The students and fellows in the MPRTN are mentored by PIs and collaborators of the network. The mentor is responsible for providing the essential opportunity to develop research skills of the student or fellow. In a well-functioning research lab, as is the case with all PIs in the MPRTN, these skills are taught by example and trainees participate in the definition of their research topic, are guided in performing a detailed literature study, have regular meetings with supervisor and committee, do research presentations, attend national/international conference and participate in writing and reviewing of publications. The MPRTN provides tools to help develop special skills, in addition to these. These tools consist of courses, workshops and events as well as the opportunity to take their research to the most appropriate lab or location.
