Please observe that it is impossible to register for PhD courses until 4 months before start.

Outside of AAU
If you are from outside Aalborg University and you wish to enroll in one of our PhD courses, you must create a profile. This is done by clicking on “create new account” and filling out the form in PhD Moodle.

Cancellation
Cancellations are accepted no later than 2 weeks before the start of the course. The Doctoral School has a no-show fee of DKK 3.000 for each course where the student does not show up.

Registered illness sent to the course organizer and the aauphd@aau.dk is of course an acceptable reason for not showing up on those days.

Diploma
All passed participants will receive a diploma as a PDF file.
The Doctoral School kindly ask for your patience, as it might take a while before you receive the final course diploma. This is due to the process of gathering evaluations.

Please address questions regarding the evaluation or issue of the diploma to the Doctoral School, via email at phdcourses@adm.aau.dk
