Inspector Voinnet, Wollman in fraud-overdrive, and Farewell to Jessus

Catherine Jessus resigned, Olivier Voinnet solves the crime he was suspected of, and their mutual investigator Francis-Andre Wollman might want to investigate his own papers

In Spain, the giant of cancer and ageing research, Carlos Lopez-Otin has fallen over the many data manipulations in his papers, while an anti-scientific uprising of corrupt politicians and crooked academic elites decries my ETA-like terrorist conspiracy against a martyr saint, fed by fascistoid press calling for the heads of falsely accused scapegoats at his University of Oviedo. Lopez-Otin recently destroyed all his transgenic mice, allegedly over an infection, and now raves from his Paris exile about the injustices he as a scientist with h-index of 100 gets to endure.

In France, also in Paris, another Jesus figure recently also fell over similarly Photoshopped data, despite massive support from her peers: the developmental biologist Catherine Jessus resigned on February 1st as director of CNRS biology branch INSB, replaced by Ande Le Bivic and now remains merely a humble Sorbonne University professor. At the same time, another alleged victim of injustice and conspiracy, the French plant biologist Olivier Voinnet, exiled to ETH Zürich, found guilty of fraud, tainted with 8 retractions and over 20 embarrassing corrections, wants his reputation restored. His simple argument is of double standards: his data manipulations were deemed fraudulent while those of Jessus were declared the correct way to do science. The investigator of both Voinnet and Jessus namely was a personal friend of the latter, the Sorbonne plant biochemistry professor Francis-Andre Wollman, member of Academie des Sciences and Knight of the Honour Legion. Turns out, also papers co-authored by Wollman contain manipulated data.

Nature’s way

Wollman was investigator of both Voinnet in 2015 and Jessus in late 2017. The latter fact was uncovered on my site, thanks to a whistleblower, the former was leaked by Voinnet himself as soon as ETH unmuzzled him. How things changed in between those 2 years. Copy-pasting of gel bands in Photoshop suddenly became an example of good scientific practice, and so Jessus was acquitted in full. Which rule will Wollman apply to his own papers, where same kind of image irregularities was found as in works by Voinnet and Jessus? Does the distinction between research misconduct or good science depend on who does it? Is anyone responsible for anything at all? Does life science need data to be credible?

Everyone blames someone else to have conspired against them, and all of them blame me for everything. However, ETH professor Voinnet also blames his former right-hand man from Strasbourg Patrice Dunoyer (meanwhile exiled back to his home of New Caledonia) and declares to have smoked out that data faker himself, though we are not educated as to what Dunoyer has to do with Voinnet’s PhD papers or those lacking Dunoyer as coauthor. Even the journal Nature Genetics gets blamed: Voinnet declared that the editors have denied him his request to correct a paper (after I reported it to contain manipulated data). The French newspaper Le Monde recently brought a 6 part series about the Voinnet affair, and this is where we learned that

“For an article by Nature Genetics in 2013 [Mari-Ordonez et al 2013, -LS], faced with the opposition from publisher to issue corrections, he asked ETHZ to publish them as their own imprint. “It would have allowed my former student to have a complete resume, without hiding the problem with this article,” says Olivier Voinnet”.

The first author Arturo Mari-Ordonez is now group leader in Austria, and he had to correct his PhD thesis due to manipulated data. Now I understand why ETH refused me access to this dissertation back in 2015. As for the journal’s peculiar refusal to issue a correction: the journal’s former Editor-in-Chief Myles Axton departed to work with Wiley (incidentally, also he had some inappropriately presented data in his own papers), and the new editorial team seems to have little say on such matters. Instead, I received a reply from Springer Nature Head of Communications, Rebecca Walton, who refused to either confirm or deny what Voinnet told Le Monde. Three times I put the above Le Monde quote to her, and all I got back was an instruction to write something unspecific about Springer Nature being committed and confidentiality. Soon after, a tweet of mine where I questioned Nature editors’ qualifications and responsibilities, was instrumented by another Nature journal editor to set off a campaign accusing me of harassment of women, but also of editors and scientists in general.

So it seems Voinnet did not lie. Nature Publishing Group probably closed the case after discovering that it all was once again only my trolling.

