Prof. Javier Aizpurua

Javier Aizpurua is an Ikerbasque Research Professor at the Donostia International Physics Center (DIPC) and a distinguised researcher at the University of the Basque Country (UPV/EHU) .

Aizpurua studies the excitation of localized surface plasmons in metallic particles induced by a variety of external probes, including light. Among others he has developed theory to understand the excitation of surface plasmons in Scanning Transmission Electron Microscopy (STEM), in Scanning Tunneling Microscopy (STM), in Surface-Enhanced Raman Scattering (SERS), in Surface-Enhanced Infrared Absorption (SEIRA), or in Scattering-type Near-field Optical Microscopy (s-SNOM), among others. The understanding of the optical response of metallic nanoantennas in all these situations has been the main focus of his research during the last years.

Javier Aizpurua achieved his Ph. D. at the University of the Basque Country on the theory of Plasmon excitation by fast electron beams. After research positions at Chalmers University of Technology (Sweden) and NIST (USA), he worked at the Donostia International Physics Center DIPC as a research Fellow. He held a position as a research Professor of the Spanish Council for Scientific Research (CSIC) at the Materials Physics Center in San Sebastian until 2023, where he led the research line on the Theory of Nanophotonics, an activity that he currently continues at DIPC.
