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. ... 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???" In the same thread, Matt Blaze, a McDevitt professor of computer science and law at Georgetown University, said: "It's hard to imagine what reason there could be for the university to scrub its website as if he never worked there. And while there's a process for removing tenured faculty, it takes more than an afternoon to do it."
