Prof. Cecilia Noguez


Cecilia Noguez is Professor of Physics at the Universidad Nacional Autonoma de Mexico (UNAM) in Mexico City, Mexico and is recognized as one of the leading theoreticians in the area of numerical modeling of nanoscale materials and surfaces. She obtained her B.A. in Physics from UNAM in 1990, and her Ph.D. in Physics also from UNAM in 1995. She held a postdoctoral position (1995-96) in the Physics Department at Ohio University, Ohio, and joined the Physics Institute at UNAM in 1996. She also held visiting scientist positions in University of Rome II, Italy (1993-94), Ohio University (2000) and Northwestern University (2010-11). Cecilia Noguez has published more than 60 papers, receiving more than 1,500 citations in the specialized literature. Her research efforts have been devoted to develop new theoretical and computational tools to understand different phenomena observed in atomic clusters, plasmonic nanoparticles, carbon nanostructures, semiconductor surfaces, and interfaces. One important goal of these theoretical tools has been to provide reliable theoretical frameworks to compare directly with experiments. By combining first-principles density functional theory and classical electromagnetic theory, her research includes studies on the structural, electronic, and optical properties of materials, in emerging fields including plasmonics, optical activity in chiral carbon-based and metallic nanostructures, atomic adsorption processes (functionalization and selection), van der Waals and Casimir forces in nanostructures (micro and nano assembly), among others. She has been invited to give talks and lectures in different meetings and universities in Europe, USA, Australia, and Latin America. Her work has been awarded in different occasions by the Mexican Academy of Science, the Institute for Scientific Information (Thomson Reuters), and other Mexican and overseas institutions.



One of the most fascinating aspects of metal nanostructures is the optical response, which is mainly characterized by the surface plasmon resonances. We demonstrate that at the nanoscale, the number, position, width, and intensity of surface plasmons can be tailored by manipulating the size, morphology, composition, and environment of the metal nanostructures. Additionally, metal nanostructures squeeze optical fields into highly confined, nanoscale volumes, which is important for applications such as surface enhanced Raman scattering (SERS) and fluorescence, as biomedical markers and therapy, and for detection and imaging, and for improving plasmon enhanced photovoltaic devices. In this talk, I will discuss some of our key contributions to localized surface plasmon resonances of metal nanoestructures.
