Stephen Choi

Stephen Choi is a Professor in the Department of Mathematics at Simon Fraser University (SFU), part of the Faculty of Science. He holds a Ph.D. in Mathematics from the University of Texas at Austin (1996), an M.Phil. and B.Sc. from the University of Hong Kong (1991 and 1988, respectively). His research focuses on Number Theory, particularly Diophantine equations, Goldbach-Waring problems, and polynomials with restricted coefficients. He explores topics like Littlewood polynomials, L4 norms, and merit factors of binary sequences, often applying analytic methods such as the Hardy-Littlewood circle method.

• Teaching: Courses include MATH 260 (Differential Equations) and MATH 342 (Elementary Number Theory).

Research Interests

Choi’s work bridges classical number theory and modern analytical techniques. He investigates prime solutions to Diophantine equations (e.g., Goldbach-Waring problems) and properties of polynomials with restricted coefficients (e.g., Littlewood polynomials’ L4 norms). His recent studies include autocorrelation coefficients of Rudin-Shapiro polynomials and divisibility principles in integer sequences.

Grants & Awards

No specific awards are listed, but his extensive publication record reflects sustained recognition in number theory.
