Researcher at Albatroz Engenharia (2012&2013, high power line inspection company, developed pont-cloud shape-analysis classifiers, and new segmentation algorithms for out-of-core LIDAR data).
Collaborator (>2012) in a novel minimally invasive surgery system with Hospital Dr. José Maria Grande of Portalegre and Centro de Cirugía de Mínima Invasión Jesús Usón(Spain).
CIAUD research group member (>= December, 2015), aiming to develop tools that aid the modeling process of architectural documents from point-cloud data. Other interests include visualization, meshing, registration, HDR, shape-analysis and navigation.
Reviewer for the International Journal on Remote Sensing, Sensors, Winter School of Computer Graphics.
Co-author of 28 peer-review articles with contributions in several areas (e.g: mesh cleaning, level of detail, interactive visualization, compression, animation, collision detection, image-based rendering, cultural heritage, GIS, hydrography, photogrammetry, computational geometry, computer assisted surgery, physiotherapy tools, navigation, augmented reality, mobile phone development).
Was awarded with his former student João Tavares, ex aequo the 1st prize of the “Ser-Capaz 2012” (nation-wide competition) by Associação Salvador for a novel Physiotherapy tool.
