Short Bio
Alfredo Ferreira is an Assistant Professor at the Instituto Superior Técnico, University of Lisbon. He received his Ph.D. (2009), MSc (2005) and BS (2002) degrees in Information Systems and Computer Science from Technical University of Lisbon. He is simultaneously a researcher of the Visualization and Intelligent Multimodal Interfaces Group at INESC-ID Lisboa. He works on multimodal and natural interfaces, virtual and augmented reality and 3D object retrieval. He participated in the SmartSketches, Eurotooling21, and Maximus EC funded projects. His involvement in these projects focused on natural user interfaces and multi-user, large-scale and multi-display environments. He participated in the nationally funded DecorAR, MIVis and CEDAR projects and led the 3dORuS project. He was a member of the organizing committees of INTERACT 2011 and Eurographics 2016 conferences and is general chair of SMI 2018 symposium and Eurovis 2019 conference. Alfredo Ferreira is a member of ACM, IEEE, and Eurographics. He is also the chairman of the fiscal council of the Grupo Português de Computação Gráfica.
