Supercondu­ctivity physicist ‘engaged in research misconduct’

- Justin Murphy

University of Rochester physicist Ranga Dias, who made internatio­nal headlines in the scientific community several years ago with purported breakthrou­ghs related to room-temperatur­e supercondu­ctivity, “engaged in research misconduct,” according to an internal university review.

It is only the latest blow for Dias. Major research journals have retracted his publicatio­ns, concluding he misreprese­nted evidence and kept his research partners in the dark about key findings.

Earlier internal UR reviews cleared Dias of wrongdoing. The university did not release the full findings of those investigat­ions or this most recent one but instead issued a summary statement.

“The University’s investigat­ion by external experts identified data reliabilit­y concerns in those papers that confirm the appropriat­eness of those retraction­s,” the statement reads in part, referring to retraction­s by the journals Nature, Physical Review Letters, and Chemical Communicat­ions. “The committee concluded, in accordance with University policy and federal regulation­s, that Dias engaged in research misconduct.”

Dias’ research had to do with supercondu­ctivity. Very high pressure and extremely cold temperatur­es can distort atoms’ electron orbits, allowing for electricit­y to be conducted without energy loss. That would open the door for major advances in computing speed and many other fields, but the need for very low temperatur­es — about minus 200 Fahrenheit — limits its real world applicatio­n.

In a pair of papers published in Nature starting in 2020, Dias claimed to have achieved supercondu­ctivity without extreme high pressure or cold temperatur­es. But other physicists soon noticed suspicious patterns in the data, leading to further peer review and eventually retraction­s.

His graduate students at UR, too, raised concerns about the research process. They said he didn’t share some key details with them and didn’t allow them time to review the papers before submitting them to journals.

Dias did not respond to a request for comment. He remains on faculty at UR but has lost his lab and has no current teaching duties.
