The German Research Foundation (DFG) has announced today that it is withdrawing a professorship it awarded leading diabetes researcher Kathrin Maedler in 2014.
In recent years, Maedler — based at the University of Bremen in Germany — has faced questions about her work, including allegations of duplication and image manipulation. So far, she has issued one retraction, two expressions of concern, and multiple corrections. After an investigation, the University of Bremen concluded last month that Maedler’s work contained several duplications that were the result of negligence, noting there is not enough evidence to support charges of scientific misconduct.
But this hasn’t stopped the DFG from revoking the prestigious Heisenberg professorship it awarded Maedler in 2014. A Google-translated version of statement released by the DFG (in German) today concludes that Maedler did, in fact, commit misconduct, as she
Several duplications in the work of a prominent diabetes researcher were the result of negligence, but there is not enough evidence to support charges of misconduct, according to an investigation at her university in Germany.
Recently, we’ve reported on several notices for papers co-authored by Kathrin Maedler, a researcher at the University of Bremen. So far, Maedler has one retraction, multiple corrections, and two expressions of concern to her name, after several of her papers were questioned on PubPeer. Previously, the University of Zurich in Switzerland — where Maedler completed her PhD in 2002 — determined there was a lack of evidence to support allegations of misconduct in papers that were part of her doctoral thesis.
Diabetes has issued two expressions of concern (EOCs) for papers co-authored by leading diabetes researcher Kathrin Maedler, adding to her previous count of one retraction and three corrections.
Both papers were questioned on PubPeer, alongside several others co-authored by Maedler, who is based at the University of Bremen in Germany. As we previously reported, PubPeer comments have led to one retraction for Maedler in the Journal of Biological Chemistry (JBC), and corrections in various other journals.
One of those corrections has now earned an EOC from Diabetes, which also extends to the original paper. Here are the notices, which asks the University of Bremen to investigate further: Read the rest of this entry »
A journal has retracted a paper by a leading diabetes researcher — who has also issued three corrections — after questions about her research were raised on PubPeer.
The ongoing comments have led Maedler to carefully look through her original data, according to a statement she emailed us: Read the rest of this entry »
Prominent German diabetes researcher Kathrin Maedler has issued corrections on two papers, and told Retraction Watch she is in the process of defending the data on others.
14 of her papers have been critiqued by PubPeer commenters. The commentary, which spans from her graduate work in 2002 to a 2014 publication in Nature Medicine, includes questions about image manipulation and self-plagiarism.
Here’s a comparison between figures in Maedler’s 2009 PLoS One paper, “Deletion of the Mitochondrial Flavoprotein Apoptosis Inducing Factor (AIF) Induces β-Cell Apoptosis and Impairs β-Cell Mass,” and one she co-authored in 2006 in Diabetes, “Low concentration of interleukin-1beta induces FLICE-inhibitory protein-mediated beta-cell proliferation in human pancreatic islets,” via PubPeer: Read the rest of this entry »
