Scientific integrity

Integrity and Ethics

Everyone involved in teaching and research at Maastricht University shares in the responsibility for maintaining academic integrity. All of our academic staff are expected to adhere to the general principles of professional academic practice at all times.

Maastricht University endorses the principles of professional scientific conduct as expressed in the Netherlands Code of Conduct for Scientific Integrity and has established its own 'Regulation for Scientific Integrity at Maastricht University'. This is in compliance with the overarching UM Integrity Code of Conduct.


In case of questions or complaints concerning scientific integrity, the confidential advisors on scientific integrity are the primary contact persons. They will try to mediate in the complaint or to reach a solution. If this is not possible, they will guide the complainant in filing the complaint with the UM Committee on Scientific Integrity. Ph.D. candidates who have questions or complaints concerning scientific integrity can also contact the confidential advisor at their faculty, before contacting the UM advisors on scientific integrity.


Within UM, prof. Herman Kingma, dr. Ree Meertens and prof. Sophie Vanhoonacker-Kormoss act as the confidential advisors on Scientific Integrity. You can contact the confidential advisors by email at or call the secretary to the confidential advisors, Arnold Verhoeven, at +31 (0)43 388 2350.

Committee for Scientific Integrity

The Committee for Scientific Integrity advises the Executive Board on complaints filed regarding scientific integrity. The Regulation for Scientific Integrity defines what constitutes a violation of scientific integrity and the procedure for submitting a complaint.

The independent committee consists of prof. dr. Bruno de Witte (chair), prof. dr. André Knottnerus, prof. dr. Marleen van Baak and dr. Sjaak Koenis. The committee is supported by a secretary.
