I appreciate the complex and refined tasks the brain performs: from controlling our breath to cognition or perception. I enjoy theory: how to to describe the beauty of a mathematical proof? I also like to work with computers: developing computer models that mimic natural processes, solving optimization problems, programming web applications …

My current research is centered in developing computational models of the visual system. Modeling the visual system is an activity that combines the research interests stated above. I observe the brain closely in order to build physiologically realistic models. I try to use theory skillfully to build generic models. I implement the models in computer programs. Finally, after I have observed the brain, used good theory and implemented efficient computer programs I need to go back to nature and check whether the implemented models explain real data.
