He graduated in physics in 1987 from Universitat Autònoma de Barcelona. Before and during his PhD (Yale University, 1994), he worked with Prof. Juan Fernández de la Mora on aerodynamic focusing, electrospray fundamentals, 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 atomization process. After joining Universitat Rovira i Virgili (URV) as ICREA Research Professor in 2004, his research has focused on electrospray and electrospinning for the manufacturing of nanomaterials; and recently also on COVID transmission in schools. He currently leads the Droplets, intErfaces, and floWs (DEW) laboratory at URV.

I combine fluid dynamics and electricity to engineer new nanomaterials. Electrified liquid bodies eject tiny jets which can be transformed to nanoparticles (electrosprays) or nanofibers (electrospinning), or can be printed to make patterns on a substrate. Through experiment and computer modeling, we aim to (1) understand the underlying mechanisms in these processes, (2) devise strategies to create functional structures (e.g., ‘smart’ particles for nanobiomedicine), (3) characterize the properties of such structures, (4) 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 to form living tissues), and (5) develop the scale-up of these processes so they can ultimately benefit humankind. These are some of my focus areas, though my interests are broader, including respiratory drug delivery and airborne disease transmission.
