    Biography

    Mr. Lysaght received his B.A. degree in Music and Mathematical Physics in 1984, his H.Dip.Ed. in 1991 and his M.Comp.Sci. from NUI, Maynooth in 1996. He is currently Deputy Head of the Department of Computer Science and is a permanent member of the lecturing staff. Mr. Lysaght's main Ph.D research area is sound analysis and synthesis, particularly the area of timbre morphing with applications in the area of synthesis and composition. He uses the Modal Distribution as a time-frequency representation for timbre and develops signal processing techniques for morphing. This research is carried out in collaboration with Dr. Victor Lazzarini of the Music Department and Dr. Joseph Timoney of the Computer Science Department at Maynooth University. This group of researchers regularly publish papers in the area of signal processing techniques for audio applications.
