A mathematics professor at the Institute of Mechanics and Engineering of the University of Bordeaux, in Talence, was indicted in mid-December for allegedly providing information to a foreign power. According to the Paris prosecutor’s office, the researcher is suspected of leading a Chinese delegation into areas designated as highly sensitive.

There is nothing voluntary or intentional on the part of my client.

Lawyer for the accused

The professor, who works in a laboratory on the Talence campus designated as a restrictive regime zone (RZR), was initially questioned in early 2025 following the opening of an investigation in January 2024. His lawyer, Me Gérard Danglade, called the indictment “implausible,” stating his client “does not work with industry.” “He is a mathematician researcher, who has no relationship with industrialists or people who work on secret projects. Given the personality of my client, I do not imagine him being in espionage-type cases,” Danglade added.

While the presence of “foreign students” within the institute is acknowledged by both the professor and his counsel, they deny any violation of access protocols to the RZR laboratory. “There is a very particular protocol for accessing a ZRR,” explained the professor’s lawyer.

Restrictive regime zones in French higher education and research are research units or laboratories with tightly controlled access to prevent espionage. Access is extremely limited, controlled, and requires authorization from the University president, following a favorable opinion from the Ministry of Higher Education.

The University of Bordeaux currently lists 26 ZRRs across approximately ten research units. Authorization requests typically come from doctoral students as part of their research.

Colleagues of the professor on the Talence campus expressed a mix of shock and disbelief. His arrest at the research laboratory was described as a “real shock,” with one colleague reporting “14 hooded police officers” entering the building, leading some to believe there was a terrorist attack, according to Bertrand Lubac, general secretary of the Cgt union at the University of Bordeaux.

These restrictive regime zones are a real attack on public research.

The Cgt union at the University of Bordeaux raised concerns about the impact of restrictive regime zones on research practices. “We work on cooperation, on open relations with the national and international academic world, so these are real barriers that emerge in our research,” Lubac explained, further characterizing the zones as “detrimental for French research.” He emphasized that French research is founded on academic freedom, independent of economic and political pressures, and serves as a “pillar of democracy.”

According to cybersecurity specialists, espionage threats should be taken very seriously.

Cybersecurity professionals emphasize the growing seriousness of espionage threats. “We have more and more cases of espionage and internal threats,” explained Jérémy Voisin, cyber defense director at Cheops Technology. “The easiest way to spy is phishing, or the internal employee who voluntarily or involuntarily engages in risky behavior for the company.” Voisin also cautioned that artificial intelligence raises new questions: “who will use the data we provide, which country is behind it?”

The indicted professor remains under judicial supervision, having been released but barred from accessing his laboratory. If convicted, he faces up to 15 years in prison and a fine of €225,000.
