While duplication of images within the papers has been noticed, there is no duplication of images between papers

With 28 problematic papers, Dr. Chitra Mandal, a SERB Distinguished Fellow at the CSIR-Indian Institute of Chemical Biology (CSIR-IICB), Kolkata, has the most number of papers from the institution on the Pubpeer website. Pubpeer website allows independent scientists to publish post-publication review of scientific papers. Three other scientists (Dr. Hemanta K Majumder, Dr. Uday Bandyopadhyay and Dr. Nahid Ali) from CSIR-IICB have one problematic paper each listed on Pubpeer.

Papers of Dr. Mandal's and the other three scientists on Pubpeer have problems with the images —manipulation and/or duplication.

While duplication of images within the papers has been noticed, there is no duplication of images between papers. One paper of Dr. Mandal published in 2009 has already been retracted.

Except in three, she is the corresponding author in the remaining papers, including the retracted paper.

All the problematic papers from CSIR-IICB listed on Pubpeer website were double checked for image problems by Dr. Elisabeth M. Bik, Science consultant at Harbers-Bik LLC, San Francisco, California. Dr. Bik is an expert at identifying manipulated and duplicated images.

Not aware of this website

“I have not seen this website nor do I know anything about it,” Dr. Mandal told The Hindu.

However, according to FAQ posted on the Pubpeer website on whether authors receive alerts when someone comments on their paper, it says: “Yes. Authors are automatically alerted when their paper is commented… We make every effort to alert the authors to any comments and they are encouraged to respond.”

In one of Dr. Mandal’s papers listed on Pubpeer, the first author has responded several times.

“The research has been carried out in different stages of my life in a span of 15 years with the help of hard working, motivated students who are currently in different parts of the world,” Dr. Mandal said in an email to The Hindu.

She added: “I am ready to show all the original data to any reputed scientific body that wants to understand my scientific claim published in the respected journals.”

“Moreover, this matter has already been discussed with the highest scientific body. Such a high-level scientific committee will look at these unintentional human technical errors. I would strongly say that these unintentional minor mistakes do not alter the major scientific outcome and information from these experiments. Subsequently, if suggested by the committee, it will be informed to the respective journals,” Dr. Mandal said.

Area of work and recognition

Dr. Mandal has about 80 select publications in the area of cancer and sialoglycobiology of visceral leishmaniasis (VL) and Pseudomonas aeruginosa according to her bio posted on the institution website.

She was an Acting Director CSIR-IICB in 2014-15. She had received the Sir J.C. Bose Fellowship by the Department of Science and Technology (DST). She has been elected fellow of The Indian National Science Academy (New Delhi), Indian Academy of Sciences (Bangalore), The National Academy of Sciences (Allahabad), National Academy of Medical Sciences and West Bengal Academy of Science and Technology.