Many investigations

Also University of East Anglia closed the Voinnet file. According to Le Monde, the English whitewashing exercise concluded in March 2017 and this was what they found:

“For four figures, these are honest mistakes, inadvertent copying and pasting of control bands. They are reused in three separate articles, for which the editors request corrections, accepting the unintentional mistake and noting that originals have been submitted or that other articles have confirmed the results. Note that in one of these cases, Olivier Voinnet admits having used a “mock-up figure” in the article. These mock-ups are usually built for internal presentations or drafts to see what the final version will look like. It is like when a “dream” becomes “reality”.

For two figures, East Anglia’s experts note an intentional alteration of the images. And for good reason, the then-doctoral student used a software to erase some unsightly dots in the background of an image, without affecting the data itself. Nevertheless, the editor of EMBO Journal decides for this reason to retract the article [Brigneti et al. 1998, -LS] (the original data could not be found). “I did not know it was happening at the time,” confesses the biologist today who adds that “it grips me at my throat”. He reluctantly accepted the publisher’s decision, citing the age of publication and its high citation rate”.

That EMBO J paper is the only one where Voinnet admits some fraud, a mistake of his youth. Otherwise: it’s always the Great Satan Dunoyer. Never ever did any of Voinnet’s time-saving data manipulation affect the validity of his research in any way. Just like we are now are educated by all Spanish authorities in Lopez-Otin’s case. There was that infamous Deleris et al Science 2006 paper which ETH wanted to retract in 2015, but the journal bulked, and issued a correction only. Le Monde writes:

“Here too, the errors, made by Olivier Voinnet, are obvious and not very glorious: bands have been copied and pasted, but mirrored. “I was not paying attention. I wanted to help my students and I did the work for them”, apologizes the researcher. “It was not my desire to cheat.”

Data fakery aside, that Science 2006 paper is scientifically utterly worthless, even according to Voinnet’s own follow-up publications. Yet there it is, never retracted and thus fully trustworthy.

The mere existence of the University of East Anglia investigation remained secret until after the ETH and the CNRS announced the outcome of their own second Voinnet investigation in 2018. In fact, it was ETH who pushed ahead, eager to declare their professor Voinnet a hapless victim of Dunoyer’s fraud, while making clear no further evidence against Voinnet will be ever admissible in the future. Thing is, in France Voinnet is still officially a fraudster, due to 2015 sanctions by CNRS, also their 2017/2018 investigation is not entirely in his favour, this was why CNRS wanted to keep their report secret. According to Voinnet, it was Jessus who coordinated the second investigation against him, and it’s probably true. The ETH professor now engaged lawyers to get all those CNRS sanctions lifted which prevent him from triumphantly returning to France. He is always mindful how Jessus was applauded for photoshopping gel images and copy-pasting bands, by same CNRS and same investigator Wollman when he was whitewashing her in late 2017 while the same time Jessus was sentencing Voinnet for tolerating Dunoyer’s fraud. Yes, it all is mental. Le Monde writes about Voinnet:

he stresses relentlessly the “double standard” which seems to have been shown in other recent investigations in his field, particularly that relating to the scientific output of Catherine Jessus, director of the Institute of Biological Sciences (INSB).

First, he notes that some manipulations of figures that he is accused of appear to be in the same category as those that got “accepted” for the director of the INSB. Then he notes that the absence of original data does not bother anyone in the case of his colleague. In addition, he points out that he was sanctioned as a team leader, which again is not blamed on the biologist [Jessus]. And finally, he accused the CNRS management of having done everything “to see nothing, do nothing” to determine the real responsibilities for the accusations he had to face”.

Inspector Voinnet

On 17 January 2019, a show took place in Paris which was just too bizarre. Voinnet spoke at a research integrity workshop organised by his new friend, Bruno Andreotti of EHESS. Next to Voinnet spoke Boris Barbour of PubPeer, and Olivier Le Gall, head of OFIS, the new central academic institution for research integrity in France. Le Monde journalist David Larousserie was there to watch The Olivier Voinnet Comeback Show:

“20% of figures” would be wrong because of him. “It was speed, bad work, because it did not interest me to assemble these figures”, he added. He also acknowledges that, without these shortcuts, “we would have been slower and that it could have affected [his] career”.

