Her current research is oriented towards experimental media, focusing on spatial aspects of the experience of a work of art, with a special focus on the two immersive techniques: ambisonics and stereoscopy. Her recent projects are based on the idea of the separation and manipulation of spatial cues, both visual and sonic, in order to design a game of illusions, to create a continuum between the synthetic and live sources, and to challenge the borders of perceptual limitations.
