(important changes to the previous version appear in color)

The PhD program is organized in accordance with this regulation, the provisions of the Greek Ministry of Education, Religious Affairs and Sports Law 4957/2022 and subsequent amendments and decisions.

Article 1
General provisions
SPEM offers a doctoral program which includes coursework and research towards a doctoral dissertation. There are no tuition fees.

Article 2
Purpose
The objectives of the program are:
a) Creation of new knowledge and development of high-level innovative methods through education of students and participation in original basic and applied research in a production engineering and management-related field of their choice.
b) Training scientists to be capable of contributing to the advancement of science and technology and undertaking leadership tasks in their professional or academic career.

Article 3
Awarded title
The program awards the title "Doctor of Philosophy (Dr.) of the Technical University of Crete."

Article 4
Administration bodies
Apart from TUC Senate and the school Dean, decisions regarding the administration and operation of the program are taken by the SPEM assembly (hereinafter "Assembly") in accordance with the current legislation. The Assembly is also competent to draw up and submit to the Senate proposals for drafting, amending or revising the regulation of doctoral studies.
For the orderly operation and monitoring of the program, the Assembly may appoint a doctoral program coordinating committee (CC), an advisory body composed of the doctoral program director and four other school faculty members.

Article 5
Admission to the program
1. Applicants must have a master's or integrated master's degree from a national or overseas higher education institution with a grade point average at least 8/10 (equivalent to 67.5% in the UK grading system and B+ in the US grading system). If the latter criterion is not met, the Assembly decides on a case-by-case basis, taking into account the applicant's research work and academic qualifications.
2. Applications are accepted throughout the year and include:
a) Online application with information about the applicant, the dissertation committee, the supervisor, the language for writing the doctoral dissertation, and the proposed courses of the program to attend. Doctoral students must successfully complete at least four (4) courses corresponding to thirty (30) ECTS (European Credit Transfer and Accumulation System) credits during the first two years of the doctoral studies, in accordance with par 1 and 4 of article 7 hereof.
b) Copies of documents with degrees and transcripts from all institutions graduated. If a required degree has been obtained from an overseas higher education institution, both the institution and the degree must have been included in the respective Registries of the Hellenic National Academic Recognition and Information Center (Hellenic NARIC). In accordance with the current legislation, special procedures are followed if: (i) the overseas institution or the degree is not included in Hellenic NARIC’s Registries, or (ii) the degree is obtained from a foreign institution that has agreement with a private entity in Greece.
c) Copies of papers published in scientific journals and conferences or other information publicly available relevant to the applicant's research work.
d) Detailed curriculum vitae.
e) A PhD research plan, approved by the supervisor, in which the scientific field, research objectives, proposed methodology, expected results and contributions, bibliography and a general schedule are described.
f) Knowledge of the English language, proved from relevant certificates (level B2) or, according to the judgment of the Assembly, from studies at Universities with English as the official language.
g) Two letters of recommendation sent electronically to the School Secretariat.
h) Photocopy of ID or passport.
i) Photograph.
3. The application is evaluated by the Assembly following a proposal by CC or the program director and the opinion of the proposed supervisor. If the application is approved, the Assembly designates the language of writing of the dissertation and the courses to be completed by the student.
4. Applications for changes in the title or the content of the dissertation are accepted with the consent of dissertation advisory committee. If the Assembly deems that the requested revisions constitute a substantial modification of the original dissertation, it considers this to be a new application for admission to the doctoral program.
5. The courses to be completed by the student are designated in accordance with paragraphs 1 and 4 of article 7 hereof.

Article 6
Dissertation advisory committee and supervisor
The dissertation advisory committee (AC) supports and monitors the progress of the student. It consists of the supervisor, who must be a SPEM faculty member, emeritus professor, retired faculty or affiliated faculty member, and two more members who may be faculty members, professors emeriti, and researchers of Greek or international universities and research institutions. At most one member of AC can be a retired faculty member of a Greek university. All the members of AC must have scientific subjects relevant to the dissertation.
In the event of moving to another school or university or retirement, the supervisor or member of AC may continue to serve the committee and the doctoral program, and the doctorate is awarded by TUC.
Replacement of the supervisor or an AC member who cannot fulfill the delegated duties is approved by the Assembly, following an application by the student or the supervisor/AC member. The replacing supervisor is preferably one of the other AC members. The replacing member must satisfy the provisions of the first paragraph of this Article.
Any problems that result in impossibility of cooperation of the student and the AC are referred for resolution initially to the CC or the person appointed for handling complaints or grievances and, if no resolution is reached, to the Assembly and the competent TUC bodies.
The number of doctoral students supervised by a faculty member should be compatible with the supervisor workload and the available infrastructure of SPEM.

Article 7
Curriculum
1. Program structure:
a) The program includes coursework to provide students with the scientific background required for their research.

4. The Assembly, after verifying the fulfillment of the formal obligations of the student (certification of courses, publications, etc.) sets up the dissertation examination committee taking into account the opinion of the AC. According to the current legislation, the examination committee can be set up even despite a negative recommendation of the AC, as long as the student has fulfilled the all requirements for the doctoral defense.
5. The examination committee is made up of seven (7) professors with adequate knowledge of the subject of dissertation, of which three (3) are the AC members and the other members are appointed by the Assembly. At least four (4) members of the examination committee must be TUC faculty members and at least two (2) must be SPEM faculty members. The other committee members must belong to the categories provided by the current legislation for the composition of the AC, as described in Article 6 but without the restriction on the number of retired faculty members.

4. During the dissertation defense, the doctoral student orally presents the dissertation before the examination committee members and the public. This event, which takes place either in person or via teleconference media, is presided over by the Dean of the School or, in his absence, the supervisor of dissertation.
5. After the presentation of dissertation, the student answers questions from the examination committee members and, with their consent, from the other audience.
6. The committee then deliberates without the presence of third parties, judges the work in terms of quality, completeness, original thinking and contribution to science, and makes one of the following decisions:

a) With the consent of at least five (5) members the defense is deemed successful and the dissertation is approved as is.
b) With the consent of at least five (5) members the defense is deemed successful and it is decided that the dissertation needs minor improvements, according to remarks summarized in the dissertation assessment report.
