Previous Research

I have worked developing new methods for low- and mid-level vision operators for their implementation in specific-purpose architectures such as FPGAs. I joined the University of Granada in 2007 to obtain my PhD, where my advisors where Prof. Eduardo Ros and Dr. Javier Diaz. I worked on  the EU project DRIVSCO Learning to emulate perception-action cycles in a driving school scenario from 2007-2010.  In the framework of this project I visited the University of Genoa (2010) under the direction of Prof. Silvio Sabatini. After 2011, I focused on the role that diverse low-level vision engines play in deploying visual attention. The released hardware designs and implementations of all this work can be found at the CERN Open Hardware Repository. I took part of the Telluride Workshop on Neuromorphic Cognition Engineering (Colorado, USA) in 2011. Then, I visited Prof. Kwabena Boahen lab at Stanford University in 2012 designing and developing the final architecture for a visual attention system with top-down modulation. This was the main contribution of my Thesis presented that year. In 2013, I collaborated with the EU project TOMSY Topology based motion synthesis for dextereous manipulation. 

Current Research
I obtained an IOF EU Post-Doc Marie Curie Fellowship in 2013 and started working for the Computer Vision Lab at University of Maryland (Maryland, USA) under the supervision of Prof. Yiannis Aloimonos and Dr. Cornelia Fermuller. During this time I have focused on building new models for estimation of motion, 3D reconstructions, or object segmentation for asynchronous frame free sensors. Here you can find my CV and my Google Scholar profile.
