Sebastian is a Researcher at Facebook AI Research. He is also a Professor at University College London and an Allen Distinguished Investigator, leading the Machine Reading Lab. He has also worked in research with Andrew McCallum at UMass Amherst, Tsujii Junichi at Tokyo University and DBCLS, and Ewan Klein at the University of Edinburgh.
Sebastian works on teaching machines how to read and reason, in the intersection of Natural Language Processing (NLP) and Machine Learning. Recently, he has been tackling these problems via forms of end-to-end differentiable program interpreters as well as adversarial regularisation. He is generally interested in deep learning, good old graphical models as well as old-school symbolic AI.
