Biography

In my scientific career there are two clearly differentiated stages. During the first stage, focused on the development of my doctoral thesis, the main line of research focuses on the theme of multimedia applied to real-time tele-teaching. The result of this work was completed the doctoral thesis and published the results in several congresses and in a chapter of a book.
During this first stage I also collaborate with my main research line research group (Array Processing Group or GPA) in which it developed a prototype with electronic conformation in reception of 8 sensors that generated the patent called "Automatic Two-Dimensional Acoustic Surveillance and Monitoring System" and an magazine.
The second stage of research begins in 2003, when due to the small size of the research group it is decided to focus research efforts on a single line, abandoning the subject of tele-education. In the period 2003-2010, the development of acoustic band electronic scanning arrays and their application in surveillance systems, obtaining in 2003 the 3M Award for Technological Innovation in Security. In this period of time, the design of several prototypes was carried out and calibration algorithms, conformation in transmission and reception, electronic management of beam and follow-up, with the resources obtained in two projects financed by the programme of support to research projects of the Junta de Castilla y León, in the calls 2005 y 2007. The results of these investigations have been published in different congresses and in various magazine publications.
In 2010, the GPA began research on identifying people through acoustic images, using a multiple set of frequencies and positions, publishing the first results in the Sensors Q1 magazine article. Subsequently it has been followed deepening this line of research through the use of a set of classification based on SVM together with optimization and pre-processing techniques that have generated 2 publications in Q1 magazine.
In 2016, we are working on the use of microphones with MEM technology for the creation of new arrays with a greater number of sensors and reduced cost. A MIMECO project on the design of MEMS microphone arrays and their application to acoustic biometry and noise and vibration control in industrial machines has been achieved, the results of which have been published in 3 magazines.
At present, GPA continues with the development of scalable and low-cost acquisition systems for obtaining acoustic images through the use of MEMS microphone arrays, focusing on the application of these systems to different fields through collaborations with groups from other universities, both international and Nationals, among others: ETRO group (Free University of Brussels) for location of noise sources, AIRLAB group (Carnegie Mellon University, USA), for the integration of MEMS array on a drone for location of people in emergency situations, the Mecatran group (UC3m) for the application of acoustic arrays to dynamic control systems of vehicles and the Wood Research Group (UVa) for non destructive characterization and diagnostic of wooden structures in the cultural heritage.
