Lorenza S. Colzato (born 20 September 1974) is an Italian cognitive psychologist who is best known for the attention she received in the mainstream media in the Netherlands for multiple incidents of scientific misconduct.
[12] Since 2019, Colzato's work at Leiden University was being investigated for various alleged breaches of academic integrity, including data manipulation, misattribution of authorship, and collection of blood samples without permission from the Medical Ethical board.
[17] She pointed out that one of the accusers, a PhD candidate at that time, was the person who actually performed the study (which the medical ethics review board declined to approve), took the blood samples and was the lead and corresponding (hence, responsible) author of one of the two articles in question.
On 21 September 2020, the Dutch newspaper NRC Handelsblad reported that Leiden University had, in August, made Colzato's provisional dismissal a definitive one.
[24][2][25] In a supplementary decision on 17 May 2022, the executive board of Leiden University has concluded that it will publish the titles of seven articles in which there is evidence of malpractice.
