I’m a senior researcher and lecturer in the SAFARI Research Group at ETH Zurich. I received BS and MS degrees in Telecommunication Engineering from the University of Sevilla, in 2001, and a PhD degree in Computer Science from the University of Córdoba, in 2012. Between 2005 and 2017, I was a faculty member of the University of Córdoba.  My research interests focus on GPU and heterogeneous computing, processing-in-memory, memory systems, and hardware and software acceleration of medical imaging and bioinformatics. I am the lead author of PrIM, the first publicly-available benchmark suite for a real-world processing-in-memory architecture, and Chai, a benchmark suite for heterogeneous systems with CPU/GPU/FPGA.

I’m currently a leading collaborator in the EU project BioPIM.
