Welcome

I am a research scientist at NVIDIA Research, in the Programming Models Group. In the past, I worked at the Barcelona Supercomputer Center in the heterogeneous architecture group from the Computer Systems department. I have also worked as a post-doc researcher in the IMPACT Research Group in the University of Illinois, and as lecturer in the Computer Architecture Department at the Universitat Politecnica de Catalunya.

My current research focuses on low-power high performance computer architectures, and system software for parallel and heterogeneous architectures. Previously, I was involved in the Mont-Blanc project, that aims to build the next generation of supercomputers using chips from the mobile market.
