The RASA Project  is a multimedia performance at National Sawdust (NYC) responding to the climate crisis, originating from Columbia University and developed with a transdisciplinary team of musicians, neuroengineers, choreographers, and visual artists across Columbia, Manhattan School of Music, Yale, and Tsinghua. The work investigates how real-time biosignals and acoustic data can be reframed as expressive material for live audiovisual practice. A dancer wearing a brain-sensing headband becomes the spirit of the Earth, her neural activity and the live music co-shaping evolving ink-painting visuals across seven chapters. As lead visual designer in TouchDesigner, I researched how different EEG wavebands correlate with emotional states, prototyped multiple mappings between data and image, and developed a layered visual system where acoustic frequency bands drive responsive brush behavior on the foreground while amplified EEG alpha waves animate a 3D particle field of decaying letters in the background. The project asks how computational tools can give embodied, affective phenomena like neural activity and climate grief a legible visual form on stage.
