Associate Professor, Key Laboratory of Mathematics Mechanization, Chinese Academy of Sciences. (Prior to this, I was a research associate at the School of Mathematics, University of Bristol working with Ashley Montanaro and Noah Linden. I received my PhD at the University of Chinese Academy of Sciences.)
Research interests: quantum computation, quantum algorithms, quantum complexity theory and some relevant mathematics
My research aims to better understand the power of quantum computers. I am especially interested in quantum algorithms, quantum query, communication and circuit complexity. I am also interested in symbolic computation, where I use tools from Clifford algebra, computational algebraic geometry, and invariant theory to automated reasoning. Some other interesting research topics include the Kaczmarz method, and randomised numerical linear algebra.
