I started my research activities with a PhD dissertation at the UZ related to the implementation of Petri Nets, inside the field of Discrete Event Systems, proposing Linear Enabling Functions (LEFs), a fast way to characterize transition firing, extensively leveraged later, with a side contribution on the modelling of a pipelined architecture. I then joined the Computer Architecture Group of the Univ. of Zaragoza (gaZ), where I started contributing in hardware data prefetching techniques, co-advising a PhD student, with results that led to the Best Paper Award in the 1st. Data Prefetching Championship, held by Intel in Raleigh, NC, USA, 2009.
I have also collaborated with the MASC Lab (UCSC, CA USA) on memory hierarchy optimizations for GPGPUs, also exploiting Voltage Stacking techniques for Near-Threshold Computing (NTC). This has resulted in a number of quality papers (ISLPED 2013, TACO 2016, IEEE TVLSI 2018), co-advising a PhD student at the Univ. of California Santa Cruz.
I am currently collaborating with the Advanced Research Center (CINVESTAV) in Guadalajara, Mexico, related to thermal-aware real-time scheduling in MPSoCs, targeting the accomplishment of time, thermal and energy constraints while reducing size, weight and power in aerospace, satellite and automotive embedded systems. I have supervised the PhD. Thesis of Gaddiel Desirena, and I am the current co-advisor of the PhD student Laura Rubio. We have so far achieved promising results presented and published in WODES 2016, WODES 2018, TECS 2019 and DEDS 2019. I also keep collaborating in other research lines of the gaZ associated to performance evaluation, efficient software and hardware implementation of algorithms and heuristics employed in Artificial Intelligence (vid. e.g. IEEE T-G 2017).
I have been collaborating with companies for a long time, mostly solving complex specific problems related to Linux security, poor system performance, or deadline misses in hard real-time systems. In most cases, I have often counted on senior undergrads, MSc or PhD students who have seamlessly joined the company or jumped to others related to the field. I have led formal and informal agreements with international companies like Infineon and Intel Mobile Systems (Munich, Germany), ARM (Cambridge, UK) or BSH Spain (Zaragoza), besides a number of smaller local companies that benefit from this type of collaboration.
Part of my research has been related to a multidisciplinary project in Geology – Geophysics and Computing, where I envisioned and developed two successful approaches based on laboratory and mathematical models, which complemented the initial single research avenue based on natural models, allowing the validation of restitution methods used for gas, oil and CO2 natural reservoir exploration. This work led to four articles in renowned journals. I also co-advised an MSc and PhD student. Her MSc thesis was awarded with the Premio García Siñériz to the best MSc contribution in Geophysics in Latin-America and Spain, and a Midland Valley Award.
I have been teaching courses on Computer Architecture, Operating Systems and Embedded Systems since 1994, at both the undergrad and MSc level, always at the UZ. I was a member of the Executive Board (Consejo de Gobierno) and Senate (Claustro) of the institution, and held the Vice-Chair position of my Department from 2012 to 2016.
