The University has carried out an investigation under its Code of Practice and Procedure on Academic Integrity in Research which resulted in findings that Dr Alexander Liu was responsible for misconduct in research in respect of two papers identified below. These were retracted by the Journal of the American College of Cardiology on 1 September 2020 following a vote by its Ethics Board. 

The Panel’s findings were based on their judgement that Dr Liu showed a pattern of deliberately manipulating data such that in accordance with the Code there was an intention to commit Misconduct in Research. In the Panel's assessment, these instances of misconduct in research did not derive from inadequate supervision or training. 

Dr Liu disagrees with the Panel’s findings and has raised a complaint with the Office of the Independent Adjudicator for Higher Education (OIA). As the investigation process and the Panel’s report are confidential and the complaint to the OIA is ongoing the University is unable to comment further at this time.  No other co-author was found to be involved in the misconduct.     


Background information  

Misconduct in Research under the University’s Code of Practice means actual or attempted acts of fabrication, falsification, plagiarism or deception when proposing, conducting or reporting results of research, or deliberate, dangerous, reckless or negligent deviations from accepted practices in carrying out research.  It does not include honest error or honest differences in the design, execution, interpretation or judgement in evaluating research methods or results, or misconduct unrelated to the research process.    


In accordance with the Code the investigation was conducted by an independent 3 member Panel. The investigation involved careful consideration of the evidence, the internal management and training and supervisory procedures for the research and interviews with relevant persons including Dr Liu and co-authors on the two papers,
