I am a postdoc at the Centre for the Mathematics of Quantum Theory, University of Copenhagen, hosted by Laura Mančinska. I received my Ph.D. in 2024 from the Institute for Quantum Computing and Department of Pure Mathematics at the University of Waterloo, where I was supervised by William Slofstra. Before that, I obtained my bachelor degree in Mathematics and Applied Mathematics from Zhejiang University in 2019, under the supervision of Junde Wu. I also spent a semester at Rice University as an undergraduate exchange student (2017).

Research interests

I am broadly interested in the mathematics of quantum information and computation. In the past, I have worked on approximate representation theory and its applications in quantum self-testing, delegation of quantum computation, quantum complexity, and decidability in operator algebras. You can find my PhD thesis here.
