Dr. Julio Bastos-Arrieta graduated in Chemistry (University of Costa Rica, 2008) and held a Master’s degree in Chemical Science and Technologies (Autonomous University of Barcelona, 2010). His PhD in Chemistry (Universitat Autònoma de Barcelona, 2014) focused on the surface modification and characterization of polymeric matrices with metal nanoparticles. He worked as a postdoc fellow in Spain at the Polytechnic University of Catalonia (UPC, 2015-2017), as an Assistant Professor (University of Barcelona, 2017), and as a Postdoc Researcher at the Technische Universität Dresden (Germany, 2017-2020). In 2020, he moved back to UPC, specifically to the Molecular and Industrial Biotechnology Group, under Dr. Tzanko Tzanov, to work with nano-enabled materials to deal with bacterial resilience. In November 2021, he obtained a tenured lecturer position at the Universitat de Barcelona and enrolled in the Electroanalysis Research Group. His research expertise includes electron microscopy, material functionalization, (bio) micromotors, electrochemistry, nanomaterial synthesis, and characterization.
