I am an Associate Professor at the Computing Systems Department (DSI) of the University of Castilla-La Mancha (UCLM), Spain.

In November 2006, I joined the research group on high-performance networks and architectures (RAAP) at UCLM under the supervision of Profs. Francisco J. Quiles and Pedro J. Garcia. In December 2011, I defended my Ph.D. dissertation. I worked as a postdoc in the RAAP group until the end of 2013, with fruitful international collaborations during my research stays in Simula Labs, Oslo (Norway), and Heidelberg University (Germany).

In January 2014, I moved to the industry as a Senior Ph.D. engineer at Oracle Corporation, Oslo (Norway), where I contributed to developing the Linux host stack for Oracle’s InfiniBand EDR (100 Gb/s) technology. In this project, I applied my background in interconnection networks to the design and implementation of innovative and efficient solutions, which were included in a commercial product. In 2015, I moved to the Technical University of Valencia (UPV) as a postdoc researcher, under the supervision of Prof. Jose Duato, with a competitive grant Juan de la Cierva – call of 2014 (8 grants were awarded from 105 applications, and I was in the 6th position, i.e. 7,5% of acceptance rate). In December 2015, I came back to the RAAP group, UCLM, with a tenure-track research associate position co-funded by UCLM’s own research program and European FSE Funds (20 grants were awarded among 89 applications, and I was in the 2nd position, i.e., 22% of acceptance rate). My research interests include high-performance interconnection networks for high-performance computer clusters and data centers, network topologies, routing algorithms, and congestion management.

Although I usually collaborate with my Ph.D. advisors, I conduct independent research in interconnect technologies for supercomputers and centers to transfer the developed ideas to the Industry. On this matter, I have participated in meetings of the IEEE 802.1 TSN working group in Pittsburgh, USA (May 2018), and San Diego, USA (July 2018), giving two conferences to support the IEEE 802.1Qcz standardization amendment (Congestion Isolation for Lossless Ethernet Networks), which was finally accepted to be included in the 802.1Q Standard. I have participated in more than 20 research projects funded by Regional, National, and International funds, and I have also collaborated in R&D agreements with private companies. Moreover, I have been the Principal Investigator of one Regional Project funded by “Excma. Diputación de Albacete” (the call was competitive) and two National projects, one of them funded by the Spanish Ministry of Science under a competitive call (no data related with acceptance rate is provided) and other funded by Fundación BBVA Becas Leonardo (success rate: 6,8% – 5 grants were awarded in the IT panel from 73 applications). I have supervised three doctoral theses whose Ph.D. students are now in important companies. I currently supervise five PhD students. I have also supervised 10 MSc theses and 15 final degree projects.

I have published more than 50 articles in peer-reviewed journals and conferences. I am also co-inventor of three national patents (one with the previous examination). Regarding other research collaborations, I maintain collaborations with UPV (Profs. Enrique Quintana, Maria Gómez and Julio Sahuquillo), Simula Labs (Profs. Olav Lysne and Tor Skeie), Ruprecht-Karls University of Heidelberg (Prof. Holger Fröning), ETH Zürich (Prof. Torsten Hoefler) and the ATLAS experiment at CERN (Wainer Vandelli). I also collaborate with the industry, especially with companies such as Huawei, Atos-BULL, Mellanox, and Intel. I have participated in the organization of several scientific meetings, such as the HiPINEB workshop (5 editions), meetings of the Spanish CAPAP-H network on heterogeneous and distributed computing, Publicity chair in WOSSS workshop (3 editions) and participated with several invited talks and keynotes in HPC-AC (2013), CTIC-UNI (2015), PDP (2022), IEEE802.1 (2019), IETF 105 (2019), NENDICA (2019), Huawei international DCN workshop (2019), HiPEAC (3-SEA, RED-SEA and 10 HPC-JU workshops in January 2024), and tutorials on the VEF traces framework given to different EU projects (RED-SEA, IO-SEA and DEEP-SEA). I have also served as a technical program committee member and reviewer in international conferences, such as HPCA (2024), IEEE ICPP (2017), IEEE CCGrid (2018, 2019), IEEE HoTI (2016, 2017, 2019,2020,2021,2022 and 2023), IEEE HPCS (2016, 2017, 2018), and in international journals, such as Elsevier JPDC, IEEE TPDS, IEEE Micro, Journal of Supercomputing, and CAL.
