Krystal Guo

Dr. Krystal Guo is an Assistant Professor of Discrete Mathematics at the Korteweg-de Vries Institute for Mathematics, University of Amsterdam. Her research spans algebraic graph theory, quantum computing, and spectral graph theory, with a focus on eigenvalues of graphs and digraphs. She is also affiliated with QuSoft, the Dutch research center for quantum software.

• Education: PhD in Mathematics (2015) from Simon Fraser University under Bojan Mohar.
• Prior Positions: Postdoctoral stints at Université de Montréal (2019-2020), Université Libre de Bruxelles (2017-2019), and University of Waterloo (2015-2017).

Her research bridges linear algebra and combinatorics, with applications to quantum information theory, directed graphs, and linear optimization. She actively explores connections between graph polynomials, association schemes, and quantum walks.

Recent publications span graph isomorphism complexity, quantum error correction, and four-color theorem proofs using generating functions. She serves as Managing Editor of the Electronic Journal of Combinatorics since 2022 and organizes the General Mathematics Colloquium at UvA with Eni Musta and Jeroen Zuiddam.

Key Scientific Awards: 2013 finalist in Simon Fraser University’s 3MT thesis competition.

She maintains an active research blog, Graphs on Napkins, and contributes to open-source mathematics via GitHub repositories containing cubic graph census data and computational tools.
