I was taught that my career is about more than my success. I must help others as well. You must lift as you climb.
Dr. Gloria F. Gilmer

Biography

Professor Gibbons wants to change the world. From stumping for Dukakis-Bentsen ‘88 as a first-grader and mailing her first one-pager to the White House when President George H.W. Bush came out as anti-broccoli in the early ’90s, she has never been afraid to speak up on something that matters to her. Though her early efforts to affect political (and vegetable) change were not successful, she’s gotten better with practice.

Courtney Gibbons is a mathematician and policy worker with experience in the legislative and executive branches of the Federal government. Currently an associate professor of mathematics, she joined the faculty at Hamilton College in July, 2013.

In the 2023-2024 academic year, Dr. Gibbons is a fellow hosted at the National Science Foundation in the Computer and Information Sciences and Engineering Directorate, Intelligent Systems Division, as an AI policy fellow through the AAAS Science and Technology Policy Fellow program. In the 2022-2023 academic year, she was a legislative branch fellow working for the majority staff of the Homeland Security and Governmental Affairs Committee of the U.S. Senate (Chairman Gary C. Peters) covering parts of the portfolio related to Federal data, artificial intelligence, and financial assistance.

In her life as a mathematician, Professor Gibbons studies commutative and homological algebra, and her primary research interest is the study of infinite free resolutions (often through the lens of Boij-Soderberg theory). Gibbons also has a secondary interest in algebraic statistics. Since coming to Hamilton College, Professor Gibbons has supervised several commutative algebra undergraduate research projects at Hamilton, the Willamette Valley Mathematics Consortium REU, and the COURAGE (virtual) REU. She is currently an elected member of the Executive Committee of the Association for Women in Mathematics.

Daughter of a jazz musician and public school teacher, Professor Gibbons grew up near New Haven, CT; she attended public schools in West Haven, Woodbridge, and Bethany, CT and earned her diploma from Amity High School in 2000. In 2006, she graduated Summa Cum Laude with her B.A. in mathematics with disctinction from the Colorado College in Colorado Springs, CO. Subsequently, she worked for CC’s Math and Computer Science Department for a year after graduation as a paraprofessional. In 2009 and 2013 respectively, she earned her M.S. and Ph.D. in mathematics from the University of Nebraska-Lincoln.

In addition to being a multiply-certified math nerd and a reformed college dropout, Professor Gibbons likes to rock climb, argue about notation, and snuggle with cats.

Courses

Math 325 (Writing Intensive): Modern Algebra

The word Algebra and its mathematical connotation stem from a 9th century Arabic treatise by al-Kwarizmi. This historical text dealt with finding the roots of a general quadratic polynomial equation, $ax^2+bx+c = 0$ for nonzero $a$, by completing the square, and this is where our journey begins. By the end of the course, we’ll have an understanding of what tools and techniques modern (19th and 20th century) algebra brings to bear on polynomials and their roots.

Math 512: Number Theory

Number Theory is the study of the properties of the positive integers. Topics include divisibility, congruences, quadratic reciprocity, numerical functions, Diophantine equations, continued fractions, distribution of primes. Applications will include cryptography - the practice of encrypting and decrypting message, and cryptanalysis - the practice of developing secure encryption and decryption protocols and probing them for possible flaws. Students will also explore topics of interest independently.

Math 498 (Seminar): Mathematics in Social Context

This course is designed to examine issues of social, structural, and institutional hierarchies that intersect with mathematics and statistics. This year, the course will examine the themes of Belonging, Civil Rights, Political Districting, and Algorithms.

A Hypergraph Characterization of Nearly Complete Intersections

Recently, nearly complete intersection ideals were defined by Boocher and Seiner to establish lower bounds on Betti numbers for monomial ideals (arXiv:1706.09866). Stone and Miller then characterized nearly complete intersections using the theory of edge ideals …

The Math of Online Privacy

Whether you’re buying shoes from Zappos or voting on a networked ballot box, you want to be confident that your information is verified (it really came from you!) and secure (only you and the approved second parties can see it!). Professor Gibbons will talk about the math behind …

The Real Friends are the Betti Numbers We Calculated Along the Way

Ever wondered what your life might have been like if you chose differently in the past? This talk is about how I nearly became a geometric group theorist – until I saw homological algebra used to prove theorems about modules. My emphasis will be on what Betti numbers are, a …

On this episode of My Favorite Theorem, we were delighted to talk with Courtney Gibbons, a mathematician at Hamilton College, about Emmy Noether’s isomorphism theorems. Listen to Episode 73!

So You Think You're Bad at Math (video pep talk)

I’ve had a lot of conversations with students lately that start with disclaimers like, I’m sorry, I’m not really good at math, so…, and since it’s not so easy to give a pep talk in-person with the whole pandemic and everything, I thought I’d give the pep talk here. Watch the Pep Talk!
