Terms and Conditions
Terms and Conditions is a composition for voice and live electronic processing with accompanying visuals. While a vocalist reads Google’s “Terms of Services”, a keyboardist employs granulation techniques, filtering, LPC, and channel-vocoder effects to highlight, humorize, or obfuscate the text. In dramatizing the text in various ways, the piece draws attention to the contradiction between its light and conversational tone and the underlying message as it relates to digital ownership and privacy.

Creepy Robot
My work in electronic music and instrument building often involves aspects of writing – or hacking apart – computer code, and programming small embedded microprocessors. This kinetic sculpture is the result of experiments in controlling robotic movement and deep learning algorithms in computer vision.
The piece uses a camera coupled to a computer vision algorithm that identifies the most conspicuous, attention grabbing element in the visual field (Itti et al., IEEE PAMI, 1998). Camera input is converted into five parallel streams according to color, intensity, motion, orientation, and flicker, which are visible at the bottom left of the screen. These streams are then weighted and fed into a neural network to generate a saliency map, visible at the right-side of the screen. The robot arm is then programmed to move towards the most salient object, identified by the green ring on the screen on the left
This simple coupling – computer vision and movement – generates eerily life-like behaviors that are often delightfully unpredictable.
below is some documentation of early prototypes

Yale Laptop Ensemble
We had a fantastic – and big! – group of students in this year’s Laptop Ensemble. You can visit the class website here for more information, and watch a few videos of rehearsals and the final presentations below.

Musical Acoustics and Instrument Design
Dr. Larry Wilen and I co-teach a course in musical acoustics and instrument design in Yale’s Center for Engineering Innovation and Design. Here’s a brief video from a story WNPR produced on the class.

Sprout Instrument
I have been working with a team of undergraduate students to design an interface for music production and sound synthesis using the HP’s immersive computing platform called the Sprout. We have been using the depth camera to identify and segment physical objects in the workspace, and then use the downward-facing projector to map animations onto the surface of the objects. This project is part of the applied research grant, Blended Reality, with is co-funded by HP and Yale ITS.
