Research

My research work focuses on data-analytics and applications of machine learning towards efficient computing, quality of service on web-services, and autonomic Cloud applications management. I have been working at the LARCA Research Group (Laboratori d'Algorí­smica Relacional, Complexitat i Aprenentatge) at LSI-UPC, at the HPC-Autonomic (High Performance Computing Group) at DAC-UPC, at the Autonomic Business Systems Research Group also leader of the Data-Centric Computing Research Group at Barcelona Supercomputing Center (BSC). Currently managing the Computing Resources Orchestration and Management for/through AI Research Group at UPC + BSC.
