About me

I am currently a Postdoctoral Research Fellow at the Computational Media Innovation Center (CMIC) from the Victoria University Wellington and a Researcher at INESC-ID Lisboa. I received my PhD in Information Systems and Computer Engineering from Instituto Superior Técnico, a Msc in Informatics from Pontificia Universidade Católica do Rio de Janeiro (PUC-Rio) and a Bsc in Computer Science from Federal University of Paraíba (UFPB), Brazil. At INESC-ID I joined the Visualization and Intelligent Multimodal Interfaces Group at INESC-ID Lisbon. During my Msc I was part of the Virtual Reality and Digital Entertainment Group at Tecgraf Institute/PUC-Rio, where I developed Virtual Reality applications for the oil and gas industry. My main interests include Virtual Reality, 3D User Interfaces, Augmented Reality and Human Computer Interaction.
