imXPAD, France2013 - 2016
As software manager, I was in charge of the research and software development for X-photon counting detectors. The detectors provide fast communication with frame rates upto of 900 images/s, while delivering quasi-noiseless imaging. We collaborate with the LIMA and EPICS community to provide an imXPAD open source plugin to incorporate our detectors to the infrastructure of synchrotron facilities LIMA imxpad camera.

Centre de Physique des Particules de Marseille (CPPM), France2010 - 2012
In collaboration with the openGATE community to generate the Monte-Carlo simulation code that runs in NVIDIA graphics cards (GPU). The aim of my work was to accelerate simulations in order to make them practically useful. Using Intel's processors (CPU), one single CT (Computed Tomography) simulation can take up to 17 days to be performed. By using our code running in graphic cards, the same simulation only takes around two hours.

The subject of my Ph.D. thesis was the research and implementation of faster and more accurate ways to estimate image quality in digital mammography Objective but fast, and subjective but slow image quality assessments were combined in order to make the procedure faster and more accurate. The mixture of the two approaches was performed using analytic simulations of an image quality phantom (CDMAM). The simulated images of this phantom were automatically evaluated to obtain the lesion (tumor) detection index of the mammography device.

Centre Européen de Recherche en Imagerie Médical (CERIMED), France2013 - 2013
My job was to integrate 3D infrared tracking system into ClearPEM machine. This machine is a PET (Positron Emission Tomography) device for breast scans. The integration of 3D tracking system allows to register PET and ultrasound volumes in order to improve breast cancer diagnosis.

My research focus was the optimisation of the CEDM technique (Contrast-medium-Enhanced Digital subtraction in Mammography) for the early identification of breast cancer. The basic idea was to obtain mammographic images pre and post-injection of a contrast medium. After the acquisition, the images were subtracted from each other. The resulting image showed precisely the position of the tumor as the anatomical breast background was "vanished". My work showed the efficiency of the results when the subtracted images were acquired using the same X-ray exposition energy.

Alarmas Lago, Mexico2004 - 2005
I automated a call reception server of a security call-center company. The system consists on a Microsoft Access database interconnected to a phone call receptor via a RS232 cable. Eöergencies calls are registered automatically and the client information is automatically shown to the operator which is in charge to react accorantly depending on the kind of emergency. The software was created in 2004, updated in 2010 & 2020 and it is still being used in the company.
Happy Client!

Development of a system intended to help people with visual impairment to travel in urban zones without external assistance. The system includes the advantages of a GPS (Global Positioning System) navigation system, and a PDA (Personal Digital Assistant) commonly known at that time as handheld. The user interacts with the system via voice, for both giving instructions and receiving information.
