Daniel Sánchez-Portal is the Head of the Modelisation and Simulation group in the Materials Physics Center CSIC-UPV/EHU in San Sebastián. In 2005 he became a Tenured Researcher at CFM CSIC-UPV/EHU and a Research Professor in 2018. He was elected Fellow of the American Physical Society for his contribution to the development of methodologies for electronic structure calculations in 2016. His expertise and research interest cover the methodology of DFT based first-principles electronic structure calculations and its application to the study of nanostructures and surfaces. He is currently focused on the study of the electronic properties of covalent molecular networks, graphene nanostructures and other low-dimensional structures on surfaces in collaboration with several experimental groups, as well as to the application of TDDFT and other first-principles techniques to problems in nanoplasmonics and ultrafast electron dynamics at surfaces. He has published over 160 scientific papers with a significant impact.
