Seminar Presentation by Dr Grace Leslie

10 Jun 2015 2.00pm to 4.00pm SUTD, Think Tank 21 (Blk 2, Level 3 Room 2.310)


Topic: An EEG and Motion-capture based Expressive Music Interface for Affective Neurofeedback
Speaker: Dr Grace Leslie, SUTD-MIT postdoctoral fellow

ABSTRACT
I will introduce the project I'm working on as a postdoc in the Audio Research Group: a musical neurofeedback system designed to invite physical, musical expression of the basic emotions, and accompanying experiments that measure participants' brain dynamics and movements using EEG and motion capture. I suggest, based on prior studies, that a classifier can be trained to distinguish the participants' expressed and felt emotion, via the EEG and motion capture data recorded with this system. I will describe my Ph.D work, for which I developed a method for studying musical engagement using simple expressive rhythmic 'conducting' gestures matching a musical pulse. I trained a classifier to distinguish EEG data of musically engaged participants from less engaged participants, thereby creating an affective brain-computer interface for monitoring musical engagement.

BIOGRAPHY
Dr Grace Leslie is committed to harnessing the expression granted by new music interfaces to better understand the link between music and emotion, with an ultimate goal of employing musical brain-computer interfaces to promote wellness. She is currently a SUTD-MIT postdoctoral fellow working with Simon Lui, Audio Research Group at SUTD and Rosalind Picard in the Affective Computing Group at the MIT Media Lab, developing a musical brain-computer interface system that is designed to invite expression and experience of emotion.

Grace completed her PhD in Music & Cognitive Science at the University of California, San Diego, where she studied the expressive movements and brain dynamics supporting music engagement at the Swartz Center for Computational Neuroscience. During the 2008-2009 year she was a researcher on the Espaces acoustiques et cognitifs team at Ircam in Paris, where she collaborated on an interactive sound installation featured in the 2009 Agora festival, and performed experiments studying the effect of active involvement on music listening. She has also worked on Audio DSP and User Experience design projects for Sennheiser and Motorola. She completed her undergraduate and Masters work in Music Technology at CCRMA, Stanford University.
