Jeffrey Barton (Professor of Mathematics) Number theory, approximation theory.

Jeffrey Barton

I am originally from Baton Rouge, Louisiana, and I grew up there and in Houston, Texas. After graduating high school in Houston I returned to Baton Rouge to attend Louisiana State University. At LSU I completed a double major in mathematics and English with an emphasis in creative writing. Early in my undergraduate experience I knew that I wanted to be a college professor, and in the end I decided to pursue an academic career in mathematics. I graduated from LSU in 1992 and entered graduate school that same year at the University of Texas at Austin. In 1999 I completed my Ph.D. in mathematics and accepted a position here at Birmingham-Southern College. My mathematical interests include probability, statistics, and mathematical modeling, particularly models for the spread of infectious diseases. I love teaching all levels of mathematics, and I particularly enjoy doing so as a member of such a dedicated and supportive department.

Caleb Moxley (Assistant Professor of Mathematics) Topological dynamics and ergodic theory, information theory, and data science

Caleb MoxleyAs an Alabamian who was intellectually reared in Virginia, I am committed to liberal education in the South, which is why I'm proud to be a part of the Mathematics Department at 'Southern. My roots run from Montevallo and Chilton County, Alabama – where I was born and raised on a dirt road off a dirt road – to the University of Alabama at Birmingham – where I completed my graduate studies. My time between was spent at Randolph College in Lynchburg, Virginia, and at the University of Reading in Reading, England. Before arriving at BSC in my current role, I taught at the Brock School of Business at Samford University, Randolph College, UAB, and BSC. My mathematical interests include topological dynamics and ergodic theory, information theory, and data science, and I am an eager educator of students at every stage of their mathematical development.

In my free time, I sing with St. Mary's-on-the-Highlands and Steel City Men's Chorus, work with queer health and LGBTQ+ advocacy organizations, and can be found running through Birmingham trails and neighborhoods.

Bernadette Mullins (Professor of Mathematics) Abstract algebra.

Bernadette Mullins Although my mother was English and my father was Irish, I grew up in Canada and the Midwest. I dabbled in biology at Western Illinois University until I took calculus and got hooked on mathematics. I headed on to the University of Iowa for graduate school where I fell for commutative ring theory. I spent a few years on the faculty at Youngstown State University in Ohio before finding my academic home here at Birmingham-Southern College. I love teaching and thinking about mathematics (especially extensions of commutative rings and questions about factorization) and mathematics education. Other favorites include music, traveling, dark beer, cycling, hiking, movies and eating food that other people cook. E-mail:

Douglas Riley (Associate Professor of Mathematics )Functional analysis, numerical analysis.Douglas Riley

I was born in South Dakota, moved to North Dakota as an infant (where, according to my father, "The wind blows so hard it makes your hair hurt") and have spent the rest of my life trying to move south. The first stop on my trip south was Greencastle, Indiana where I grew up and also attended college at DePauw University. At DePauw, I double majored in Mathematics and Computer Science, worked as a tutor in DePauw's version of the Quantitative Reasoning Center, and spent too much time goofing off. I also happened to meet Sheryl Teeguarden (yes…her last name was spelled that way)

After college I spent two years working for Allison Transmission Division of General Motors as a Systems Analyst for the Marketing Department (I still don't know what the title meant). I also started to date Sheryl at this time and life was good. Yet I missed academia, and mathematics in particular, so I decided to go back to school and give up the hefty (at that time) salary that I was earning at GM. I quit my job, got married, bought my first home, started graduate school, and moved to Lexington, Kentucky, all in August of 1993. I loved my time at UK and spent a total of six years in Lexington getting my PhD in Mathematics. (I probably could have finished my degree earlier, but I learned how to play Bridge and it's much more tempting to play Bridge than to do mathematical research, although mathematical research is also fun.)

I continued my trek south with the move to Birmingham and started at Birmingham-Southern College in the fall of 1999. Since that time I have had three children, Amanda, Eliza and Ivan, with have no plans for any more. I continue to play Bridge, although it is more difficult to find the time with three children, and life is good. I enjoying teaching and am blessed with wonderful colleagues. I have adapted well to living in the south, and enjoy the weather (no more snow for me!). Although I still don't really understand the importance placed on college football, and have refrained from becoming a fan of either Alabama or Auburn, I can accept this oddity. Birmingham and BSC are both lovely places to live and work and I feel blessed to be able to call them both Home. Email:

Sebastian Troncoso (Visiting Instructor of Mathematics) Arithmetic dynamics and arithmetic geometry

Sebastian TroncosoI am originally from Santiago, Chile. I completed my undergraduate work and master's degree in mathematics at Pontificia Universidad Catolica de Chile. After earning my master's degree, I moved to the USA to pursue my PhD at Michigan State University. In Michigan I meet my lovely wife, Yira, and become a father of two beautiful children, Emma and Sebastian. During my 10 years of teaching I can just say that I love what I do, and I am thrilled to be part of Birmingham-Southern College family.

My current research is on arithmetic dynamics, with much of my work motivated by Morton-Silverman’s Uniform Boundedness Conjecture. Arithmetic dynamics is at the intersection between dynamical systems and number theory. If you would like to talk about my research, mathematics, or anything at all, please do not hesitate to stop by my office.

In my free time I like rock climbing, swimming, gaming and spending time with my family.
