My present research focuses on the following lines: improvement of the efficiency of the SLLC in terms of area and energy consumption (near threshold computing), and application optimization (efficient molecular dynamics simulations and genomic applications).
Currently collaborating with the Computer Architecture - Operating System Interface (CAOS) group at the Barcelona Supercomputing Center (BSC).