In an interview with Newstank, Inspector Voinnet positioned himself as the main investigator of his own fraudulent papers. He protests as to why he was not given access to his Strasbourg lab notebooks when the CNRS investigation started in 2015, so he could have exposed Dunoyer’s fraudulent activities earlier. Good point. But then imagine, purely hypothetically and for argument’s sake alone, Voinnet was not a paragon of ethics, but actually an extremely cunning fraudster himself. He would have used the opportunity to rig or destroy vital fraud evidence, wouldn’t he? It is now very reassuring to know that ETH let him have access to all such evidence at the Zürich lab during all times, right?

Newstank then quotes Inspector Clouseau, pardon Inspector Voinnet berating also PubPeer commenters for…. hiding evidence from him:

the fact that “there is a game on PubPeer resembling a sort of hunt” through which some people “deliberately will not raise all allegations at once and thus push a researcher to produce a correction which does not suffice.” “And on the day the publisher releases the correction, they destabilize it all again, whipping out everything they kept in reserve (…). It happened to us twice. “

These days, Voinnet is not the perpetrator, but one of research integrity experts, basically the man who, while himself harassed, gagged and persecuted, single-handedly exposed the biggest fraudster in the history of plant sciences: Patrice Dunoyer.

The treacherous essay

It makes sense now why a certain essay, authored by two CNRS researchers was never published. There, PubPeer co-founder Brendon Stell claimed credit for uncovering the Voinnet fraud scandal, together with Ivan Oransky of Retraction Watch. The essay which never saw the light of the day, except as a reference in another Watchdog article, was this one:

Guaspare C and Didier E (in press) The treachery of images: The Voinnet affair. In: Biagioli M and Lippman A (eds) Metrics and Misconduct: New Ecologies of Academic Research. Cambridge, MA: MIT Press.

It wouldn’t make sense today anyway, now that we know that Voinnet was a victim of someone else’s fraud and my trolling. Moreover, it seems the essay’s author Didier saw his wrongful ways and recanted. This from Newstank:

“Would you have had the same career without what you have been criticized? “asks Emmanuel Didier, researcher at EHESS, the biologist [Voinnet,- LS].

“The answer is yes. It probably would have been slower since you have to work a lot to reach the standards I set myself but which are well beyond a standard laboratory. One has richly deserved what one does but one does it. However, it is not me who decided that I was a star, it was other people who starified me and these are the same that destarified me then.

Would I have had such a meteoric career? Probably not. Does this fundamentally change our scientific discoveries? No, “replied Olivier Voinnet.

Pass the puke bucket. Back in 2015 I could not find a single scientist in the entire world who would have confirmed Voinnet’s central discovery of siRNA as mobile distance antiviral silencing signal in plants. But many said his results were not just irreproducible, Voinnet’s own papers contradicted themselves.

The original whistleblower in Voinnet affair, US plant scientist Vicki Vance,  not only caused the very first Voinnet retraction (Dunoyer et al, Plant Cell, 2004), but also proved his science as not reproducible. Jay  et al 2011 was corrected for data manipulations, but deemed otherwise rock-solid. In 2016, Vance lab submitted their own preprinted manuscript to this same journal, disproving the photoshopped Voinnet study. They desk-rejected by the PLOS Pathogens editors (one editorial board member is a close Voinnet collaborator), after a prolonged deliberation but without peer review. The study was the published in the journal Plant Physiology (Mlotshwa et al, 2016).

ETH knows all this very well, and so does CNRS.


Le Monde suspects there might be new retractions, also Voinnet indicates those could happen if CNRS gets their way, but I am sceptical. Voinnet enjoys 100% support from ETH, and his networks in Europe and US are still strong enough. Prestigious journals are eager to publish his papers. Voinnet is back on his two feet, and he proved to big to fail. And this is the main lesson of how research integrity works.

Another too-big-to-fail character, Catherine Jessus, solved her troubles with corrections, journals had to agree even if they didn’t seem to like it. Unlike Lopez-Otin, Jessus didn’t make the “mistake” of publishing with Journal of Biological Chemistry, who even do mass retractions if necessary. This is also why Lopez-Otin’s friend and his host in Paris, Guido Kroemer has nothing at all to fear in regard to his PubPeer record, neither from journals nor from his research institution Centre de Recherche des Cordeliers, which director he happens to be. And some journals don’t believe in corrections or retractions, like Molecular Cell (or Cell in general), this works in favour of former CNRS president Anne Peyroche, despite fraud findings. And some personalities are above such things. Or did you honestly expect a correction of this figure from the paper Vidal et al J Cell Science 2001, whose first author is presently Minister for Research and Innovation? The only public reply from the Government of France was to threaten legal actions against me for reporting this image duplication.

