The Sonification of Human EEG and other Biomedical Data


Thomas Hermann

Dr. Thomas Hermann received a Master's Degree (German Diplom) in Physics 1997 from Bielefeld University. He joined the Neuroinformatics Group of Prof. Helge Ritter at the Faculty of Technology, Bielefeld University, where he started research on sonification for exploration and process-monitoring of high-dimensional data. In 1998 he became a member of the Graduate Program Task-Oriented Communication. He received a Ph.D. with the thesis Sonification for Exploratory Data Analysis in 2002, and is currently continuing his research as research assistant with a focus on interactive multi-modal human-computer interfaces and techniques for multi-modal data exploration.

Thomas Hermann is member of the ICAD board of Directors, organiser of the first international workshop on Interactive Sonification (2004) and guest editor of IEEE Multimedia for a special issue on "Interactive Sonification" (the latter two together with Andy Hunt), German delegate of the EU COST action 287 (ConGAS, Gesture Controlled Audio Systems). He gives lectures and seminars on Neural Networks, Data Mining, Sound Synthesis, Sonification, Computer Music, and Auditory Display. He planned and developed the Bielefeld iLab (Interaction Lab) where visual, tactile and auditory displays are combined for multi-modal data exploration.
