conspiracy, lying to federal investigators and destroying records during a federal investigation after they were found on Camp Grayling, a military facility in northern Michigan, during a U.S. National Guard training exercise with members of the Taiwanese military in 2023.
The criminal case filed by FBI Special Agent Caroline Julee Colpoys said the students were found with cameras near numerous military vehicles, tents and classified communications equipment. The students left the country after graduating in May 2024 before they could be prosecuted.
How do University of Michigan researchers remember Wang?
Dean of Engineering Karen Thole told the university’s College of Electrical and Computer Science staff, faculty and students about Wang’s death in a March 23 email.
“Dr. Wang was a promising and brilliant young mind, whose research into wide bandgap III-nitride semiconductor materials and devices published in Nature stands as a landmark, uncovering for the first time the switching and charge compensation mechanisms of emerging ferroelectric nitrides,” Thole wrote. “His loss is felt deeply not only by those who knew him here at the University, but also everyone who understands his potential to have contributed to breakthroughs in science that would have positively impacted people around the world.”
