Michael Casey (PhD MIT 1998) conducted his doctoral research at the MIT Media Lab's Music-Mind-Machine group. His research explores new approaches to computing as a creative medium and advanced computational methods for organising large multimedia collections to support digital humanties research. He is an editor of the MPEG-7 International Standard for Multimedia Content Description (ISO15938-4 Audio 2002), a standard for automatic organisation of multimedia databases. Michael is also a composer and artist and he has received a number of international awards for his works in digital media.
