Andrea Torsello received his PhD in computer science at the University of York, UK, and is currently an assistant professor at Ca' Foscari University of Venice, Italy. His research interests are in the areas of computer vision and pattern recognition, in particular, the interplay between stochastic and structural approaches as well as game-theoretic models. Recently, he co-edited a special issue of Pattern Recognition on "Similarity-based pattern recognition." Dr. Torsello has published around 40 technical papers in refereed journals and conference proceedings and has been in the program committees of various international conferences and workshops. He will co-chair the next edition of GbR, a well-established IAPR workshop on Graph-based methods in Pattern Recognition, to be held in Venice in 2009. Starting from November 2007 he will hold a visiting research position at the Information Technology Faculty of Monash University, Australia.
