I am Full Professor in the Computer Engineering Department at the University of Murcia, Spain. Funded by the Spanish government to conduct the PhD studies I received the PhD in computer science from the University of Murcia in 2009. I held postdoctoral positions at the Technical University of Valencia and at Uppsala University. I received an European Research Council (ERC) Consolidator Grant in 2018 to improve the performance of multicore architectures. Working on cache coherence, memory hierarchy designs, memory consistency, and processor microarchitecture, I have co-authored more than 100 peer-reviewed articles. I have been inducted into the ISCA Hall of Fame and MICRO Hall of Fame. I am IEEE Senior member.
