Dear all,

We are looking for a motivated PhD student to join our project "Social Cognition In Silico and In Vivo" (SCIVIS). The research is embedded in a vibrant and interdisciplinary research network, and conducted in close collaboration with the Research Unit Brain & Cognition at KU Leuven (https://ppw.kuleuven.be/bc), known for its expertise in experimental psychology and cognitive neuroscience, and the AI Lab of Vrije Universiteit Brussel (Free University of Brussels, https://ai.vub.ac.be), a leading center in artificial intelligence research. Together, these partners bring complementary strengths to the study of social cognition, linking brain, behavior, and computation.

This position is located at the Vrije Universiteit Brussel, Brussels, Belgium.

Position description

Are you a computer sciencist with an interest in psychology? Do you want to advance the state-of-the-art in Artificial Intelligence while also improving our understanding of the human brain? Does interdisciplinary research spark your interest?

The Artificial Intelligence Lab<https://ai.vub.ac.be> at VUB university is looking for an enthusiastic and motivated PhD-student to work on an interdisciplinary research project, which combines computer science and medical neuroscience to study the topic of social cognition.

Understanding the emotional content of interactions between people in a social context can be a challenging task, both for humans and computers. From a computer science perspective, our project aims to use Neurosymbolic Artificial Intelligence to improve on the current state-of-the-art in articifial models of social cognition and emotion recognition. In Neurosymbolic AI, logic and symbolic AI methods are used to improve the performance and explainability of Artificial Neural Networks (ANNs). In collaboration with our medical project partners, we hope to leverage the results of this ANN-based study to better understand social cognition in humans, in particular people with autism and frontotemporal dementia.

For this function, our Brussels Humanities, Sciences & Engineering Campus (Elsene) will serve as your home base.
