Dr. Yonny Romaguera-Barcelay holds a BSc in Physics from Universidad de Oriente, Cuba, an MSc in Physical Sciences from the University of Havana, and a PhD in Physics from the University of Porto, Portugal. His research focuses on Experimental Condensed Matter Physics, Materials Science and Engineering, with emphasis on functional and nanostructured materials, semiconductor oxides, thin films, multiferroic and magnetoelectric materials, biomaterials, electrospun nanofibers, electrochemical sensors, and environmental photocatalysis. He has experience in sol-gel processing, coprecipitation, electrodeposition, electrospinning, RF magnetron sputtering, pulsed laser deposition, and advanced structural, optical, electrical and magnetic characterization techniques. His current interests include doped ZnO and NiO nanostructures, functional thin films, sensors, photovoltaic devices, spintronics, lead-free piezoelectric materials and biomaterials for environmental and biomedical applications.
