• Well I’m no expert here Sarah but I would have expected you to have been asked to sign a consent form explaining what data would be collected and how it would be used.  Could you ask the university to let you have details of the ethics committee that agreed these studies (they should have been given a reference number) – research participants do have rights to complain and perhaps this is the best way to take it forward now. Should the ethical dilemmas of doing research this way not have been explored in their theses?  The supervisors and the external examiners should have looked for evidence that the research was conducted ethically.
