Leontios J. Hadjileontiadis was born in Kastoria, Greece in 1966. He received the Diploma degree in Electrical Engineering in 1989 and the Ph.D. degree in Electrical and Computer Engineering in 1997, both from the Aristotle University of Thessaloniki, Thessaloniki, Greece. Since December 1999 he joined the Department of Electrical and Computer Engineering, Aristotle University of Thessaloniki, Thessaloniki, Greece as a faculty member, where he is currently an Associate Professor, working on lung sounds, heart sounds, bowel sounds, ECG data compression, seismic data analysis and crack detection in the Signal Processing and Biomedical Technology Unit of the Telecommunications Laboratory. His research interests are in higher-order statistics, alpha-stable distributions, higher-order zero crossings, wavelets, polyspectra, fractals, neuro-fuzzy modeling for medical, mobile and digital signal processing applications. Dr. Hadjileontiadis is a member of the Technical Chamber of Greece, of the IEEE, of the Higher-Order Statistics Society, of the International Lung Sounds Association, and of the American College of Chest Physicians. He was the recipient of the second award at the Best Paper Competition of the ninth Panhellenic Medical Conference on Thorax Diseases‘97, Thessaloniki. He was also an open finalist at the Student paper Competition (Whitaker Foundation) of the IEEE EMBS‘97, Chicago, IL, a finalist at the Student Paper Competition (in memory of Dick Poortvliet) of the MEDICON‘98, Lemesos, Cyprus, and the recipient of the Young Scientist Award of the twenty-fourth International Lung Sounds Conference‘99, Marburg, Germany. In 2004, 2005 and 2007 he organized and served as a mentor to three five student teams that have ranked as third, second and seventh worldwide, respectively, at the Imagine Cup Competition (Microsoft), Sao Paulo, Brazil (2004)/Yokohama, Japan (2005)/ Seoul, Korea (2007), with projects involving technology-based solutions for people with disabilities.

Common Brain. The work is based on the construction of a "common brain" in a bilateral perception; the one that is being shared and the one that does not deviate from the norm. Starting from the point of existence (through the understanding of breathing), the multi-layering proliferation of the neurons is developed, followed by the network-activation, text-training, external-stimulation reaction and, final, emotional responsiveness. The performers participate in a formation of the sound-scape with the real-time acquisition of their encephalogram and its transform to sound material, creating an experiential perception of the "common brain" in many different aspects of its development and formation. The experiential stochasticity brings the "sound liquidness" and continuous de/construction to the foreground, making them as basic structural ingredients of the dynamically produced composition in an alternative perspective, that of the, so called, Biomusic.
