**Meet the editor**

Dr. V. N. Stavrou is currently an adjunct member at the Hellenic Naval Academy, Piraeus, Greece. He received his MSc and PhD degrees in Theoretical Solid-State Physics from the University of Essex in England, in 1995 and in 1999, respectively. He has held postdoctoral positions at the following research institutions: (a) Deutsche Forschungsanstalt fur Luft und Raumfahrt e.V (German Aerospace Research Center) in Germany; (b) Helsinki University of Technology; (c) State University of New York (SUNY) at Buffalo, USA; and (d) University of Iowa, USA. He is specifically interested in searching the electronic, optical, and lattice properties of semiconducting low-dimensional structures (quantum dots and quantum wells, among others). These properties are of special importance for the quantum computing architecture and laser technology. He has published his research work in reputable journals related, among others, to quantum computing, spintronics, decoherence in quantum dots, diluted magnetic semiconductors, and phonon models in low-dimensional structures.
