Areas of research:
If you are interested in pursuing a MSc degree, please apply to the Perimeter Scholars International (PSI) masters program. Perimeter Institute is committed to diversity within its community and I welcome applications from underrepresented groups.
My research focuses on mathematical aspects of quantum information and computation. I use information theory, number theory and geometry to study optimal and explicit codes and protocols for computing and for manipulating quantum information. Specific research interests include quantum Shannon theory, topological quantum computing, quantum field theory and the arithmetic of quantum circuits.
