Background and Research Interests
I have been a member of TIM/ISSCO since February 2007, where I am employed as a research associate. My research interests concentrate on the development and evaluation of multilingual multimodal dialogue systems on mobile devices. I am involved in the MedSLT and CALLSLT projects, and I have previously contributed to the Regulus and the IM2 projects. All of these projects are/were funded by the Swiss National Science Foundation.
At the moment, I am lead developer in the project "Web-Based Deployment of Speech-Enabled Applications for Medicine and Education", funded by the Ernest Boninchi Foundation.
I hold a BSc (5 years degree) in Computer Engineering, an MSc in Computer Engineering and an MSc in Engineering Management from TU Crete and a PhD in Multilingual Information Processing from the University of Geneva. Before joining TIM/ISSCO I worked as a software engineer developing telephone-based speech recognition applications. I also worked as a researcher on relevant technologies including automatic speech recognition and dictation systems, voice user interfaces and multimodal interaction at TSI. I also serve as an expert reviewer for the European Commission.
I am certified as a "Java 7 Professional Programmer" by Oracle, as a "C++ Associate Programmer" by the C++ Institute and as a "Professional Scrum Master I" by Scrum.org. Between February and May 2012 I attended the "venture challenge" start-up training program offered by the Commission for Technology and Innovation CTI (14 modules - 45 hours). I have also completed the "Advanced Voice User Interface Design" course offered by the Nuance Speech University.
