   University of Barcelona




I graduated in Physics at the University of Barcelona in 1997, and undertook my Ph.D. thesis in the same University, at the Department of Physics. My research focused on experimental studies of oil-air interfaces in porous media. The research in Barcelona was combined with stays at the University of Massachusetts and the University of Oslo. Due to my interest in multidisciplinary research, during the last two years of my thesis I attended a number of summer schools and workshops in biophysics.


I started my first postdoctoral stay upon completion of my Ph.D. thesis in early 2003. Due to my interest in biophysics I joined the European Training Network PHYNECS (Physics of Non-equilibrium Complex Systems) and for two years I studied pattern formation in multicellular organisms. The research, developed at the University of Bayreuth (Germany), focused on the regeneration process of the freshwater polyp Hydra. I gained experience in a variety of experimental techniques, and fruitfully combined genetics, developmental biology and physics.


I undertook my second postdoctoral stay at the Weizmann Institute of Science, in Israel, from mid 2005 to the end of 2008. There I changed topic to get a broader picture of biophysics, and studied the connectivity in living neural networks. My research was experimental, and among other goals I developed a new technique to characterize neural connectivity using a percolation approach. The research at Weizmann gave me a major experience in cell and tissue culturing, as well as training in a variety of experimental techniques in neuroscience, from activity analysis through fluorescence imaging to multi-electrode arrays.


Since November 2008 I am a “Ramón y Cajal” research fellow at the Faculty of Physics (Department ECM) of the University of Barcelona. I am currently setting up the first biophysics lab in the Department. Research will be oriented towards neurophysics and self-organization in multicellular organisms.
