**Meet the editors**

Prof. Izabela Naydenova is a lecturer at the School of Physics and Clinical & Optometric Sciences and a principal investigator at the Centre for Industrial and Engineering Optics, Dublin Institute of Technology (DIT). She was awarded for her MSc degree in Applied Optics from the University of Sofia (1993) and her PhD degree in Physics from the Bulgarian Academy of Sciences (1999). After postdoctoral work at the Institute for Physical and Theoretical Chemistry, the Technical University of Munich, and the Centre for Industrial and Engineering Optics, DIT, she took up her current academic position in 2008. Her research interests are in holographic structures and materials for application sensing, microactuators, and security devices. She has over 120 publications in the field of holography and is the cofounder of a spinout company for holographic security devices.

Dr. Dimana Nazarova is an associate professor in the Institute of Optical Materials and Technologies "Acad. Jordan Malinovski," Bulgarian Academy of Sciences, Sofia. Currently she is the head of the Department of "Optical Metrology and Holography." She received her first MSc degree in applied optics from Sofia University and her second MSc degree in finance from the University of National and World Economy in Sofia. Dr. Nazarova received her PhD degree in physics from the Bulgarian Academy of Sciences in 2009. Her research interests are focused on holographic recording materials, optical metrology and optical plasmon polariton resonances, and more specifically in azopolymers and azopolymer nanocomposites and their applications in holographic data storage.

Tsvetanka Babeva is currently a full professor and the deputy director of the Institute of Optical Materials and Technology at the Bulgarian Academy of Sciences, Sofia, Bulgaria. She received her PhD degree in Physics from Bulgarian Academy of Sciences in 2003 and her habilitation in 2010. Her professional experience includes 18 years as a scientist in Bulgarian Academy of Sciences and 27 months as Arnold F. Graves fellow in the Centre for Industrial and Engineering Optics at Dublin Institute of Technology, Ireland. Her present research is devoted to optical characterization of thin films and developing porous materials and photonic structures for optical sensing applications.
