I am a PhD student in Computer Architecture in the area of Cognitive Computing on GPU Architectures. I am carrying out my doctorate, under the supervision of Prof. Antonio Gonzalez and Dr. Jose-Maria Arnau, at the Universitat Politècnica de Catalunya – BarcelonaTech (UPC), working in the Computer Architecture Department enclosed in the ARCO (Architectures and Compilers) research group.
I received a BSc in Informatics Engineering with specialization in Computer Engineering, and a MSc in Innovation and Research in Informatics with specialization in High Performance Computing, from the UPC – BarcelonaTech.
My master thesis “Characterization of Speech Recognition Systems on GPU Architectures”, was done under the supervision of Prof. Antonio Gonzalez and Dr. Jose-Maria Arnau.
The research for my doctorate focuses on the area of Cognitive Computing, in particular Speech Recognition, as well as Graph Processing on GPU Architectures. My objective is to propose and evaluate architectural extensions to GPU Architectures with the goal to improve energy-efficiency and performance which will enable and empower more precise and capable Automatic Speech Recognition systems (ASR) and improved performance of graph processing algorithms. My current focus is on the improvement of the memory system utilization under graph exploration on GPU architectures.
Topics: Computer Architecture, Graph Algorithms, Stream Compaction, Speech Recognition, ASR, Viterbi, GPU Architectures, Energy-Efficency.
