Principal Researcher at the Institute of Language & Speech Processing. Holder of Physics degree from Patras University, MSc in Engineering and in Cognitive Science and PhD in Cognitive Science from Brown University (USA). He has worked in Greece and the U.S.A. on speech perception, auditory processing, reading, spelling, signal processing algorithms, and computer based training of language skills . His activities include project management, software design and implementation, design and conduct psychoacoustic and psychometric experiments, as well as study, optimization and assessment of algorithms and training methods. Co-ordinator of European projects CIMWOS (automatic archival of multimedia material) and OLP (computer-based speech therapy support). Principal investigator for eMaDys, VLEMA and LAMDA, to develop software for automated screening of students with possible learning disabilities. He teaches cognitive science, memory and learning, and cognitive modeling at the graduate program on “Basic and Applied Cognitive Science” of Athens University, as well as acoustic and articulatory phonetics at the graduate program “Special Education – Speech Therapy – Counseling” of Athens University.
