Juan Carlos Díaz Martín

Biography

Graduated in Computer Science in 1989 and Doctor in Computer Science in 1994, both degrees from the Polytechnic University of Madrid. He was a Research Fellow at the Environmental and Technological Energy Research Center (CIEMAT) in Madrid and later a Senior Research Technician. There I carried out the research tasks leading to obtaining the Doctoral Thesis in 1994, on automatic analysis of radiation spectra using Neural Networks. I began my academic career at the University of Extremadura in October 1994. In 1996 I won a position as an Associate Professor.

Currently assigned to the Department of Computer and Communications Technology at the Polytechnic School of the University of Extremadura, in Cáceres, I have taught subjects on office automation, multicore programming, real-time systems, operating systems, distributed operating systems and operating system design. FromFebruary 2013 to october 2019, I have been the coordinator of a Joint Training Program that brings together three degrees: the Master in Telecommunications Engineering, the Master in Computer Engineering and the Master in ICT Management. That time I was a member of the External internship committee of the Polytechnic School and the center's Quality Assurance committee.

I am a founding partner of Sicubo S.L., the first spin-off company of the University of Extremadura, where I contributed my experience in execution cores in the development of voice recognition systems on distributed DSP platforms.
I have carried out two research stays of three and two months respectively at the Department of Electrical and Electronic Engineering of the University of Bristol under the supervision of Doctor Naim Dahnoun, a recognized expert in the efficient implementation of signal processing algorithms in DSP processors. I completed another two-month stay at the HLRS, the supercomputing center of the University of Stuttgart under the HPC-Europa2 Transnational Access Program under the supervision of Dr. Rolf Rabenseifner.

I have been a reviewer for the magazine “The Computer Journal” and a member of the scientific committee of the spanish Embedded Computing Conference. I was involved in the European network e-Cost IC1305 NESUS action (NETwork for Sustainable UltraScale Computing) and in the national network CAPAP-H5 (High Performance Computing Network on Heterogeneous Parallel Architectures).

In the past I worked on the application of geometric methods to determine the roots of high-degree polynomials, and their application to speech modeling and recognition. In this area, I am co-author of Contour, a method capable of accurately and efficiently determining the roots of poorly conditioned polynomials of up to degree 500, an unprecedented figure compared to traditional iterative methods .I develop and maintain a thread-based implementation of the MPI standard in multicore environments called AzequiaMPI .

I am co-author of more than 70 articles, nine of them Q1. I have participated in more than 20 regional and national research projects. In particular, I was principal researcher of the Hesperia project (Homeland Security Technologies for the Security in Public Spaces and Infrastructures) of the CENIT Ingenio2005 program of the CDTI, endowed with 388,008.40 euros under a contract from the company Tecnobit. In the project, a signal processing engine was developed based on a Sundance DSP distributed platform and a Wifi positioning system based on a Bayesian inference engine.

I done work on modeling communications performance in HPC environments, in which I am co-author of the tau-Lop communication performance model. My current research interests is high performance computing (HPC) and the simulation of networks this area using SimGrid.
