Academic Fraud Exposed at Top Chinese Universities

A former PhD student turned science blogger has triggered one of China’s most significant academic integrity scandals in recent years, publicly reporting at least five high-profile scholars across multiple elite universities for suspected paper fabrication in top international journals including Nature. The revelations have prompted official investigations, resulted in a dean’s dismissal, and ignited a national debate about systemic failures in China’s academic evaluation system.

The Whistleblower and His Campaign

Geng Hongwei, known online as “Geng Tongxue Jiang Gushi” (“Classmate Geng Tells Stories”), is a former PhD student at Beihang University’s School of Biological and Medical Engineering who dropped out in 2025 to become a full-time anti-fraud blogger. With 1.8 million followers, Geng has built a reputation for meticulously analyzing published research for signs of data fabrication. Since April 2026, he has publicly reported scholars from Tongji University, Nankai University, Sun Yat-sen University, and Shanghai University — all holding prestigious titles such as “Changjiang Scholar,” “National Outstanding Youth Science Fund” recipient, or dean-level administrative positions.

According to Xinhua News, Geng described the fabrication methods as so crude that “they didn’t even use a random number generator.” In one case, he pointed out that a column of data all ended in the digit 5, two columns differed by exactly 0.3, and decimal places were applied inconsistently — patterns that are impossible in genuine experimental data.

Tongji University: The First Case Resolved

The first and most prominent case involves Professor Wang Ping, a National Outstanding Youth Science Fund recipient, Ministry of Education “Changjiang Scholar” Distinguished Professor, and former Dean of Tongji University’s School of Life Sciences and Technology. Wang’s team published a paper titled “Human HDAC6 senses valine abundancy to regulate DNA damage” in Nature in January 2025, proposing a novel cancer treatment strategy involving a valine-restricted diet combined with DNA repair enzyme inhibitors.

In April 2026, Geng publicly reported the paper for systematic data fabrication. Tongji University launched an investigation, and on May 6, the university issued a formal statement confirming academic misconduct. The investigation found that of 14 questioned figures and tables, 10 involved academic misconduct in immunofluorescence staining experiments where cell counts were not objectively performed. One figure involved a mouse weight with an irregular trailing digit, and three figures involved duplicated images.

Wang was removed as dean, demoted two levels in professional technical rank, and disqualified from position appointments, salary increases, promotions, research project applications, and awards for 24 months. The first author, Jin Jiali, had her employment relationship with Tongji’s Advanced Research Institute terminated.

A Spreading Crisis: Nankai, Sun Yat-sen, and Shanghai Universities

Following the Tongji case, Geng turned his attention to other institutions. On April 25, he questioned Dean Chen of Nankai University’s School of Life Sciences over data anomalies in a Nature Cancer paper. Nankai announced an investigation on May 1.

At Sun Yat-sen University, two scholars have been reported: Vice Dean Kuang of the School of Life Sciences, and Deputy Director Kang of the Cancer Prevention Center, a National Outstanding Youth Science Fund recipient reported on May 4 for data fabrication in a Nature sub-journal. Both cases are under investigation.

Shanghai University’s Dean Su Jiacan of the Translational Medicine College was also reported for Nature sub-journal data fabrication. The university has established an investigation team and emphasized a policy of “zero tolerance.”

Systemic Failures Exposed

The scandal has laid bare deep-rooted problems in China’s academic system. Researchers interviewed by Xinhua identified several key issues:

The “name-sharing” culture (挂名): Senior academics attach their names to work they did not supervise. As one researcher told Xinhua, “The bigger the ‘big shot,’ the easier it is to lose oversight of the authenticity and reliability of papers. They’re too busy; they might not even know exactly what their subordinates are doing.”

Weak institutional oversight: A researcher at a national research institution described how research offices “mostly only serve a ‘record-keeping’ function, not substantive review. Academic integrity mainly relies on the self-discipline of the research group.”

Quantity-over-quality evaluation: Universities incentivize top-journal publications for rankings and funding, creating perverse incentives. Multiple interviewees noted that many institutions lack the motivation to proactively investigate misconduct because high publication counts benefit institutional rankings.

Low cost of fraud: The benefits of publishing in top journals — including prestigious “hats” (帽子), administrative promotions, and significant research funding — far outweigh the risks of detection and punishment.

Broader Implications and Reform Efforts

The case has raised urgent questions about the effectiveness of China’s academic integrity mechanisms. The disputed Tongji paper had been questioned on PubPeer as early as June 2025, with researchers pointing out image duplication and suspicious data patterns — yet no action was taken until Geng’s public exposure.

Nature Editor-in-Chief for Biological, Clinical and Social Sciences, Francesca Cesari, stated on April 22 that the journal had noted the criticisms and was evaluating them through established editorial processes. Meanwhile, Geng has submitted evidence through the National Natural Science Foundation of China’s (NSFC) official reporting portal, raising the possibility that the NSFC could demand repayment of research funds from those found guilty of fraud.

China has introduced multiple policy documents in recent years aimed at strengthening academic integrity, including the “Rules for Investigating Scientific Research Misconduct” and Ministry of Education guidelines on research诚信 (integrity) construction. However, implementation has been inconsistent.

What’s Next

Beijing scholar told Xinhua that Tongji’s investigation speed and punishment severity “can hopefully set an example” for other universities yet to announce their findings. Experts are calling for faster resolution of cases, the use of AI for data screening in peer review, and a fundamental shift in evaluation systems away from what they describe as a “digital competition” of publications.

As one online comment cited by Hong Kong’s Ming Pao noted: “If they get off lightly, it means collective fraud to scam state funding can continue. If not, heads will roll.” The outcomes of the investigations at Nankai, Sun Yat-sen, and Shanghai Universities — and whether Nature ultimately retracts the disputed paper — will be closely watched as indicators of whether China’s latest integrity drive will produce lasting change.
