I currently work as a senior research scientist at Intel Labs, Barcelona.

My PhD thesis was on Distributed Transactional Memory which resulted in the development of DiSTM [1],[2], a distributed software transactional memory system which applies memory transactions on clustered Java Virtual Machines.

Research Interests

  • Parallel/Distributed programming languages
  • CMP Architectures
  • Transactional Memory (Hardware/Software)
  • Garbage Collection: Summer (2008) Internship at Sun Microsystems Labs as a member of the Maxine project.
  • Java

    In the past I was working on parallel compilation (Jikes RVM) and adaptive optimization techniques.

    Finally, I work on establishing formal methods on Pro Evolution gameplay :-).
