André Martins

VP of Artificial Intelligence Research

André Martins is the VP of AI Research at Unbabel, an invited professor at Instituto Superior Técnico, and a member of the Instituto de Telecomunicações. He received his dual-degree Ph.D. in Language Technologies in 2012 from Carnegie Mellon University and the University of Lisbon. His research interests include natural language processing, machine translation, machine learning, and deep learning. He has published 30+ papers with over 1700 citations and h-index of 21 in top-tier conferences and journals (such as Computational Linguistics, JMLR, PAMI, ACL, ICML, and EMNLP), including a best paper award at the Annual Meeting of the Association for Computational Linguistics (ACL) for his work in natural language syntax. His Ph.D. dissertation has been awarded an SCS Honorable Mention at CMU. He won the Portuguese IBM Scientific Prize in 2012. André is one of the co-founders and organizers of the Lisbon Machine Learning Summer School (LxMLS).
