A scientific journal has retracted 60 papers linked to a researcher in Taiwan, accusing him of “perverting the peer-review process” by creating fraudulent online accounts to judge the papers favorably and help get them published.

Sage Publications, publisher of The Journal of Vibration and Control, in which the papers appeared over the last four years, said the researcher, Chen-Yuan Chen, had established a “peer-review and citation ring” consisting of fake scientists as well as real ones whose identities he had assumed. It said that in at least one case, Mr. Chen, who also uses the first name Peter, reviewed his own paper using one of the aliases.

In all, Mr. Chen, an associate professor of computer science who resigned in February from the National Pingtung University of Education amid an investigation, appears to have created 130 email accounts that were used in reviewing the papers. A spokeswoman for the publisher said it had contacted all the accounts but received no replies.

Sage said that the retracted papers all had at least one author or reviewer implicated in the ring, and that it was possible that other scientists were involved in the activity.
