# Department of Mathematics

The department offers Bachelor of Science degrees in Mathematics and in Applied Mathematics with an optional concentration in Financial Mathematics. These programs provide a core of basic mathematics courses along with flexible choices of electives, which permit both a well-rounded education and preparation for math-related careers. Students may focus their studies in financial mathematics, mathematical biology, mathematical physics, mathematical statistics, or computational mathematics. Employment objectives can be focused on quantitative careers in business or government, teaching at the secondary level, or graduate study in mathematics and/or related areas.

Specific curriculum requirements are available on the Registration and Records website.

## Academic Enrichments

Many undergraduates in the Mathematics Department participate in research programs with members of our faculty presenting their results in both regional and national meetings. The research projects come from many areas of pure and applied mathematics including chaos theory, the path-space of various surfaces, numerical methods for solid mechanics, and math modeling in the life-sciences, such as orthopedic soft tissues and blood flow in the brain. Other enrichment activities include special topics courses, such as The Mathematics of Ranking and Clustering, and programs away from campus, such as the NSF sponsored Research Experience for Undergraduates, the Budapest Semester in Mathematics, and the Society for Undergraduate Mathematics, a Student Chapter of the Mathematical Association of America, opened to all students interested in Mathematics.

Talented students are encouraged to consider a 5-year Accelerated Bachelors/Masters Program (ABM). A key feature of the program is counting up to 12 hours of graduate courses to both the BS and MS degrees. Students can choose between the MS in Mathematics, Applied Mathematics, or Financial Mathematics.

### Honors Program

Students who demonstrate high aptitude in mathematics are invited to participate in the Mathematics Honors Program. The program provides intensive mentoring and preparation for graduate studies. Students are invited to join the program if they are recommended by a teacher in an upper-level math course and have a math GPA of 3.5 or higher. To complete the program, students must take MA 426 Mathematical Analysis II, at least three graduate level math courses, and do a research project. Math Honors students often study abroad at programs such as the Budapest Semesters in Mathematics or Math in Moscow and participate in funded summer research at other universities.
