The International Conference "Doctoral Research and Public Sphere: An Interaction" aims to bring together various research models, methods and instruments inherent to a research process as important as conceiving and writing a doctoral thesis. When it comes to putting down in writing the results of a research, a thought arises instantly in every researcher's mind: the fact that the research will become public and when that occurs, all the information will no longer belong exclusively to him. What happens when a research project transgresses the private sphere and is launched into the public one? What is the impact of a doctoral research in the public sphere? What are the ethical aspects involved in a doctoral research? How is it possible to separate relevant knowledge from useless one? These are some questions that will be addressed during the conference.
