University researchers and administrators working in high-risk areas such as engineering and natural sciences need to remain sensitive to the requirements of export controls and to the high personal liabilities that they face for non-compliance.
Governments, universities and individual academics should urgently revisit export-control compliance in academia.
Western governments are tightening export controls to safeguard military and industrial advantages amid rising geostrategic uncertainty. Western universities are thus increasingly forced to reconcile their dual roles as producers of tightly controlled research and development on one hand and as hubs of global knowledge exchange on the other.
A series of breaches over the past two decades has illustrated universities’ challenges. In one striking incident beginning in 2006, senior US academic John Reece Roth received a four-year prison sentence simply for emailing a draft conference paper to an overseas colleague. This case demonstrates how routine academic activities can trigger severe legal and financial penalties.
Universities should also equip themselves to monitor activities that are far from routine. In 2024, the United States Department of Justice disrupted an organised smuggling ring involving University of Florida staff and students. The operation facilitated the illicit shipping of thousands of controlled drug and toxin samples to China.
Clear guidance, strong internal processes and better awareness among researchers will be essential for universities in managing the complex and high-stakes requirements of export controls. Two widely publicised cases drawn from an article I co-authored earlier this year illustrate the practical challenges universities face in ensuring export-control compliance.
The first is a 2013 case involving a Chinese national and then graduate microbiology student at Iowa State University, Wentong Cai. He reportedly conspired with his cousin, Chinese national Bo Cai, to illicitly export military-grade sensors to China. Wentong reportedly used his university-issued email and letterhead to contact an Albuquerque-based supplier of the sensors under the pretence that they were to be used in his work at the university’s laboratories. Wentong and Bo then travelled to New Mexico to meet with the supplier, at which time they received a sensor that Bo intended to smuggle back to China.
Unbeknown to Wentong and Bo, the Albuquerque-based supplier was an undercover US immigration and customs enforcement agent and had given them a non-functioning sensor. About a week after their meeting, Bo was arrested at a Los Angeles airport with the imitation sensor hidden in a computer speaker in his luggage. Bo and Wentong were imprisoned for 24 and 18 months, respectively, after which both were deported.
The second example is the Roth case, mentioned above. In 2006, Roth, a world-renowned American plasma physicist and then professor at the University of Tennessee, travelled to China to deliver a series of lectures. During this time, Roth intended to submit a paper to the 2007 conference of the American Institute of Aeronautics and Astronautics. However, poor hotel wi-fi meant that he could not access the latest draft of the paper. With the deadline fast approaching, Roth urgently contacted one of his PhD students in Tennessee, requesting that the student email the draft paper to Roth’s host in China, a physics professor at Fudan University. The student obliged. Roth’s Chinese host was able to get him a copy of the draft paper with enough time to complete the submission to the conference.
Pages 10 to 14 of the draft paper, however, included data from a project on plasma actuators that was funded by the US Air Force, which fell under export controls. The US District Court for the Eastern District of Tennessee judged that, by instructing his student to forward export-controlled data to a Chinese national without a license, Roth had engaged in the ‘unlawful export of technical data’. This led to a 48-month prison sentence for Roth, which began in January 2012. Roth’s paper was ultimately withdrawn from the conference.
These case studies, though brief, offer a window into the challenges facing university regulators when it comes to export-control compliance.
Roth’s case demonstrates that export-control violations can occur without any apparent premeditation or malice; they can involve intangible goods, such as technical data in email attachments, the distribution of which is difficult to monitor and control; and they can occur through innocuous and routine activities, such as sharing publications or drafts with peers. The Cai case shows that these violations can occur outside formal university structures through the independent and unsanctioned actions of university actors.
University researchers and administrators working in high-risk areas such as engineering and natural sciences need to remain sensitive to the requirements of export controls and to the high personal liabilities that they face for non-compliance, such as fines and the loss of professional opportunities. In extreme cases, those who commit export-control violations can face deportation and even jail time.
Universities should be clear-eyed about the need to negotiate trade-offs between research security and international engagement. National export-control authorities also need to provide adequate guidance and support to university institutions and researchers navigating increasingly onerous export-control regimes.
