Dr. Oscar Gabriel Rodríguez Herrera
Member of the academic staff

Oscar G. Rodríguez-Herrera received a BS and an MS in Physics from UNAM, and a PhD in Experimental Physics from the National University of Ireland, Galway (NUIG), where he took a Postdoctoral Researcher position at the end of his PhD. During his time as a postdoc at NUIG, he worked in the development of a polarimetry-based technique for the analysis of specimens with features below the Rayleigh resolution limit and its applications in high resolution optical microscopy. Afterwards, he continued with his academic career as a Postdoctoral Research Associate at the College of Optical Sciences of the University of Arizona, where he worked in image processing, data analysis, electromagnetic modeling, optical coherence, and the development of novel polarimetry techniques and polarimetric data analysis strategies.

Dr. Rodríguez-Herrera specializes in Physical Optics and its applications. His main areas of interest, and expertise, are light polarization, polarimetry, optical coherence, imaging, diffraction, and their applications in material analysis, optical microscopy, the study of the properties of tightly focused electromagnetic fields, and the analysis of biological specimens. His current efforts are in the implementation of variable coherence polarimetry (an optical tomography technique with polarimetric sensitivity), the development of polarimetric optical microscopes for biomedical applications, and the development of polarimetric methods for the analysis of the structure of biological specimens.

He is coauthor of 30 research articles, 11 proceedings papers, 1 patent, and 1 patent application.
