Public defence at Aalto University

During the public examination of the doctoral thesis, or the defence, the doctoral student defends the results of their doctoral thesis against public criticism and answers questions presented by the opponent, who has been appointed to evaluate the thesis. The course of the public defense is supervised by a custos, who usually is the supervising professor of the doctoral student. During this process the doctoral student is called the respondent. The public defence is also a ceremonial occasion that follows the academic traditions of each field.

On this page you can find Aalto University's instructions for arranging public defences.

Date and time of the defence

The doctoral student agrees the date of the defence with the opponent and the custos. The date and time of the defence are then confirmed by the Doctoral programme committee of the School. This can happen in the same meeting where the permission for defence is granted or later, depending on the School.

Customarily the defence begins at 12 noon sharp and takes approximately 2 hours. The audience must enter the hall by 12 noon, but the repondent, opponent and custos enter at 12:15 sharp.

  1. at the premises of Aalto University
