@UTDCompSci Quite a surprise that Ding‑Zhu Du is still allowed to teach in 2025 Fall after public sexual harassment & gender discrimination allegations. His computational complexity book is well known for being full of technical mistakes, as pointed out by many famous scholars in theoretical

Ding‑Zhu Du built COCOON after ISAAC 1994. Now he has been removed from the ISAAC Steering Committee and dropped as an Invited Speaker of COCOON 2025. The community is finally acting.👏 Good job, everyone! @UTDCompSci @UTDJonsson @UT_Dallas @UMNews @IEEEorg @ComSoc @NSF @USEEOC.

❗New paper alert: Ding‑Zhu Du co‑authors yet again with his student‑turned‑wife Weili Wu. Is it time for relevant investigations to demand a clear disclosure of their exact contributions? Or are we looking at yet another favorable fake co‑authorship? đŸ€”đŸ€”đŸ€”.@UTDCompSci

Thank you for sharing the origin story of COCOON! But the story didn’t end there: while Weili Wu once showcased photos of Ron Graham with her husband Ding‑Zhu Du from ISAAC 1994 in public talks to project legitimacy, Ron Graham later publicly retracted the award he once gave to

COCOON marked its 30th anniversary last year. And who’s been PC Co‑Chair not once, not twice, but 6 times?👉 Ding‑Zhu Du. Wow~ such amazing coincidence
 or perhaps a lifetime subscription to the chair’s seat? Truly a king! 👑@UTDCompSci @UTDJonsson @UT_Dallas @UMNews @IEEEorg

When Weili Wu is in charge of the conference COCOA, guess who racks up the largest number of publications there?👉 Her own stepson. What a coincidence. Or just another family tradition? đŸ€”@UTDCompSci @UTDJonsson @UT_Dallas @UMNews @IEEEorg @ComSoc @NSF @USEEOC #IEEEFellow

When Ding‑Zhu Du served as the PC Co‑Chair of COCOON 2013, who ended up with the largest number of accepted papers? His own student‑turned‑wife, Weili Wu. @UTDCompSci @UTDJonsson @UT_Dallas @UMNews @IEEEorg @ComSoc @NSF @USEEOC #IEEEFellow #AcademicEthics #AcademicMisconduct

A prayer for our academic world: May those who have caused harm find the wisdom to stop. May Ding‑Zhu Du and Weili Wu awaken to the damage done—to students, to colleagues, to the world, to the future itself. May they cease the harm and choose a path of integrity. May their

All religions speak of hell. Yet at such an age, Ding‑Zhu Du still continues to cause harm, showing no regret for the profound damage he has done to the world, to countless others, and to the future itself

This is no longer about calling out Ding-Zhu Du and Weili Wu—it’s about seeing a systemic wound: Talented researchers blocked, their opportunities stolen; Young students misled to think gift authorship is “normal”; Soil meant to be pure, turned into a marketplace of favors. They.

These unjust acts plant seeds that grow far beyond what Ding-Zhu Du and Weili Wu can see. What seems like just one award or just one paper can leave countless others disheartened—my own department head used that exact word when I reported their academic misconduct—eroding.
