I am a scientist at Facebook Artificial Intelligence Research (FAIR). I am committed to building an axiological artificial intelligence to improve our society, particularly the lives of those who need it most. My current research efforts focus on essential prerequisites of such AI: Fairness, Transparency, and Reliability. The Newscientist and the MIT Technology Review have highlighted our recent work in this area. I was born and raised in the beautiful Senegal (you should visit!), where I studied maths and physics at Universite Gaston Berger. Later, I completed a Ph.D. in machine learning at Universite Pierre et Marie Curie in Paris (France).
