My research centers on accelerating scientific applications by developing novel algorithms and optimizing the usage of hardware resources, primarily focusing on vectorization and parallelism. Currently, I am working on a new algorithm for constrained Molecular Dynamics alongside the porting and acceleration of genomics applications on Arm and RISC-V platforms.
I collaborate with the High-Performance Domain-Specific Architectures group at the Barcelona Supercomputing Center (BSC).
