Andre Holzapfel is currently post-doctoral researcher in the Compmusic project. His work is conducted in co-operation between MTG in Barcelona and Bahçeşehir University in Istanbul, and the focus of his research is exploring rhythmic and tonal properties of Turkish Makam music.
Before he was with INESC Porto for a one-year post-doc project on "Music Synthesis by Analysis". From September 2010 until February 2011 he was invited for a mini post-doc OFAI in Vienna, working on improvement of rhythm descriptors.
On 2 March 2010, he successfully defended his Ph.D. thesis which has been conducted in the Multimedia Informatics Lab at University of Crete. Between October 2009 and June 2010 he was a lecturer at the Department of Music Technology & Acoustics
at the Technological Educational Institute of Crete.
His research interest is Music Information Retrieval. The subject of his
thesis was the development of methods for analysis and information retrieval of traditional forms of music. The goal was to detect automatically
morphological similarities between different pieces. The thesis was supervised
by Yannis Stylianou. His work was
funded by the Institute of Computer Science.
He graduated in 2004 at the Department of Media at University of Applied Sciences in Duesseldorf Germany. He received his master degree at the Department
of Computer Science at University of Crete in 2006.
Before attending the postgraduate programme in Crete, he was working as a software developer at Creamware Datentechnik. There he was in charge of the development of electronic tube and electric circuit emulations, which are now used in the Dynatube
guitar and bass amplifier plugins.
