Lorién López-Villellas

PhD Student in Computer Architecture

Computer Architecture group of Zaragoza (gaZ)
Department of Computer Science and Systems Engineering (DIIS)
University of Zaragoza (Spain)

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).
