My BSc final work was an immersion in Augmented Reality: Smartphone system for localization and orientation inside buildings. Great, isn't it?

I worked one year at Siemens Networks - Key Performance Indicators daily analysis and troubleshooting.

Two years at Institute for Systems and Robotics - Computer Vision (highways surveillance - Brisa S.A.)

Five years at Telecommunications Institute - Microwaves Lab (having fun doing a lot of things...). In the meantime I did my master (MSc), playing with a robotic arm and a Vector Network Analyser. Well, I designed and implemented a Near Field Scanner for the Lab.

Pretty thing, I say... and it is. Now we have this tool to really see the electromagnetic field in the surface of some structure (antennas, metamaterials prototypes, etc.)

I' am also an enthusiastic of RFID systems!

In 2013 I learned about crystallography attending freely a discipline called Ceramic Sensors of Semiconductor Oxides.

I have fabricated humidity sensors based on WO3 and TiO2 and with ZnO as dopant. Just cooking ... and then characterize the samples through a complex impedance analyzer.

I did a few of parallel computing in Computer Vision Field. I was engaged in a project for 3D Reconstruction of Urban Scenarios.

In 2014 summer I drove a "Google Street View" like car... with a set of cameras on it, GPS on board, etc, to collect some datasets of stereo pairs of images (video stream) in a middle sized city (Coimbra).

In Jan 2015 I started a Ph.D program in Physical Engineering. I'm working with medical cameras for imaging, namely scintillation cameras for nuclear medicine. A patient has to take a radiopharmaceutical that emits radiation from inside the body. Scintillation cameras are able at detecting the position inside the body from where radiation come from, which could mean, for instance, the region of an inflammation or even an unhealthy tissue.
