🎥🔦 Coincidence?
Derous falsely portrayed herself as a cyberstalking victim when I exposed her research misconduct; @aomconnect.bsky.social security assaulted and injured me — then told police I was a “stalker.”
Where did the false AOM info come from? I was investigating a Derous paper.⚖️
9/
There’s finally movement:
The Erasmus University CWI is now investigating Derous et al. (2009, 2015) on discrimination and RMSEA falsification.
The Flemish CWI has taken on the Dutry et al. paper Ghent CWI cleared but without actually looking at the scientific issues.
8/
I’ll continue my duty as a whistleblower.
The evidence of misconduct is undeniable — yet Ghent University’s integrity committee refuses to investigate.
Censorship must never replace truth and accountability in science. ⚖️📚
7/
It didn’t end there.
Coincidence — or did the false claim spread?
In Copenhagen, AOM security assaulted and injured me, then told police I was a “stalker.”
The same false narrative, now weaponized across borders?? ⚖️
6/
I was detained twice in holding cells (once overnight) — never heard by a judge, never allowed to show evidence.
Only brief talks with police who mostly shrugged.
This violates academic freedom, due process, and every principle of justice.
5/
Then came the twist: Derous declared herself a cyberstalking victim.
All I did was document her misconduct and contact her professionally by email, as required by ethics codes.
4/
After being pushed out of Ghent University through her and Johnny Fontaine’s misconduct, I continued my duty as a whistleblower — uncovering falsification and fraud in at least two of her papers:

3/
She even insisted on joining my department — only to file yet another complaint.
Result: the department was dissolved, leaving me without affiliation.
In 2022, I reported her misuse of the title “psychologist,” but the Belgian Psychology Commission refused to act.
2/
Prof. Derous has a long record of ethical transgressions.
As I show in my paper Science Eroded ⤵️
📄 www.jonaslang.info/userdata/sci...
She systematically undermined my position at Ghent University through false complaints and retaliation.

1/
When research misconduct gets shielded by false claims of stalking and victimhood.

This is the ⚡shocking story of Prof. Eva Derous (Ghent University, @erasmusuni.bsky.social ) — and how Belgium’s justice system has been misused against a whistleblower. ⚖️

My request asks police to investigate under Straffeloven §163 (false info to authorities), preserve call logs, CCTV & bodycam footage, and recognise me as forurettet (injured party).
False exclusions shouldn’t override lawful registration. 🔦

That statement was untrue — and it misled police, resulting in my removal and also possibly my brief preventive detention. The official Sagsudskrift 0100-20210-00774-25 confirms the false claim shaped the response.
1/
📝 I’ve filed a formal request with the Copenhagen Police to investigate false information given during the Academy of Management conference (Bella Center, July 25 2025).

I was fully registered and paid, yet staff falsely claimed I’d been “excluded 2½ years ago.” ⚖️

🎥🐍 Zijlstra–Hülsheger PhD Grab Case II
Another PhD, same pattern: Emails show pressure, false credit, and the supervisor who did most of the work (me) omitted. Rewarded when Zijlstra got EAWOP’s “Lifetime Contribution Award” as I was assaulted outside in Prague.

I’ve asked the Copenhagen Police – Juridisk Afdeling to investigate:
• False information (§163)
• Assault (§244)
• Unlawful deprivation of liberty (§260)
I also declared myself forurettet (victim) and requested damages.

Medical evidence:
🔹 Ribcage injuries
🔹 Light concussion
🔹 Radiology-confirmed wrist/arm injury
I needed physiotherapy for weeks.
The case was later closed under §749(1) — no charges against me.
2/
Two AOM-hired security guards falsely called me a “stalker” and jumped on my rib cage until police arrived. I was handcuffed and briefly detained despite doing nothing illegal.

⚖️ Investigation Request Filed with Copenhagen Police about the Kunsthal Charlottenborg attack on 27 July 2025.

I’ve now requested a formal investigation into false reporting and unlawful use of force at the Academy of Management ( @aomconnect.bsky.social ) conference in Copenhagen.
11/
So who called me a “stalker”?
Who had motive and timing to benefit from that claim and what happened?
A disturbing chain of coincidences indeed. ⚖️

There was also a lead-up: two months earlier at EAWOP Prague 2025, I was assaulted by security.
Derous sits on the EAWOP Executive Committee.
Their claim? I’d violated a “code of conduct.”
9/
The first author discussed the striking overlaps with master’s theses I supervised with me on instagram. The next day — when her presentation happened — I was in the hospital with serious injuries.
8/
Then Copenhagen: at AOM 2025 a paper overlapping with my prior supervision work was on the program.
Derous was listed as last author — then both her name and the paper vanished from the schedule. Cover-up?
7/
Early 2025 — Derous filed a Belgian police complaint claiming I was “cyberstalking” her for reporting documented/published misconduct online. All I did was document her misconduct and contact her professionally through email, as required by ethics codes. No evidence. No hearing.
6/
Over the years I filed several complaints about Derous: misuse of the psychologist title in Belgium, copying my research ideas without credit, and questionable statistics in several papers. Some were ongoing at the time and discussed in July 2025. Since then new ones have been registered.
5/
Prof. Eva Derous — former colleague (and briefly my supervisee) at Ghent University. I’d reported multiple issues with her conduct.
Her retaliatory complaints helped push me out of my job.
