I’m an associate professor at the University of Amsterdam, where I lead the theoretical computer science research unit<\/a> of the Institute for Logic, Language and Computation (ILLC)<\/a>.<\/p>\n\n\n\n

My research spans different applications of logic in computer science and AI, with a particular focus on data management, knowledge representation, and machine learning.<\/p>\n\n\n\n

In the past, I worked at INRIA, UC Santa Cruz, Stanford, LogicBlox, and Google.<\/p>\n<\/div>\n\n\n\n
