About

A passion for teaching and research

SFA’s mathematics and statistics professors are a diverse group with a variety of backgrounds and research interests. But they all have one thing in common: They love teaching. As a mathematics and statistics student, you’ll work with instructors and professors who specialize in everything from mathematics education and differential equations to applied probability and mathematical economics. You’ll also work with several faculty members who started their educational journeys right here at SFA – Axe ’em, Jacks!
