![Headshot of Curtis](headshot211023.jpg)
I solve mathematical problems and produce computer-assisted proofs. Using techniques from satisfiability solving and computer algebra, my work has enabled the solution of many hard combinatorial problems thousands of times faster than previously possible.
Currently, I am an assistant professor in the School of Computer Science at the University of Windsor. I completed my PhD in the Cheriton School of Computer Science at the University of Waterloo, and with Vijay Ganesh I lead the MathCheck project.
See my curriculum vitae or bio for a summary of my academic career and my research statement, publication list, or showcase for an overview of my research. If you are interested in working with me, the Algorithms & Mathematics group at Windsor is accepting applications for open research positions.
As of fall 2023, I am supervising or co-supervising 12 students. My group's webpage lists the students I'm working with or have worked with in the past.

Bio
Dr. Curtis Bright is an assistant professor in the School of Computer Science at the University of Windsor. He leads the development of MathCheck, a system for verifying and finding counterexamples to mathematical conjectures. His research focuses on computer-assisted proofs, automated reasoning, symbolic computation, and discrete mathematics. He received his PhD in 2017 at the University of Waterloo for demonstrating the effectiveness of combining satisfiability checking and symbolic computation for solving mathematical problems. His work on the first computer-verifiable resolution of Lam's problem won the Jacques Calmet best paper award in 2021, and in 2022 he won an Applications of Computer Algebra Early Researcher Award. In 2023, he proved the current best known lower bound in the abc conjecture.
Detailed history
In August 2021, I co-chaired (with James Davenport) the 2021 SC-square workshop. In the fall of 2021, I taught a graduate course on computational discrete mathematics. In the winter of 2022, and again in the summer of 2022, I taught Key Concepts in Computer Science and Introduction to Algorithms and Programming II. I taught Prog II again in fall 2022, along with a graduate course in computer algebra and computational mathematics.
In July 2021, I became an adjunct research professor in the School of Mathematics and Statistics at Carleton University. In Winter 2022, an undergraduate student I supervised, Noah Rubin, defended his Bachelor's thesis; he is now a full time software developer for Canada's cryptologic agency.
I joined the faculty of the School of Computer Science at the University of Windsor in 2020 and taught Introduction to Algorithms and Programming II in the winter of 2021.
I am currently the lead developer of the MathCheck project run by professor Vijay Ganesh at the University of Waterloo. In 2020, I held an NSERC postdoctoral fellowship at Carleton University working with professors Kevin Cheung and Brett Stevens. Our major result was generating and verifying the first set of nonexistence certificates for solving Lam's problem.
Between 2017 and 2019, I was a postdoctoral fellow of the Computer Aided Research Group at the University of Waterloo. I was also affiliated with the CARGO Lab at Wilfrid Laurier University and worked with professor Ilias Kotsireas on combinatorial matrix theory. During this time, I devised the first proof that Williamson matrices exist in all orders that are powers of two.
I interned at Maplesoft in 2017 and again in 2018. While at Maplesoft I applied my research to dramatically improve some discrete optimization routines of Maple—for example, in the latest version of Maple the chromatic number of the Queen Graph of the chessboard can be computed in a few seconds instead of a few hours. I have written a number of Maple applications demonstrating how to effectively use Maple's SAT solver in a variety of problems and presented many of these applications at the 2019 Maple conference.
In March 2017, I defended my PhD thesis, supervised by Vijay Ganesh and Krzysztof Czarnecki. My thesis demonstrated the effectiveness of combining satisfiability checking and symbolic computation for solving mathematical problems.
In Fall 2015, I taught Elementary Algorithm Design and Data Abstraction alongside Gordon Cormack to 258 students. This course is the follow-up to Designing Functional Programs intended for CS and math majors and uses the programming language C.
In Summer 2015, I was the sole instructor of 145 students in Introduction to Computer Science 1, an introduction to computer science intended for non-CS majors. As the instructor I was responsible for compiling 9 assignments throughout the term and each one consisted of questions newly developed by myself.
In Fall 2014, I taught Designing Functional Programs, an introduction to computer science for CS and math majors based around the programming language Racket. I coordinated with 5 other instructors to teach 876 students.
In Summer 2014, as a part of Google's summer of code I supervised (along with William Hart) the undergraduate student Abhinav Baid and oversaw the implementation of a fast variant of the LLL algorithm for lattice basis reduction in the open source number theory library FLINT. This code is available in the latest version of FLINT in the fmpz_lll module.
In Spring 2013, I received an award for exceptional performance as an instructional assistant in the course Logic and Computation. During this term I wrote an online truth table generator for easily generating truth tables to include in assignment solutions and course notes.
In Winter 2013, I designed the SCG logo (a spoof on a proposed UW logo). At the time I was a graduate student and I've made publicly available a collection of the lecture notes that I took as a student.
In 2007, I started a personal website for nonacademic projects, though most of my effort these days goes into advancing my research program.
Awards
I won the Application of Computer Algebra Early Researcher Award at ACA 2022.
At the Maple Conference 2021 Mathematical Art and Creative Works Exhibit my submission with Bridjet Lee won the judges' choice award.
My 2020 paper A nonexistence certificate for projective planes of order ten with weight 15 codewords won the Jacques Calmet best paper award.
Bragging rights
My Erdős number is 2, through the papers Minimal elements for the prime numbers (Bright, Devillers, Shallit) and New bounds on the length of finite Pierce and Engel series (Erdős, Shallit). I have been awarded 0x$1.20 at Knuth's Bank of San Serriffe for finding a typo in The Art of Computer Programming present since the first edition (!) of volume 2 in 1969. In the 2015 version of his classic text Galois Theory, Ian Stewart cited a report of mine. Additionally, Noam Elkies once gave a talk referencing a result that I showed as an undergraduate student—the technical report is dear to my heart as one of the first papers I ever wrote.
