He graduated in physics in 1987 from Universitat Autònoma de Barcelona. Until his PhD (Yale University, 1994), he worked with Prof. J. Fernández de la Mora on aerodynamic focusing, inertial impaction, electrospray atomization, and differential mobility analysis. As postdoc associate with Prof. John B. Fenn at Virginia Commonwealth University, he did research on electrospray ionization mass spectrometry. In 1996 he joined Aradigm Corporation (California, USA) to develop liquid micro-jet technology for inhalation drug delivery. There, he co-discovered, with Prof. A. Gañán-Calvo (Universidad de Sevilla, Spain), the "flow blurring" fine liquid atomization regime. Since joining ICREA and Universitat Rovira i Virgili (URV) in 2004, his research has focused on electrospray and electrospinning for the manufacturing of nanomaterials. He leads the Droplets, intErfaces, and floWs (DEW) research lab at URV.
Under the action of electrostatic fields, liquid interfaces form liquid jets which are thinner than one hundreth of a human hair. We use such fine electro-hydrodynamic jets as templates for manufacturing of nanofibers, nanodroplets, and nanoparticles. Such elements (fibers, droplets, and particles) find use in many fields, like heterogeneous catalysis, non-linear optics, pharmaceutics, chemical sensing, solar energy harvesting, and others. We devise strategies for engineering the internal structure of such elements, as well as for their assembly as micro/nano- "building blocks" into suprastructures. We also focus on the function-structure relationships of the synthesized materials, and the modelling of the physical and physicochemical processes underlying their production. We are also investigating the scaling up into arrays of electro-hydrodynamic emitters for materials production.
