I am not currently accepting applications from prospective PhD students. However, the Media and Arts Technology Centre for Doctoral Training is open for applications. Further funding with other colleagues within EECS at QMUL is available at the EECS website for more information.


I'm a Lecturer in the School of Electronic Engineering and Computer Science at Queen Mary University of London. I work with e-textiles and signal processing to build interactive, body-centric wearable computing systems. These systems often incorporate performance, fashion, music and/or design.

I am on the Management Team for the Media and Arts Technology Centre for Doctoral Training funded by the EPSRC and AHRC and am also a member of the Centre for Digital Music and the Centre for Intelligent Sensing.

Before returning to academia, I took on freelance engineering and consultancy projects through Anti-Alias Labs. I'm also a co-founder of Codasign, a creative technology education company that ran workshops teaching kids and adults how to use technology to develop creative projects. More information about my projects outside of QMUL can be found at theleadingzero.

I completed my PhD with the Centre for Digital Music at QMUL in 2010 under the supervision of Prof Mark Sandler. I completed my MSc in Music Technology from the University of York, UK in 2006 and BMus with double majors in Music Engineering and Computer Science from the University of Miami, Florida, USA in 2005. My full CV can be found at theleadingzero/cv.


My research interests are at the intersection of wearable computing, audio engineering, and electronic textiles. My PhD research was in spatial audio signal processing, but my more recent work has been in new textile sensors and the interface between textile and traditional circuitry. I am particularly interested in how electronics and computing can be applied to arts performance.


The PhD students currently working with me.

Angela McArthur

Angela McArthur

PhD Student (MAT, co-supervised with Prof Mark Sandler)

Angela's work explores sound and image for immersive environments in particular developing experimental approaches which emphasise sound’s impact. She synthesises technical and creative practices with auditory perception research. Whilst on the MAT programme, Angela has worked with the BBC R&D team and co-directed an experimental sound-led cinematic VR film, which aims to embody and further develop her research, and which was shortlisted for Sheffield Docfest 2017.


Sophie Skach

Sophie Skach

PhD Student (MAT, co-supervised with Prof Pat Healey)

Coming from a background in fashion design and knitting technology, Sophie's current research interests are based around smart fabrics and textile sensing systems. As part of the Cognitive Science Research Group, she looks at how textile surfaces can be used to investigate social behaviour - ranging from experimenting with fabric pressure sensors on chairs to knitted stretch sensors in jumpers.


Vanessa Pope

Vanessa Pope

PhD Student (MAT, co-supervised with Prof Elaine Chew)

Performers respond in the moment to each night's audience. However, the rehearsal period of a production establishes replicable performance dynamics, designed to give an equivalent narrative experience across audiences. How is the use of space and timing different or similar night to night? Are there patterns of spontaneity and reliability? Could these constitute the signature dynamics of a production?

Borrowing computational techniques from music performance analysis, Vanessa's research looks for patterns in the timing of speech, silence and spatial configurations across multiple recordings of the same show, which may signal reliable use of narrative devices in performance.

Rishi Shukla

Rishi Shukla

PhD Student (MAT, co-supervised with Prof Mark Sandler)

Rishi’s interest lies in the development of sound recording and listening technologies and their influence on commercial music creation and consumption practices. His current research explores possibilities for binaural virtual auditory display of music collections, with the aim of uncovering flexible and interactive means for navigating, exploring and arranging content.

An Liang

An Liang

PhD Student (MAT, co-supervised with Dr Nick Bryan-Kinns)

An is interested in the design and user experience of smart textiles interfaces for digital performance. Her current research is looking into materials for stretch sensors in order to find a solution for designing reliable textile-based sensors that can be integrated into a garment to detect a dancer's body movements.

Nida Aziz

PhD Student co-supervised with Dr Tony Stockman)

Antonella Nonnis

PhD Student (MAT, second supervisor, primary supervisor Dr Nick Bryan-Kinns)
