Maurizio “Titto” Patrignani http://patrignani.dia.uniroma3.it • 2001: Ph.D. in Computer Science from the University of Rome “La Sapienza” – Thesis: Visualization of Large Graphs • 2006: Associate Professor at Roma Tre University • Research fields – Computer Networks, – Information Visualization, and – Computational Geometry
Titto’s research • Computer networks – BGPlay: visualizing the evolution of interdomain routing – computing the type of relationships between autonomous systems • Information visualization – clustered planarity, partially embedded planar graphs, minimum-depth embeddings, (x,y)-graphs, etc – three-dimensional orthogonal graph drawing • Computational geometry – NP-hardness of some graph drawing related problems
