Retractions
In 2022 it was reported that a joint investigation by the University of California San Francisco and the San Francisco Veterans Affairs Medical Center revealed examples of fabrication or falsification in some of Dahiya's published work. As of 2022 Dahiya has had four of his research publications retracted, one paper has received an expression of concern, and one paper has been corrected. It appears that this issue may have resulted from a UCSF data preservation policy.
