Your university or department may offer courses in ethics and good research practice in your field. In some PhD and licentiate programmes courses in ethics may be mandatory, through the general study plan.
In the absence of such a course, you can learn about ethics and good research practice from your supervisors and others in your research environment. Some universities or departments have dedicated support structures, such as offices for research ethics, where you can ask questions about good research practice and be pointed to further resources. In the absence of dedicated support, you may find help in other structures, such as, for example, offices for research support, offices for innovation, offices for grants applications, data management offices, or the legal counsel at the university. You can ask your student union, the ombudsperson for doctoral students, or the trade union, for help.
