Professional experience |
I'm a researcher (enseignant-chercheur) at CMLA in École Normale Supérieure Paris-Saclay. My main research interest is digital image processing, especially blind noise estimation, blind denoising, compression and, in general, signal processing. I work also on satellite design (specifically, on the SMOS-HR mission), and I'm co-supervising a PhD on detection of falsifications on images and videos.
I'm part of the Editorial Board of the online journal Image Processing On Line (IPOL) and I serve as the technical director of its demo system.
The source code of the IPOL development version along with the LaTeX documentation is available at GitHub:

- Facultad de Ingeniería of Universidad de la República, Uruguay (March 18, 19, 20 and April 13, 14, 2015).

Professional Experience / Certificates
I've worked as an engineer at the following companies: Alta Tecnología Aplicada SL (AltecSoft), Sol Meliá SA (outsourcing from SM2 Baleares SA) and Juniper Consulting.
I obtained the following professional certifications from the Professional Association of Computer Science Engineers of Catalunya (COETIC):
Stay in IS/IT Professional Environment.
And these from the Coursera MOOC Deep Learning Specialization:
Improving Deep Neural Networks: Hyperparameter tuning, Regularization and Optimization
Neural Networks and Deep Learning
Structuring Machine Learning Projects
Convolutional Neural Networks
(Course final certificate)
These certificates come with a code that allows to verify them against the corresponding certification authority which issued them.
Smart Citizen project
I contributed to the Smart Citizen project by writing embedded C++ code for the firmware of the new boards (version 3). These boards contain sensors (light, sound, gas, humidity, ...) collecting data that can be shared in a queried in real time. The objective of the platform is to serve as a node for building productive open indicators and distributed tools, and thereafter the collective construction of the city for its own inhabitants.
On one hand I wrote the code to use the low-power RTX4100 WiFi module of the new sensor boards ([source code] available in GitHub). On the other hand, I wrote several improvements to the code managing the sensors ([source code] also in GitHub). A complete document with technical details of the project can be downloaded from here: [SmartCitizen Project].
I spent some days coding this [interpreter of Whitespace] (an esoteric, stack-based imperative programming language) written in Python. More info here.
Contribution to fMSX
A contributed with the idea and code of using GZIPped disk images as disks in the fMSX 3.0, an emulator of the historic 8 bits microcomputer MSX.
Notes on electronic instrumentation
I wrote this short manual on electronic instrumentation in 2002 when I was studying the degree on telecommunications. It covers briefly temperature, light, and pressure sensors and it also discusses a bit on linearization circuits (written in Spanish). Note that the website and email address in the document are no longer valid.
Proudly rejected by Google!
On 11/17/2014 I went to Google in Mountain View to make some interviews. At the end I got rejected :S, but still I'm happy because I received positive reviews, even though. It was a good experience, after all. [Picture of my guest badge].
Art and "art"
- I collaborated with Julia Puyo to build El Tiempo Real (The Real Time), an artistic reactive installation involving retrieval of twitts in real time and a mechanical device. It is exposed at the Galería Antonia Puyó from November 18, 2014 to January 15, 2015 in Zaragoza (Spain). Coverage at El Periódico de Aragón
- These are results from some of my experiments. Some of them accidentally and some others on purpose :-)
