Wansink's resignation at Cornell takes effect at the end of the academic year, the school said.

Wansink had previously helped update the USA dietary guidelines and is known for his research on consumer behaviour, which has been widely cited including in articles by The Associated Press.

"The committee found that Professor Wansink committed academic misconduct in his research and scholarship, including misreporting of research data, problematic statistical techniques, failure to properly document and preserve research results, and inappropriate authorship", a Cornell spokesman wrote in a statement Thursday.

In this December 6, 2016 file photo, Brian Wansink speaks during an interview in the produce section of a supermarket in Ithaca, N.Y. On Thursday, Sept. 20, 2018, the prominent Cornell professor announced heÂs retiring after a medical journal retracted six of his food research papers. Among the papers retracted by The Journal of the American Medical Association on 19 September are one finding that people ate more calories while watching a stimulating action movie than a tame interview show and another concluding that people given bigger bowls at a Super Bowl party served themselves more calories. After conducting an evaluation, Cornell told JAMA editors: "We regret that, because we do not have access to the original data, we can not assure you that the results of the studies are valid". "What we did not keep over the past 25 years are the original pencil and paper surveys and coding sheets that were used in these papers. That might be why they said they couldn't reproduce these from scratch (that is, there was no scratch)".

In April, JAMA warned readers about all of Wansink's articles published in its journals, the website Retraction Watch wrote.

Wansink said in a statement Friday his work had some statistical mistakes and other issues, but that he never intentionally misreported data.
