Short Bio



Dr. Fotios Talantzis, obtained his BEng in Electronic and Computer Engineering in 2000. He followed this by an MSc (Telecommunications and Signal Processing) and a PhD on Acoustical Signal Processing in Imperial College London. His ongoing research has allowed for a series of journal and conference publications while in parallel he has been enriching his professional skills by working as a consultant in respectful Greek and UK companies. While studying he also lead the research for an EPSRC funded project that dealt with creation of mathematical models that investigated the robustness of 3D Audio and hands-free telephony. In April 2004 he returned to Greece to join Athens Information Technology. Since then he had extensive involvement as technical supervisor and developer in various EU and other projects. His research now concentrates on adaptive signal processing, acoustical equalization and technology for smart-spaces.