And as for data irregularities in Wollman I am about to present: nobody will  be interested. Sorbonne University will not even reply, no point of even trying. His Academie des Sciences were actually very active in endorsing Wollman’s whitewashing non-investigation of Jessus, while calling for the heads of critics and Le Monde journalist Larousserie (read here). They, the Sorbonne University and CNRS made their position about PubPeer evidence and my person specifically very clear. If the Voinnet affair happened now, he would probably be declared for his travails and retractions a martyr saint, as Lopez-Otin is in Spain. It is a huge mess, and it was only proper of CNRS to celebrate their 80 year anniversary with Jessus on stage.

Wollman’s dirty vest

Let’s hope that the society journals where Wollman’s papers were published will care more. I will start with Cardol et al PNAS 2009, Wollman is penultimate of 6 authors.

wollman 2
Somehow two images of a dish were reused, and rotated in the process. Can this happen by accident?

There is more in that paper, again with images of culture dishes. The following can never be a mistake, you will always remember copy-pasting the right-hand half of an image, flipping it, rotating it, and then neatly pasting it over a different image, while meticulously covering up all traces of this image splicing event. If you did that kind of data manipulation, you will have done that with full intent to deceive.

wollman 2.1

Whoever was responsible for this act of data fakery, we cannot know. What we do know is that Wollman is a certified expert for research integrity, and he must now decide which category this falls into: Voinnet-style or Jessus-style?

There are other issues which might be have been mistakes, but they still should be corrected. Like this Wittkopp et al Plant Journal 2018, freshly published, hence easy to fix. If Wollman (who is 2rd penultimate coauthor) thinks it should be fixed, that is.


Also this paper Malnoe et al Plant Cell 2014 is rather new, surely Wollman will want to correct this mistake of duplicated Ponceau S image (as reported on PubPeer a year ago) with correct data, being a known pedant for research integrity?


Or maybe not. As the current scandals in France, Spain and other countries show, research integrity is not something our scientific elites are to be bothered with. All scientists are peers, but some get more peerage than the others.


If you are interested to support my work, you can leave here a small tip of $5. Or several of small tips, just increase the amount as you like (2x=€10; 5x=€25). Your generous patronage of my journalism, however small it appears to you, will greatly help me with my legal costs.

  1. Smut Clyde

    some people “deliberately will not raise all allegations at once and thus push a researcher to produce a correction which does not suffice.”

    I did not previously realise that the unpaid post-publication reviewers who contribute to PubPeer have an obligation to find and report all the flawed or faked images in a paper, to save the researcher from having to search out (or remember) which images are faulty and need to be corrected.


    • adamselwith

      Yes, though what this also betrays is a high level of sloppiness, even negligence, during routine experimental operations. Very much in the vein of a creative artist, and how they may receive comments from art critics. Taking this point even further, and at the risk of entering well-worn argumentative waters, is Biology really a Humanities discipline in disguise of a Science Discipline?


  2. Perennial Nothern Blots over 23 times have been classic and tip of iceberg. We should recognize that Lopez-Otin malpractice has gone further beyond. It is much worse that they sell hope to progeria patients and swap their samples as shown in Nature Cell Biology paper (2015). Refer PubPeer. Their retraction note did not address the issues.


  3. CNRS has appointed a new interim head of biology branch to replace Jessus, Andre Le Bivic. Until his appointment on 1 February 2019, Le Bivic was director of Developmental Biology Institute of Marseille (IBDM).
    On 11 February 2019, Plos One issued an expression of concern for a 2013 paper from IBDM (last author Laurent Fasano). Raw data was either not available or didn’t match the published figures.
    “Following publication of this article [1], several concerns were raised about the Western blots in Figs 1, 5, and 6. The authors confirmed that in preparing these figures they had spliced image fragments to remove empty lanes, rearrange the sample order, and in some cases to combine lanes from short and long exposures of a given blot. The Director of the Institute for Developmental Biology of Marseille discussed this matter with the corresponding author and examined the original data underlying the results in question. The Director concluded that the images were modified for the purpose of presentation, and that the scientific results presented in the article and underlying data are sound”

    This Director was Le Bivic. Now you know what his attitude to research integrity is. A worthy replacement for Jessus.
