Chuck Darwin<p>A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity <br>💥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. <br>⚠️ No one knows why.<br><a href="https://c.im/tags/Xiaofeng" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Xiaofeng</span></a> <a href="https://c.im/tags/Wang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Wang</span></a> has a long list of prestigious titles. <br>He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering, <br>a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, <br>and a tenured professor at Indiana University at Bloomington. <br>According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.</p><p>He has also co-authored scores of academic papers on a diverse range of research fields, <br>including cryptography, systems security, and data privacy, including the protection of human genomic data. <br>In recent weeks, Wang's email account, phone number, and profile page at the Luddy School were quietly erased by his employer. <br>Over the same time, Indiana University also removed a profile for his wife, <a href="https://c.im/tags/Nianli" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nianli</span></a> <a href="https://c.im/tags/Ma" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Ma</span></a>, who was listed as a Lead Systems Analyst and Programmer at the university's Library Technologies division</p><p>🔥“None of this is in any way normal” Matthew Green, <br>a professor specializing in cryptography at Johns Hopkins University, wrote on Mastodon. </p><p>He continued: <br>"Has anyone been in contact? I hear he’s been missing for two weeks and his students can’t reach him. <br>How does this not get noticed for two weeks???"</p><p>In the same thread, Matt Blaze, <br>a McDevitt professor of computer science and law at Georgetown University, said: <br>"It's hard to imagine what reason there could be for the university to scrub its website as if he never worked there. <br>And while there's a process for removing tenured faculty, it takes more than an afternoon to do it."</p><p>Local news outlets reported the agents spent several hours moving boxes in an out of the residences. </p><p><a href="https://arstechnica.com/security/2025/03/computer-scientist-goes-silent-after-fbi-raid-and-purging-from-university-website/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">arstechnica.com/security/2025/</span><span class="invisible">03/computer-scientist-goes-silent-after-fbi-raid-and-purging-from-university-website/</span></a></p>
