Dr. Gioiosa is a research scientist at Barcelona Supercomputing Center (BSC) in the Computer Architecture / Operating System interaction group since September 2009. 
Roberto received his Ph.D. on "High performance computing clusters" from the University of Rome "Tor Vergata" in 2006. Prior to coming to BSC, he was graduate student at Los Alamos National Laboratory (LANL) from April 2004 to June 2005, working on High Performance Computing (fault tolerance and performance analysis) in the context of the PERCS project. Roberto started at BSC as post-doc in 2006; at BSC he worked on Operating System (mainly Linux) for High Performance Computing Clusters and optimization for future processor architectures. From September 2008 to September 2009 he was post-doc at IBM TJ Watson Research center, in the BlueGene system software group, where he worked on the operating system for next generation of supercomputers (mainly CNK). 
In Fall '09/Winter '10, Roberto visited Prof. Michael L. Scott at the University of Rochester (NY). During his visit, Roberto worked on characterization of resilient memory usage and GPU scheduling for multimedia applications.

Since 2006 Roberto has also been an external collaborator of the System Programming Research Group at the University of Rome "Tor Vergata".
