FBI raids home of prominent computer scientist who has gone incommunicadoIndiana University quietly removes profile of tenured professor and refuses to say why.A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer, Indiana University, and had his homes raided by the FBI. No one knows why.
Xiaofeng Wang has a long list of prestigious titles. He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering, a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, and a tenured professor at Indiana University at Bloomington. According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.
He has also co-authored scores of academic papers on a diverse range of research fields, including cryptography, systems security, and data privacy, including the protection of human genomic data. I have personally spoken to him on three occasions for articles here, here, and here.
In recent weeks, Wang's email account, phone number, and profile page at the Luddy School were quietly erased by his employer. Over the same time, Indiana University also removed a profile for his wife, Nianli Ma, who was listed as a Lead Systems Analyst and Programmer at the university's Library Technologies division.
As reported by the Bloomingtonian and later the Herald-Times in Bloomington, a small fleet of unmarked cars driven by government agents descended on the Bloomington home of Wang and Ma on Friday. They spent most of the day going in and out of the house and occasionally transferred boxes from their vehicles. TV station WTHR, meanwhile, reported that a second home owned by Wang and Ma and located in Carmel, Indiana, was also searched. The station said that both a resident and an attorney for the resident were on scene during at least part of the search.
Attempts to locate Wang and Ma have so far been unsuccessful. An Indiana University spokesman didn't answer emailed questions asking if the couple was still employed by the university and why their profile pages, email addresses, and phone numbers had been removed. The spokesman provided the contact information for a spokeswoman at the FBI's field office in Indianapolis. In an email, the spokeswoman wrote: "The FBI conducted court authorized law enforcement activity at homes in Bloomington and Carmel Friday. We have no further comment at this time."
Searches of federal court dockets turned up no documents related to Wang, Ma, or any searches of their residences. The FBI spokeswoman didn't answer questions seeking which US district court issued the warrant and when, and whether either Wang or Ma is being detained by authorities. Justice Department representatives didn't return an email seeking the same information. An email sent to a personal email address belonging to Wang went unanswered at the time this post went live. Their resident status (e.g. US citizens or green card holders) is currently unknown.
Fellow researchers took to social media over the weekend to register their concern over the series of events.
"None of this is in any way normal," Matthew Green, a professor specializing in cryptography at Johns Hopkins University, wrote on Mastodon. He continued: "Has anyone been in contact? I hear he’s been missing for two weeks and his students can’t reach him. How does this not get noticed for two weeks???"
