He graduated in physics in 1987 from Universitat Autònoma de Barcelona. Before and during his PhD (Yale University, 1994), he worked with Prof. J. Fernández de la Mora on aerodynamic focusing, 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 (University of Sevilla, Spain) the Flow Blurring liquid atomizer. Since joining Universitat Rovira i Virgili (URV) in 2004 as ICREA Research Professor, his research has focused on electrospray and electrospinning for the manufacturing of nanomaterials, and other aerosol science related topics. He currently leads the Droplets, intErfaces, and floWs (DEW) lab at URV.

Broadly, I am interested in using fluid motion (fluidics) to design nanomaterials. More specifically, by using electricity, liquids can be made to eject tiny jets, and such jets can be transformed into particles (electrosprays), nanofibers (electrospinning), and other structures. By both experiment and computer modeling we aim to (1) understand underlying physical mechanisms in these fluidic processes, (2) devise nano-fluidic strategies to create functional structures (e.g., ‘smart’ particles for nanobiomedicine), (3) engineer ways to assemble them into larger, functional supra-structures (e.g., high-resolution 3D printing for assembling nanofibers into scaffolds where cells can grow and form living tissues), and (4) develop the scaling up of these fluidic processes, so they can ultimately benefit humankind. These are some of my focus areas, although my interests are broader, including inhalation medicine and respiratory disease transmission.
