I am a mathematician that finds in engineering the source of problems to solve or an engineer that uses mathematics to think about technical problems. My ambition is to pursue, in Academia, Industry, or both, this interplay between mathematics and engineering.

Some quotes I like

“Everything should be made as simple as possible, but not simpler.” Albert Einstein
“When solving a problem, try to avoid solving a more general (harder) problem as intermediate step.” Vladimir Vapnik
“You don’t really understand something unless you can explain it to your grandmother.” Albert Einstein
“If you’re not failing every now and again, it’s a sign you’re not doing anything very innovative.” Woody Allen.
“Quality means doing it right when no one is looking.” Henry Ford.
“Anyone can make the simple complicated. Creativity is making the complicated simple.” Charles Mingus.
“Mathematics is a war against inconsistency.” Robert Rosen.
“The proof of the pudding is in the eating.”
“A bad example may be better than a good theorem.” G. Ancoechea.
“There is nothing in the intellect that was not first in the senses.” Aristotle.

Short Bio (complete cv)

I received my Ph.D. in mathematics and my Ph.D. in telecommunications engineering from the University of Valladolid, Spain, both with the highest honors in 2009 and 2011, respectively.

I have been a Staff Engineer at Qualcomm Corporate Research and Development since Mar 2014. Prior to joining Qualcomm, I was a Postdoctoral Fellow and Associate in the Laboratory for Information and Decision Systems (LIDS) at the Massachusetts Institute of Technology (MIT) from Sep 2009 to Mar 2014 . I previously worked from 2006 to 2009 as a researcher and project manager in a Spanish technological center as well as a junior lecturer in the University of Valladolid. My general research interest is the application of mathematics to solve engineering problems, currently my work is primarily focused on statistical signal processing, machine learning, and data science.

I am Associate Editor for the IEEE Communications Letters, and have served as Co-chair for the Symposiums on Wireless Communications at the 2014 IEEE Global Communications Conference (Globecom) and at the 2015 IEEE International Conference on Communications (ICC). I have been a member of the Technical Program Committee (TPC) for numerous conferences including the IEEE Globecom in 2010-2015, IEEE ICC in 2013-2015, IEEE VTC in 2012 and 2015, and ICUWB in 2011, and 2013-2015. I have received the Best Student Prize in Telecommunications Technical Engineering from University of Valladolid in 2006, the Best Doctorate Thesis Award from University of Valladolid in 2011, and the Young Scientist Prize from the Union Radio-Scientifique Internationale (URSI) Symposium in 2007. My papers received the IEEE Communications Society Fred W. Ellersick Prize in 2012, and Best Paper Awards from the IEEE ICC in 2013, the IEEE ICUWB in 2011, and the IEEE Globecom in 2011.
