Welcome to the University of St. Thomas Department of Mathematics!


Come Discover How Magical Mathematics Can Be


The Department of Mathematics recognizes both the inherent beauty in the discipline and the many areas of practical application of mathematics. Our faculty are active researchers and are fully invested in our students. We have several exciting programs and centers including: the Mathematics Resource Center (MaRC), which provides placement advising, testing and free tutoring, and the Center for Applied Mathematics (CAM), which provides the opportunity for meaningful undergraduate research and uses mathematics to solve real-world problems for business, industry and government. We offer several majors: B.S. in Actuarial Science, and a B.A. in Mathematics with specialties in Pure Mathematics, Mathematics Education, Statistics, or Applied Mathematics.

Latest News from the Department

UST students Alex Bates and Laura Fink will be giving a CAM colloquium. Join us Monday, May 2, in the 3M Auditorium (OWS 150), from 6:00 to 7:00 p.m. Cookies and beverages will be available.

Abstract: Zero forcing is a fairly new concept in mathematical research, with various applications in mathematics, physics, and the spread of information in networks. Zero forcing refers to the process of coloring the vertices on a graph by following a specified color change rule. Topics of particular interest for this research project are zero forcing sets, or initial sets which will eventually force or color all of the vertices of a graph, and the amount of time this process takes. Results of this research include upper and lower bounds for size of the initial zero forcing sets on circulant graphs of the form C[n, {s, t}]. Results also include insight into the specific nature of circulant graphs and proofs for the isomorphisms of certain families of circulant graphs.

Bio: Senior Alex Bates and sophomore Laura Fink were awarded the 2015 CAM Outstanding Summer Research Award. Alex and Laura worked with faculty advisor, Prof. Brenda Kroschel.

Professor Jim Bridgeman, from the University of Connecticut, will be giving a CAM colloquium. Join us Friday, April 15, in OWS 257, from 3:00 to 5:00 p.m. Pizza and pop will be available.

Abstract: Actuaries traditionally model the asset-liability risk (or interest rate risk) by using immunization (Taylor’s theorem) to examine stability of present value relationships on a balance sheet. We present a dual approach using Fourier analysis to examine the stability of on-going interest rate spreads over time in an income statement. Part I introduces Fourier analysis and convolutions and applies them to the future interest rate spreads implied by an idealized balance sheet. This suggests a completely new picture of the asset-liability risk. Part II explores a possible Fourier analysis of the external interest rate environment that sharpens this new picture of the asset-liability risk.

Bio: Jim Bridgeman is an associate professor of mathematics at the University of Connecticut, where he directs the graduate programs in actuarial science and financial mathematics. He has a Master’s degree from Yale and is a fellow of the Society of Actuaries. He had a varied 29 year career in the insurance industry before joining UConn in 2001.

Stuart Klugman, Senior Staff Fellow at the Society of Actuaries, will be giving a CAM colloquium. Join us Thursday, April 7, in OWS 150 (3M Auditorium), from 5:30 to 6:30 p.m. Refreshments will be available.

Abstract: For over 25 years, actuary has been ranked among the top jobs. At St. Thomas, students can major in actuarial science, yet no actuary refers to him or herself as an actuarial scientist. In this talk, the work of the actuary in support of the management of financial security systems will be presented in the context of the many fields (e.g., statistics, economics, finance, and marketing) that inform actuarial problem solving. Through several examples that illustrate actuarial work, an attempt will be made to see how scientific it is.

Bio: Stuart Klugman, PhD, FSA, CERA, is a Senior Staff Fellow in the education department of the Society of Actuaries (SOA), a position he has held since 2009. From 1974-2009, he was an actuarial science professor at the University of Iowa and Drake University. He is a co-author of the text Loss Models, used on actuarial Exam C and editor of two other exam texts. He served two terms on the SOA Board of Governors and is a two time recipient of the SOA Presidential Award.

St. Olaf professor Adam Berliner will be giving us examples of how we see and hear about math in activities we do every day. Join us Tuesday, March 8, in OWS 275, from Noon to 1:00 p.m. Food will be provided.

Abstract: In this talk, we'll survey how some pretty interesting and deep mathematics appears in activities we frequently do while relaxing, from watching TV to playing games.  We will see how logic, graph theory, and even a small amount of linear algebra can help us think about Magic Squares and Sudoku, or perhaps even win $1 million.

Bio: Adam Berliner is an Associate Professor of Mathematics at St. Olaf College. A native of Shoreview, MN, Adam graduated from Carleton College in 2002 and earned his PhD from the University of Wisconsin – Madison in 2009. His academic interests are in combinatorial matrix theory, graph theory, and issues in undergraduate mathematics education. In his spare time, Adam enjoys going to the gym, cooking & baking, and watching too much reality television.

St. Thomas alumni Jacki Marshall and Jacob Klimek will be talking about job opportunities for mathematics (and related) majors. Their talk is titled, Job Opportunities: Applying Analytical Skills and Statistical Methods to Health Care Policy. Join us Tuesday, December 15, in OWS 275, from Noon to 1:00 p.m.

Abstract: Jaclyn Marshall and Jacob Klimek, both alums of St. Thomas, will be discussing job opportunities at The Lewin Group, a health care consulting firm that is a subsidiary of United Health Group.  We support our clients, general Federal government agencies and state governments, with policy research and data analysis on Medicare, Medicaid and CHIP, health care financing, strategic workforce planning, health program evaluation, comparative effectiveness research and other important areas of the public health policy arena. The Lewin Group is a great opportunity to apply the economic, mathematical, and statistical methods you have learned in undergrad to a real world setting that ultimately impacts the lives and health of many individuals. Please come join to learn more about this exciting opportunity. There are opportunities at Lewin locations in the Twin Cities and Washington, D.C.

Bios: Jacklyn Marshall and Jacob Klimek are both alums of St. Thomas. Jacki received her Applied Mathematics degree in 2003. Jacob is a 2015 graduate with a Mathematical Economics major and Mathematics minor.
