The student’s other activities and obligations during study shall develop independent research work and presentational and communications skills, through the obligation to publish papers and to participate in conferences with oral reporting and poster presentations. During the second year, the student shall be required to publish or have accepted for publication a scientific review paper in a journal that is reviewed internationally, upon which he/she shall have worked during the first year of study (a review of literature on the research). From the third year to the end of study, the student shall be required to publish a scientific paper with research results in a journal (Web of Science), and to present the results at an international conference, all with the objective of stimulating research excellence in both the doctoral papers and/or the Doctors of Science.
