A journal has followed through on its promise to retract all articles by an education researcher, after an investigation raised questions about the validity of the data in some of his work with children with special needs.
The latest notice — which includes a list of 11 papers — brings the total number of retractions for Noel Kok Hwee Chia to 21.
Last spring, The Journal of the American Academy of Special Education Professionals (JAASEP) pulled nine articles by Chia that were the subject of an investigation at the National Institute of Education in Singapore, part of Nanyang Technological University, where he worked until April. As we reported in June, editors explained in a 3,000-word notice that they planned to pull every article that Chia had published in JAASEP.
The new retraction notice quotes from the reasoning presented in the previous one, from last spring:
According to the retraction notices issued by Chemosphere, Hong-Wei Luo incorrectly claimed to be affiliated with the Oak Ridge National Laboratory (ORNL) in Tennessee in one of his three affiliations. His other institutions listed on the papers include universities in Singapore and China.
However, an official from the Nanyang Technological University (NTU) in Singapore, told us the work in the now-retracted papers was not carried out at the NTU either.
A research fellow at Harvard Medical School whose PhD was revoked last month is no longer working in his former lab, Retraction Watch has learned.
An archived version of the lab site for Alfred Goldberg from December, 2015, lists Sudarsanareddy Lokireddy as a postdoctoral fellow; however, Goldberg’s current lab site doesn’t include Lokireddy as a lab member.
We contacted Goldberg’s lab, and he was unavailable for comment. We were told all of his lab members are on the current website.
Lokireddy has also logged his sixth retraction. But this case isn’t as straightforward as it seems.
A research fellow at Harvard has lost his PhD from a university in Singapore after being found guilty of falsifying data, and his former group leader’s contract has been terminated by his institution.
But that’s not the whole story. This tangled mess involves not only the Harvard researcher, Sudarsanareddy Lokireddy, and his former boss, Ravi Kambadur at the Nanyang Technological University (NTU) in Singapore, but an as-yet unnamed colleague of theirs who, we’re told, has admitted making up data in three papers, on which Lokireddy and Kambadur are co-authors. Bear with us as we walk you through this tale.
Two of those papers have been retracted by The Journal of Biological Chemistry (JBC); one in Molecular Endocrinology has yet to be pulled. Kambadur, who held joint appointments at the NTU and the Agency for Science, Research and Technology (A*STAR) in Singapore, has now had his contract terminated at both institutions.

In addition, a forensic investigation at Noel Chia’s institution — the National Institute of Education in Singapore, part of Nanyang Technological University (NTU) — suggested that some signatures providing parental consent might not be authentic. The investigation was also unable to authenticate the Malaysia-based organization Chia said collected the data on his behalf.
Nine of the papers appear in the Journal of the American Academy of Special Education Professionals (JAASEP), which has declared it plans to retract every article Chia has ever published with them (we’ve counted an additional nine papers).
Much of the information we know about the case stems from the unusually detailed — 3,000 word — retraction notice from JAASEP:
After an investigation found evidence of misconduct, a biologist has issued a third retraction.
Sudarsanareddy Lokireddy — now a research fellow at Harvard Medical School — “admitted falsification,” a Research Integrity Officer at Nanyang Technological University in Singapore told us in December. According to The Scientist, another journal has also published a correction that the authors had requested earlier.
The newly retracted paper is “Myostatin is a novel tumoral factor that induces cancer cachexia,” published in Biochemical Journal and cited 40 times, according to Thomson Reuters Web of Science. Here’s the retraction note:
Second of 3 retractions appears for biologist, the result of “a substantial number of falsifications”
First author Sudarsanareddy Lokireddy, now apparently a research fellow at Harvard, did not agree to the retraction, the result of “a substantial number of falsifications.”
In December, we covered the results of the NTU investigation, where Lokireddy used to work. During that investigation, he admitted to falsifying data, Research Integrity Officer Tony Mayer told us. The end result: three retractions.
One of those papers was retracted by Cell Metabolism in December. The second paper, published in Molecular Endocrinology, has been cited 52 times, according to Thomson Scientific’s Web of Knowledge. The retraction note explains which figures were falsified:
PLOS ONE has quickly corrected an October analysis of what children in Malaysia eat for breakfast, after the study
neglected to note it benefited from mistakenly noted an unrestricted research grant from cereal companies supported author salaries. The grant supported the salaries of research assistants, according to the correction note.
Per the authors’ request, the journal has noted that the study received financial support from Nestlé R&D Center in Singapore and Cereal Partners Worldwide, a collaboration between General Mills Inc. and Nestlé S.A., with the goal of selling cereal outside the US and Canada. These funders provided “salaries for research assistants” for the MyBreakfast study, on which the analysis is based, according to the note.
The paper includes authors affiliated with Nestlé and Cereal Partners Worldwide, as well as a detailed “Competing interests” section, which outlines the relationships with these companies.
The correction note explains the information that should have appeared in the funding section of the article:
Authors have retracted papers from Cell Metabolism and the Journal of Biological Chemistry after an investigation in Singapore found issues, including falsified data. The investigation is ongoing, and two additional retractions, along with two corrections, are on the horizon.
The investigation looked into papers by first authors Sudarsanareddy Lokireddy, now a postdoc at Harvard, and Sandhya Sriram, a postdoc at the Agency for Science, Technology and Research in Singapore. Led by the Nanyang Technological University in Singapore, where some of the work was done, the investigation concluded that there were issues with six papers on which either Sriram or Lokireddy was first author.
According to a notice from the NTU, the “investigation found a number of instances of alterations to data” in three papers on which Lokireddy is first author. One of those was retracted December 1 by Cell Metabolism: Read the rest of this entry »
Since our recent coverage about a university investigation that led to multiple retractions for nursing researcher Moon-fai Chan, we’ve been alerted to a few more retractions and errata. His total is now at six retractions and four errata.
Some of our finds were published this year, and some are a few years old. Most are due to duplication; one is due to “use of a dataset without ethical approval.” Chan — now the Associate Master and Chief of Students at the University of Macau — is the first author on all but one of the papers.
We’ll start with the most recent errata. Three of Chan’s articles in the Journal of Clinical Nursing have errata notes published online in July of this year, all noting that the authors used elements of some of Chan’s other articles. Here’s the erratum note for “Exploring risk factors for depression among older men residing in Macau:”
