The Idiap Research Institute seeks qualified candidates for 1 postdoctoral position on the topic of Foundation Models for Audio-Visual DeepFake detection. The position will be aligned with the new project « DEmocracy and Media Oversight in the era of AI and disinformation ( DEMO-AI ) » funded by the Haster and Mercator Foundations under the joint program Digitalization & Democracy ( https://haslerstiftung.ch/die-fordertatigkeit-der-hasler-stiftung/foerderprogramme/hmdd-2025/ ) and should be filled as soon as possible. 

 

The Postdoc candidate will work within the Biometrics Security & Privacy group under the supervision of Prof. Sébastien Marcel.

 

Postdoc appointments are typically for one year, with possibilities of renewal, conditional to performance.
