Purpose

SUMMARY: Findings of research misconduct have been made against Carlo Spirli, Ph.D. (Respondent), who was an Assistant Professor of Medicine, Department of Digestive Diseases, Yale University (YU). Respondent engaged in research misconduct in research supported by U.S. Public Health Service (PHS) funds, specifically National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), National Institutes of Health (NIH), grants R01 DK079005 and P30 DK034989. The administrative actions, including debarment for a period of four (4) years, were implemented beginning on March 28, 2023, and are detailed below.

FOR FURTHER INFORMATION CONTACT: Sheila Garrity, JD, MPH, MBA, Director, Office of Research Integrity, 1101 Wootton Parkway, Suite 240, Rockville, MD 20852, (240) 453-8200.

SUPPLEMENTARY INFORMATION: Notice is hereby given that the Office of Research Integrity (ORI) has taken final action in the following case:

Carlo Spirli, Ph.D., Yale University: Based on the report of an investigation conducted by YU and additional analysis conducted by ORI in its oversight review, ORI found that Carlo Spirli, Ph.D., former Assistant Professor of Medicine, Department of Digestive Diseases, YU, engaged in research misconduct in research supported by PHS funds, specifically NIDDK, NIH, grants R01 DK079005 and P30 DK034989.

ORI found that Respondent engaged in research misconduct by knowingly, intentionally, or recklessly falsifying and/or fabricating data included in the following four (4) published papers, two (2) presentations, and three (3) grant applications submitted for PHS funds:

  • R01 DK079005-11A1, Epithelial Angiogenic Signaling in Biliary Pathophysiology and in Polycystic Disease, submitted to NIDDK, NIH, on December 13, 2018. Administratively withdrawn by the funding agency on March 1, 2021.
  • R01 DK090021-01 ``Mechanisms of fibrosis in fibrocystin-deficiency associated cholangiopathies' submitted to NIDDK, NIH, on February 2, 2010. Administratively withdrawn by the funding agency on July 1, 2012.
  • R01 DK090021-01A1 ``Mechanisms of fibrosis in fibrocystin-deficiency associated cholangiopathies' submitted to NIDDK, NIH, on November 11, 2010. Administratively withdrawn by the funding agency on July 1, 2015.

Respondent knowingly, intentionally, or recklessly falsified and/or fabricated Western blot image data for cholangiopathies in a murine model of Congenital Hepatic Fibrosis (CHF) by reusing blot images, with or without manipulating them to conceal their similarities, and falsely relabeling them as data representing different experiments or proteins and falsifying quantitative data in associated graphs purportedly derived from those images in twenty-one (21) figures included in four (4) papers, two (2) presentations, and three (3) grant applications. In the absence of reliable image and numerical data, the figures, statistical analyses, and related text also are false.

Specifically, the respondent reused Western blot images from the same source and falsely relabeled them to represent different proteins and/or experimental results in:
