Develop a Sought-After Quantitative Skill Set

Oberlin's Mathematics program nourishes curious minds interested in applying creative and collaborative problem solving to a world of ideas, puzzles, and proofs. We also develop a quantitative toolbox and critical frame of mind, preparing students for careers in a range of fields, from economics and computer science to data analytics and statistical modeling. Many of our graduates pursue advanced degrees in mathematics and related fields, even becoming professors themselves. Still others immediately find jobs in quantitative fields. For example, recent graduates have become economic analysts at the Federal Reserve Bank, software engineers at Google, and high school math teachers.

A Collaborative Learning Community

Mathematics is a collaborative field. Most papers are co-authored and discoveries made in teams. Cooperating on problem sets is standard, and we even have some group office hours to help you meet new students to collaborate with. We also support a feeling of community by getting students and faculty together informally, for weekly teas, monthly pizza lunches (with a fun talk at the end!), and yearly Pi Day celebrations. Each year, several fourth-years will collaborate one-on-one with a faculty member for an Honors Project.

Over 60% of math majors also have a second major, many in a related quantitative field

Featured Courses

FYSP 028


Explore the science of making and breaking secret codes. We start with codes that Julius Caesar would have used in his armies. To make more sophisticated codes, we need to learn about a branch of mathematics called number theory. These tools will help us understand the modern cryptosystems (like RSA) that the internet is built on.

Taught by
Benjamin Linowitz
MATH 220

Discrete Mathematics

Mathematics is a language, and this class teaches you to “speak math.” We introduce topics you will not have seen in calculus (such as logic, sets, induction, number theory, combinatorics, graph theory) and emphasize creative problem solving and proof writing. At the end, you will be prepared to tackle many of our upper level offerings.

Taught by
Jack Calcut
MATH 335


Dealing with uncertainty is critical in many applications of mathematics. For example, it is important in machine learning, statistical modeling, economics, actuarial science, and physics. This class uses the tools you’ve learned in 200 level classes to give uncertainty and probability a firm mathematical foundation, ready to be applied to other fields.

Elizabeth Wilmer
MATH 357

Harmonic Analysis

Ever since the imperfections of Pythagorean tuning gave evidence for the existence of irrational numbers, music has inspired important developments in mathematics. We start with these classical results and work our way towards modern methods like the Fourier transform, with its applications to acoustics.

Student Profiles

The Course that Changed Everything

Alina Zhu always loved how math could be used to untangle musical principles. It could further a career. It was, she thought, a useful tool. But in the fall of her sophomore year, she took a math course that changed her entire perspective on the field.

Particle Systems as Epidemics

Mathematics major Garrett Robins has been researching the behavior of particle systems to model the diffusion of disease and opinion.

The Future of Sustainable Buildings

Math and physics double major Grant Sheely was also captain of Oberlin’s cross country and track and field teams. He went on to work as a sustainability coordinator in New York City.
