Jesús Alastruey Benedé received the Telecommunication Engineering degree and the PhD degree from the Universidad de Zaragoza (UNIZAR, 1997 and 2009). Since 1999 he has been a lecturer in the Computer Architecture and Technology (CAT) area at the Departamento de Informática e Ingeniería de Sistemas of UNIZAR, where he is an Associate Professor (Profesor Titular de Universidad). He carried out his doctoral thesis between 2003 and 2009 under the supervision of Teresa Monreal, Víctor Viñals and Mateo Valero, on topics related to register file management.

Professor Alastruey is a member of the Computer Architecture research group at the Universidad de Zaragoza (gaZ), which is part of the Aragón Institute for Engineering Research (I3A). The gaZ group participates in the European network of excellence HiPEAC and is recognized as a reference research group by the Government of Aragón.

Professor Alastruey has supervised four doctoral theses. He has participated as a researcher in eight consecutive projects of the Spanish National R&D Plan. Most of his research work is related to the memory hierarchy (register file, hardware data prefetching, cache space and memory bandwidth control mechanisms, caches operating at near-threshold voltages) and to application optimization (genomic analysis and molecular dynamics). He has published in high-impact journals and prestigious conferences in the field, and his work has had an impact on industry: six of his papers have been cited by 22 patents and patent applications from companies such as IBM, ARM, Qualcomm, AMD, Synopsys, Google and Ddaim. His recent work includes Berti, one of the state-of-the-art data prefetchers since 2022; the characterization of the memory hierarchy of the Intel Xeon Skylake processor (non-inclusive LLC), cited on the SPEC CPU 2017 website and partially reproduced in the seventh edition of the book "Computer Architecture: A Quantitative Approach" by Hennessy, Patterson and Kozyrakis; and the characterization of the memory hierarchy of the AMD EPYC Rome processor (clustered LLC), an updated version of which (AMD EPYC Milan) has been partially incorporated into the second edition of the book "Performance Analysis and Tuning on Modern CPUs" by Denis Bakhvalov.

Professor Alastruey has taught 20 different courses in the CAT area in Bachelor's, Engineering, Postgraduate and Master's programs. He has supervised (as director or academic tutor) 5 Master's theses, 29 Engineering final projects (PFC) and 6 Bachelor's theses.

In university management, since 2025 he has been Deputy to the Director of the School of Engineering and Architecture (EINA) for Digitalization. He represents the teaching and research staff on the School Board and on the Quality Assurance Committee for the EINA Master's programs.

Regarding work with companies, between 2004 and 2017 he collaborated with TAFYESA on the development of remote infrastructure management systems. This collaboration resulted in automation, communication and remote management products deployed in TAFYESA installations for companies and institutions all over the world. Within this framework, he has provided consultancy for grant applications in competitive calls; most notably, the fourth-best rating (180 out of 200 points) among 286 applications in the 2017 call of the Aragón program of Aid to Industry and SMEs (PAIP).
