This training is aimed at various groups. On the one hand, students and professionals who want to do their doctoral thesis about criminal law.

In this context it is convenient to indicate that the criminal Law has traditionally been, and remains, one of the preferred options by the students who choose these professional opportunities, highlighting the high percentage of students with an excellent academic record. It is also suitable for the graduates who want to break into the labour market, assuming attributions in the criminal field. Also for those who are already working and want to get specialised in this branch or widen their knowledge.
