Do I need to look for a potential supervisor before applying to Autonomous Universities PhD Programme / AISG PhD Fellowship Programme?

It is not a necessary requirement to have a potential/confirmed supervisor for your application. However, it is highly encouraged that interested applicant to speak to those potential supervisors in mind. You should assess if their AI research areas are a fit and if you feel comfortable to work closely with your supervisor(s) throughout your whole period of PhD candidature period (up to 5 years).
