About Me
I am a first-year PhD student at Stanford University's Center for
Computer Research in Music and Acoustics (CCRMA.) I completed an
MA in Music, Science and Technology at CCRMA in 2007. My previous work experience in audio technology and DSP is detailed in my resume and curriculum vitae.
Research Interests
- I am interested in the relationship between
between music and movement, and am currently conducting research in
movement and gesture sonification.
- I enjoy creating new musical instrument interfaces and am
interested in human-computer interaction as it relates to music
performance.
- I continue to study digital audio signal processing. At the moment I'm interested in investigating rhythm tracking algorithms.
Projects
2007 - 2008
- For the fall quarter SoundWire Ensemble I performed on a
"hyper-melodica", which is an acoustic melodica processed in Max/MSP
and controlled with pads and sliders on a Tigger Finger. The
musical merits of this instrument are open to debate.
- I am working on two movement sonification projects as part of the class the Anatomy of Movement.
Using a 3D motion capture system we can measure and sonify human
movements. One project is to find out whether real-time
sonification can help improve the upper limb movements of children with
cerebral palsy. The other project is to sonify recordings of
different dance movements and see if people can match the sound to the
movement that generated it.
2006 - 2007
- The WaveSaw was an
instrument that Nate Whetsell, John van Stoecker, and myself created
for Music 250 (Physical Interaction Design for Music.) It uses
flex sensors to measure the curvature at a number of points on a
flexible metal "blade." These measurements are used to recreate
the shape of the blade in the computer, and this shape can be used as a
wavetable for scanned synthesis or as a spectral shape to be applied to
another signal. Here is the 180Mb video of the original demonstration of the WaveSaw.
- CyberBeat
was my final project for Music 220a and CS377 (Cybernetics and Design.)
It consists of an interactive game implemented in Pd in which a
player tries to create a rhythm that matches a goal syncopation.
As they approach the goal state the audio becomes progressively
less distorted. I also documented a cybernetic model of
music-making which was used to design the game.
Publications
- A paper on the WaveSaw that Nate Whetsell and I presented at NIME 2007.
- A paper on some reverb work I did while working at Creative Labs and presented at DAFX 2000.
Music
I create electronic pop music which I occasionally perform. Some examples of this can be heard on myspace music.
I occasionally compose electro-acoustic music, and hope to do more of this soon.
I play piano a bit, and have enjoyed singing choral music.
