PhD Opening @ VUB - Multimodal Fake Media Detection

PhD Researcher in Multimodal Fake Media Detection

The rise of fake news has brought with it many different modalities of misinformation. Images can be falsified or taken out of context, videos can be edited to be misleading and deep-fake video can make and portray events that have never happened. The complexity of this manipulated or generated content requires new fake media detection methods that can combine different modalities (e.g., image and text, video and audio) and can aggregate supporting evidence from multiple sources (e.g., news websites, fact-checking websites, social media).

This fully funded PhD position will design novel deep-learning models to detect fake media from multimodal content (images/video and text/audio). The research will also investigate (graph) deep learning models for multidomain and multilingual automated fact-checking, which can reason on the veracity of content using evidence from multiple sources. The research will also focus on innovative post-hoc interpretation and explanation algorithms that analyze the behavior of the (multimodal) deep learning models.

The position is available within the team of Prof. Nikos Deligiannis at the Department of Electronics and Informatics ( at Vrije Universiteit Brussel, Belgium, which specializes in interpretable and explainable machine learning, signal processing, and federated learning for computer vision and data processing. The team is affiliated with imec, an international R&D and innovation hub in nanoelectronics and digital technologies (
