João Graça

João Graça graduated in Informatics and Computer Science Engineering in 2002 from Instituto Superior Técnico (IST), Lisbon. He received a Masters Degree in Informatics and Computer Science Engineering in 2006, also from IST, on artificial intelligence with the development of a framework for integrating natural language tools. He was a teaching assistant in IST from (2003) to (2006) where he taught object oriented programming and compilers. He is also researcher at Spoken Language Systems Lab (L2F).

He is currently on the fourth year of his PhD program in collaboration with the University of Pennsylvania where he passed the last years as an invited student. His PhD is focused on machine learning and natural language processing. Currently he has been involved in new learning methods for unsupervised learning with domain specific constraints.
