You can call me Kyle :)
I am currently a Hale Visiting Assistant Professor at School of Math in Georgia Institute of Technology (Georgia Tech). My mentor is Ernie Croot.
My Erdős number is 3.
I obtained my PhD in Mathematics from University of British Columbia (UBC) in July 2024 under the supervision of Greg Martin, Jozsef Solymosi, and Joshua Zahl. The title of my thesis is Topics in arithmetic combinatorics.
I completed my Msc in Mathematics in UBC in Jan 2021. The title of my thesis is On the clique number of Paley graphs and generalized Paley graphs.
Previously, I completed my B.Sc. in Mathematics and in Computer Science at Hong Kong University of Science and Technology (HKUST) in June 2019.
I am primarily interested in arithmetic combinatorics, analytic number theory, extremal combinatorics, finite fields, and finite geometry. I am also broadly interested in other areas in number theory and combinatorics as well their neighboring subjects, and have done research projects in algebraic graph theory, arithmetic geometry, Diophantine approximation, Diophantine equations, discrete geometry, harmonic analysis, and matrix analysis.
