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!

Dr. Lesa L. Beverly
Professor and Chair

Dr. Beverly holds a bachelor's in mathematics from the University of Virginia at Wise and a master's and Ph.D. in mathematics from Virginia Tech. Her areas of interest include mathematical crystallography and mathematics education.

Dr. Matthew Beauregard
Associate Professor

Dr. Beauregard was the recipient of an SFA Research and Creative Activity grant in 2017. His research investigates and develops a mechanism to explore deterministic mathematical models of aquatic ecosystems. The mathematical models are intrinsically nonlinear, which complicates the mathematical theory and presents numerous challenges to the ensuing analysis and predicative capacity. To circumvent these complications, relevant interactions and features of the ecosystem are often neglected. In this research, these complexities are not ignored and will develop new numerical procedures to accurately simulate the mathematical models. The computer simulations will provide incredible insight into the behavior and interaction between the involved species that cannot be established through current theoretical tools.

Dr. Brian Beavers
Associate Professor

Dr. Beavers' primary research areas are matroid theory and graph theory, focusing on connectivity and decompositions. He is also interested in math history, math pedagogy and recreational mathematics. Beavers holds a bachelor's in mathematics from Louisiana Tech University and a master's and Ph.D. in mathematics from Louisiana State University.
