Joan Rosell-Llompart graduated in physics in 1987 from Universitat Autònoma de Barcelona (Spain). Before and during his PhD (Yale University, 1994) he conducted research under Prof. J. Fernández de la Mora in aerosol mechanics and new aerosol measurement techniques. As a postdoc associate with Prof. John B. Fenn (Nobel laureate in Chemistry 2002) at Virginia Commonwealth University, he carried out research on electrospray ionization mass spectrometry. In 1996, he joined Aradigm Corporation (Silicon Valley, California, USA) to develop novel liquid micro-jet technologies for inhalation drug delivery. Since joining Universitat Rovira i Virgili (URV) in 2004, as ICREA Research Professor, his research has focused on the physics and engineering of electrospraying and electrospinning for the manufacturing of nanomaterials, including the development of these methods and their use for ultrafine 3D printing. Recently, he led a project that proposes the use of sensors to monitor and predict the airborne transmission of respiratory diseases in schools.
