Welcome to my page. I am a mathematician at the Perimeter Institute in Waterloo, Ontario. My work deals with identifying and exploiting previously unrecognized mathematical structures in various contexts. So far, I have mostly done this for mathematical aspects of quantum theory, but a diverse background in mathematics, theoretical physics and computer science enables me to do this more generally. So if unclear mathematical structures pop up in your research and you would like help in understanding them better, please get in touch!
