Dr Sakellaris Mailis recently joined the Centre for Photonics and Quantum Materials, Skolkovo Institute for Science and Technology (Skoltech) as an Assistant Professor. Before joining Skoltech he was a Principal Research Fellow at the Optoelectronics Research Centre (ORC) at the University of Southampton, UK. He graduated from the Physics department of the University of Crete in Greece where he completed his PhD on the subject of “Optical signal processing with Photorefractive materials” Dr Mailis has been involved in research that is related to holographic data storage and processing as well as laser-processing of ferroelectrics and other photonic and electronic materials. At the ORC he led the “lithium niobate” group and over the years he made contributions in the area of laser materials processing, direct laser-writing of optical waveguides and ferroelectric domain engineering in optical ferroelectric crystals as well as laser-writing of refractive and diffractive structures in semiconductor materials. At Skoltech he is exploring methods for laser-induced inscription of photonic circuits in semiconductors, the localized synthesis of 2D materials, and the exploitation of ferroelectric/semiconductors hybrids for photonic applications. His research activities are reflected in numerous articles that have been published in scientific journals and conference contributions including review articles and book chapters.
