Professor Libal joined The American University of Paris in 2016. His previous positions were in Inria (French Institute for Research in Computer Science and Automation) and Ecole Polytechnique.

After obtaining his BSc in Computer Science and Mathematics from the Hebrew University of Jerusalem in 2001, Libal has spend several years working as a Java team leader for the start-up company Quigo. In 2008 he obtained a double MSc degree in Computational Logic from the technical universities of Madrid, Spain and Vienna, Austria as an Erasmus Mundus scholarship holder. In 2012 he obtained his PhD from the technical university of Vienna with a thesis on Higher-order Automated Deduction.

He is a member of the Association for Automated Reasoning. Libal's research is mainly focused on Higher-order Automated Deduction and especially on variants of higher-order unification. Other topics include Formal Verification and Proof Certification of classic and modal logics. During his professional career, Libal has conducted both theoretical research and implemented tools and software.
