Prospective PhD Candidates

The Graduate School of Science offers 9 PhD Programmes, spanning the entire spectrum of science.

Finding a supervisor

Finding the right supervisor is a key element and the first step in the process of obtaining a doctorate. The supervisor has to confirm that she/he is willing to accept you as a PhD candidate (promovendus) before any further steps can be taken. Contact a professor or senior staff member directly: contact information can be found searching by name or at the website of the Research Institute in your area of interest.


Steps described below in short are described in detail in the Leiden University PhD Regulations.

Register at the Graduate School of Science by sending an email to the Graduate School Office of Science: gsoffice@science.leidenuniv.nl.

Certified copies (in paper form) of your Master's diploma including transcripts and English translation need to be sent to the Graduate School Office, preferably directly by the University issuing the diploma in a sealed envelope.

For international applicants additional administrative procedures may apply in relation to visa, residence permit and/or work permit requirements set by the government. The Service Centre International Staff (SCIS) will assist you in applying for the necessary permits.

As soon as possible after the start of your PhD, the Dean of the Faculty of Science will officially need to appoint your supervisor(s) (promotors) and co-supervisor(s) (co-promotors). Therefore, the PhD candidate needs to send an official request to the Graduate School of Science using appendix 2 within 6 weeks after the start of the PhD Programme. 

Upon completing your thesis, you will need to follow the procedure as described in the Timetable of the Procedure.
