I began my research career at the University of Zaragoza (UZ) with a PhD dissertation in Discrete Event Systems, where I proposed Linear Enabling Functions (LEFs), an efficient method to characterize transition firing in Petri Nets, alongside contributions to pipelined architecture modeling.
After joining the Computer Architecture Group at UZ (gaZ), I transitioned to high-performance computer architecture, contributing to hardware prefetching techniques and co-advising a PhD student. Our work earned the Best Paper Award at the 1st Data Prefetching Championship, organized by Intel in Raleigh, NC, in 2009.
My current research centers on routing, scheduling, and fault tolerance in Time-Sensitive Networks (TSN, IEEE 802.1Q). I co-advise a PhD student, an MSc student, and several undergraduate researchers, leading the development of a physical TSN testbench for experimental validation and industry transfer. Early results have been published (WODES 2024, IEEE Access 2024, TSN/A 2024, ECRTS-IC 2025), with further advancements underway.
Previously, I pioneered thermal-aware real-time scheduling techniques for MPSoCs, optimizing for timing, thermal, and energy constraints in embedded aerospace, satellite, and automotive systems. I supervised two PhD theses in this field, culminating in a novel methodology for designing low-energy, thermally stable cyclic executives, with adaptive runtime control for system disturbances. This line of research benefited from a collaboration with CINVESTAV – Guadalajara (Mexico) on the application of control engineering techniques.
I have also collaborated with Prof. José Renau at the MASC Lab (University of California, Santa Cruz) on memory hierarchy optimization and Near-Threshold Computing (NTC) for GPGPUs, resulting in high-impact publications (ISLPED 2013, ACM TACO 2016, IEEE TVLSI 2018) and the co-advising of a PhD student at UCSC.
Beyond hardware architecture, I contributed to the efficient software and hardware implementation of AI algorithms, publishing in venues such as IEEE Transactions on Games (2017).
Throughout my career, I have maintained a strong collaboration with industry, solving critical problems in Linux security, system performance, and hard real-time deadline management. Many of my students have successfully transitioned into these companies. I have led collaborations with global companies such as Infineon and Intel, as well as several regional firms.
In addition, I joined a multidisciplinary research project bridging Geology, Geophysics, and Computing, developing laboratory and mathematical modeling techniques to validate reservoir restitution methods. I co advised a PhD student, and the work produced four articles in leading journals and the award-winning MSc thesis recipient of the Premio García Siñériz and a Midland Valley Award.
Since 1994, I have taught Computer Architecture, Operating Systems, and Embedded Systems at undergraduate and MSc levels at UZ. I have also held academic leadership roles, serving on the Executive Board (Consejo de Gobierno), the University Senate (Claustro), and as Vice-Chair of my department (2012–2016).
