Biography

Jean Kossaifi is a Research Scientist at the Samsung AI Center in Cambridge, and a PostDoc in the Department of Computing, Imperial College London. His current position follows the completion of a PhD in Machine Learning in Imperial College London,  under Professor Maja Pantic's supervision. He also obtained an MSc in Advanced Computing, with Distinction, from Imperial College London, UK. In addition, Jean holds a French Engineering Diploma/MSc in applied mathematics, finance and computing, obtained in parallel with a BSc in Advanced Mathematics.

His research interests are primarily focused on the areas of machine learning, computer vision and pattern recognition, with applications in human-computer interaction, automatic non-verbal behaviour analysis and emotion recognition. He is particularly interested in tensor methods and how to combine these with deep learning.
