Josep Valls-Vargas

Josep Valls-VargasWelcome to my home page.

I am a PhD candidate in the Department of Computer Science at Drexel University under the supervision of Dr. Santiago Ontañón Villar and Dr. Jichen Zhu. My research is focused around Artificial Intelligence (AI) and the particular application domain of digital entertainment. I am interested in topics like Natural Language Understanding, Computational Narrative, Drama/Experience Management and Procedural Content Generation.

I received a B.S. in Computer Science from Universitat Autònoma de Barcelona in 2010 and a M.S. in Artificial Intelligence and Computer Vision from UAB/IIIA-CSIC in 2011.
