Ms. Christina Siogka holds a Master’s degree in Photonics and Nanoelectronics from the University of Crete, Department of Physics, where she specialized in laser – matter interaction and surface modification. Specifically, her research was focused on the fabrication of laser-induced periodic surface structures on bulk metallic and semiconducting materials with ultrashort laser pulses. She also received her Bachelor’s degree in Physics from the University of Crete. She is currently performing her PhD studies in Physics jointly at the National and Kapodistrian University of Athens and NCSR Demokritos. Her doctoral research focuses on the theory, design, and implementation of complex electromagnetic media, including photonic crystals, metamaterials, and metasurfaces. The project involves investigating the propagation of photonic and topological waves and developing advanced THz components such as filters, shields, lenses, and modulators. This work is conducted in close collaboration with the Institute of Nanoscience and Nanotechnology at NCSR “Demokritos,” combining theoretical modeling with experimental nanofabrication techniques.
