Areas of research:
If you are interested in pursuing a MSc degree, please apply to the Perimeter Scholars International (PSI) masters program. If you are interested in working with me as a PhD student, please send me an email at [email protected] or submit an application directly to my department at the University of Waterloo and indicate that you would like to be supervised by me. Perimeter Institute is committed to diversity within its community and I welcome applications from underrepresented groups.
I am interested in the condensed matter theory of strongly correlated system, particularly quantum spin liquid, quantum criticality, conformal field theory, topological phases of matter, quantum field theory and numerical simulations. Email: [email protected]
