Profesionaly it is better to check my LinkedIn and the most complete is my CV in pdf.
In 2002 I received my Music Examinations Degree in Piano, in the Conservatory of Valladolid (Spain). I started Telecommunications Engineering at the University of Valladolid; in 2009 I received an M.Sc. in Telecommunications Eng. (UEM, Madrid). Between 2007-2009 I lived in Sweden, and received an M.Sc. in Biomedical Engineering in 2009 (Chalmers University of Technology, Goteborg), respectively. In 2009 I spent six months as an intern in the Medical Signal Processing Group at Phillips–Aachen. where I worked with thoracic BiomImpedance in the FP7 MyHeart project.
I started my first job in a multinational called Mach Connectivity GmbH (acquired by Syniverse) as an implementation Engineer and Service Manager. I switched quickly to Biomedical again, and started a developer in eHealth, at the Zentrum für Telematik e.V. (Germany) for the design of a home dialysis infrastructure for Fresenius Medical Care.
In 2011-2012 I was a fellow at the University of Valladolid, in the Group of Biomedical Engineering in Magnetoencephalography (MEG). I held a position as a researcher in the Personal Health Informatics group in Tampere University of Technology (Finland). During this time, I collaborated at PROTOMO (Start-up incubator in Tampere), shorty at WERK1 (Start-up incubator in Munich), and some additional collaborations.
I have been working in HUAWEI developing COOL wearable prototypes, sleep algorithms, testing photoplethysmography, etc. (more details in my LinkedIn. I have been also working shortly detecting breathing using video in Neuro Events Labs Oy, cool stuff!
I have also worked in Emfit Ltd. a placed where I always wanted to work.
Currently, I am Ph.D. candidate position as a fellow at Tampere University of Technology, Finland.
Research
The topic of my doctoral thesis is centered on sleep, unobtrusive sensors and mattress sensors (such as Beddit, Emfit (eletromechanical film transducer) mattres , Fitbit, Firstbeat, raw accelerometers, etc.). The thesis proposes several state-of-the-art methods for detecting snoring, breathing efforts, breathing patterns, and heart rate detection algorithms.Research Projects
- Snoring detection
- Breathing disorders - Breathing efforts
- Heart beat detection
- Breathing detection using video and other signals
- Software I wrote to analyze EEG trends in intensive care patients, an ongoing project I am supporting a bit (2021) - When the time comes I share the Git Project.
Community projects
- locally-informed: this is the only community project I have participated back in 2020. Updating information from Finland.

Random Projects
Comsol Simulation of a Neuron
This project was part of a course I took in TUT where I simulated a neuron using the FitzHugh-Naguno model
TimeLapse with a Raspberry Pi
This is a timelapse from my house. Note how everything is already dark (winter in Finland), but also, how the goods are arriving to Sale (a supermarket). Gym (GoGo), is opening a bit before 6:00am. It was fun to set it up... I might put the code up (it is rather simple) when I find some time.You can see the super-dupper simple code in my Github. What can I say, sometimes things are that simple. The video was put together using Photoshop.
RaspFX
A great project using a Raspberry Pi (link). This is my personal webserver, hosting this project where you can upload music and add effects from PureData. The server is at home, so it might not always work (for now). This was part of a project from MediaServices with members Carita Logrén, Enrico Manuzzato, Jose Maria Perez-Macias, and Ugur Kar. I also leave some .wav files for testing since I remember they needed to have an specific sampling rate.
File1, File2, File3Watering my plants when I am away
Hoping to stop killing my plants when I go on holiday (soon to be uploaded). I basically have a basic script in a RaspBerry Pi for the lights. I bought some special medical pumps to water them and control the doses, but has proven a bit more complicated than that.
Animals
This is a game for kids. Developed in Meteor. It can be used on the phone, or iPad, as long it is not a very old iPad (iPad 1) because it becomes very slow (soon to be uploaded on a server).
Microcontroller House alarm with Keypad
Project from back in 2006 usign an Intel Microcontroller Github Link
Bus ticket Project
My first program in C++ (with my classmate Alberto Leon), we got an awesome grade! It is a bus ticket software to buy tickets to different destinations. Using Linked Lists and OO programing. Github Link
Wireless sensor monitor
Me and a colleage developed a wireless sensor monitor that is deployed in TUT, pretty cool honestly (soon to be uploaded, well maybe not so soon). Programmed in C. These were the same guys as
Real Time Control
This is a realtime control using a realtime operating system (Xenomai) me and my classmate developed (Github Link). In Chalmers, they were developing leading research to solve a problem of control over networks (nowadays everything is a network).
Csound 2003/2004
This is a super old project done in Csound about Sound of Localization,
from an old course of "Sound and Wave Engineering back in 2003/2004. It is funny
to see how much interest I still have in Sound, Biosignals...1D signals/timeseries.
Still remember Richard Boulanger!!
The project was about using Csound, documenting it. And finally we created two examples
made by ourselves.
The original site is still on! but does not work properly in moder html... so I made a
some changes and put it here.
Old page... it is here.
Sound localization
Project from Advanced Audio Processing
GitHubOther projects
I have been working on different projects as a copywriter, and also another one more dedicated to divulation.
This one is about sensors and promoting sensors. There is also a project of educating and reference material for the public based on research. Sensor Salud
This other was meant to promote what it another, but a bit abbandoned at the moment. Sleep Coaching and Research
