Mathematical Sciences


As one of the oldest and most fundamental sciences...

Mathematics is still the basis for understanding and solving the planet’s economic, scientific, engineering, physics, and business problems.  It is also one of the most dynamic fields in which to work.  Mathematicians use computational techniques, algorithms, and the latest technology to meet the ever-increasing demand for data analysis and statistical information.  At NIU, you’ll not only learn the fundamentals, but will also choose electives that prepare you for graduate or professional school or one of dozens of exciting careers in this challenging and vital field. 

Where it all adds up

Distinguished Faculty

Reflecting the dual teaching/research role of a major university, our professors are not only nationally recognized researchers, but award-winning teachers, as well. Most mathematics majors will never have a math class with more than 25 students, and they will be taught by regular faculty, not graduate assistants.

Ready for a Real Challenge?

In addition to NIU’s Honors Program, we have our own Honors program, which recognizes students who excel in their studies. We also offer master’s and doctoral degrees, programs for which our graduates are very well prepared, whether they pursue these degrees with us or at another institution. 

Not Just About the Numbers

There are plenty of opportunities to learn beyond the classroom, too. You might work with faculty on research projects or complete an internship with a leading corporation. You could compete in local and national mathematics competitions or join our Math Club for stimulating discussions, tours of local labs, movie nights and socializing with other majors. Or, come to one of our Friday afternoon seminars to hear distinguished professors and graduate students present on a variety of topics. 

Doing the Math

Recognizing that mathematics is one of the most challenging subjects, we offer one-on-one and group tutoring in our Mathematics Tutoring Center. Topic sessions are offered throughout the week, summarizing main points and answering questions posed in the previous week’s material. Exam review sessions and practice exams are also offered.
