How do I find a place as a doctoral student?
In order for you to be able to take a doctorate at ETH Zurich, a professor there must be willing to supervise your thesis.
Doctorates are normally associated with an offer of employment. For this kind of doctoral position, it is best to apply directly to a potential supervisor for your thesis. Go to the website of the department in which you would like to take your doctorate and contact the possible professors directly.
