My first memories are settled in Spain at the age of 5 years old together with my sister and my father, starting a new life, in a new country. From this initial moment of my childhood I always remember to be curious about the natural environment that surrounds us. Thus, from these first stages of my life I remember to be interested in sciences. Once in school, this interest focused in the natural science subjects and -I cannot explain exactly why- also in maths. Likely, the interest for maths was due to the exactness that it offers to solve problems in a rigorous way, something I have always appreciated. In the secondary school, however, my interests turn into physics. It appeared as a natural way to exploit the exactness of maths to deeply understand the complexity of nature, something really elegant from my point of view. And this interest still persists.
After finishing the secondary school in 2001 I obtained the grant "Beca general (Ministerio de Educación y Cultura)" to go to the university. Between 2001 and 2005 I went to the University of Barcelona and I got the scores necessary to keep the grant and finish the degree. Is it necessary to say that I got this grant? Probably no, however, in contrast with others, I got the degree because of my effort, not the money of my parents, and I want to say that it was possible in part due to the welfare state. Neither you should misunderstand my words, I own a lot to my father and sister. Once I finished the university I had the clear idea to be a researcher, an idea that in fact, I have had with me all the time. For such a reason I started the PhD in "Advance Physics" in the University of the Barcelona and I finished in 2010. During this period of time I obtained the grants and contracts: "Fundación Pedro y Pons", "Beca de Recerca i Docència (BRD-UB)", "Marie-Curie three months fellowship" and "Formación del Profesorado Universitario (FPU-Ministerio)".
After the PhD I started to work in the B-CSI (CSIC) where still I am. Nowadays, my main interests are related with inversion methodologies applied to retrieve physical parameters of the subsurface of the Earth as well as thermohaline structures in the ocean. My work is focused in the development of mathematical and numerical methods that improves the applicability and performance of the Full-Waveform Inversion (FWI) and other seismic related methodologies.
In case you have arrived into this web page lost in the world wide web, you are not involved in seismic research, and the word FWI has woken up some interest, then, let me give a brief brief intro. The (I)inversion is because in this kind of problems we know the outputs (the response) and we have to guess inputs (the model and the excitation). Sounds cool, right? A simple case can be imagined with yourself shouting in a valley, measuring the time that the last echo arrives (the response) and then, calculating the distance to the closest mountain (the model) through this time. And the (FW)Full-Waveform it is because instead of using only the wave travel time, we can also use the amplitude and know the stiffness of the mountain. Do you want more details? Well, I think then that you need to go deeper in the physics and mathematics world and start a wonderful trip. Good luck!!!
