Short CV and Full CV

About

I studied Physics at Harvard University (BA, ’92), then spent two years at the Institut de Recherche et Coordination Acoustique Musicale (IRCAM) under a fellowship awarded by Harvard and the Ecole Normale Superieure. I then completed the MSc and PhD degrees in Electrical Engineering at Stanford University (’96 and ’01, respectively), while working at the Center for Computer Research in Music and Acoustics (CCRMA). I was subsequently a postdoctoral researcher at the Stanford Space Telecommunications and Radioscience Laboratory, and a Lecturer at the Sonic Arts Research Centre at the Queen’s University Belfast.

I currently work on computational acoustics, for applications in sound synthesis and virtual acoustics. Special topics of interest include: Finite difference time domain methods, distributed nonlinear systems such as strings and plates, architectural acoustics, spatial audio in simulation, multichannel sound synthesis, and hardware and software realizations.

A sideline is joint work with composers of electroacoustic music. Other interests include virtual analog effect modelling and artificial reverberation design, modelling of electromechanical instruments, shock wave propagation in tubes, numerical absorbing boundaries in acoustics applications, and large-scale audio rendering using graphics processing units (GPUs) in conjunction with the Edinburgh Parallel Computing Centre.

Many of the research directions described above formed part of an ERC-funded project, NESS, running jointly with the Edinburgh Parallel Computing Centre over the period 2012-2017. See the project website for more information:
