Assistant Professor

Dr. Erickson received her B.A. and Ph.D. in mathematics from North Dakota State University where she completed her dissertation titled “The Game of Nim on Graphs.” She has been the recipient of numerous fellowships including three from the National Science Foundation — one of which placed her at the Alfred Renyi Institute in Budapest, Hungary, as a Mathematics Research Fellow studying combinatorics in 2010. Prior to coming to Augustana, Erickson served as a visiting assistant professor in mathematics at Concordia College in Moorhead, Minnesota.

Martha Gregg

Martha Gregg
Department Chair and Associate Professor

Dr. Gregg teaches a wide variety of mathematics courses. Her research interests are in the area of functional analysis; specifically she studies a class of completely positive maps on C*-algebras. She received her Ph.D. from the University of Nebraska at Lincoln.

Carl OlimbCarl Olimb
Associate Professor

After receiving his Ph.D. from Montana State University, Dr. Olimb served as an Assistant Professor at Southwest Minnesota State University. While there, he taught a wide array of courses while focusing  on math education. His primary research interest regards content knowledge for preservice teachers. Secondary interests include topological data analysis and cohomology of tiling spaces. While not teaching or working on his research, Dr. Olimb enjoys a game of chess.

Curtis Olson

Curtis Olson
Visiting Assistant Professor

Dr. Olson frequently teaches "Pre-Calculus," "Calculus I," and "Calculus II." He completed his D.A. at Idaho State University in the area of matrix theory. Dr. Olson retired from the University of South Dakota, where he served as chair of the mathematics department. He is active with the South Dakota Council of Teachers of Mathematics and is a founding member of the Sioux Falls Area Math Teachers Circle.

Tim Sorenson

Timothy Sorenson
Assistant Professor

In over twenty years on the mathematics faculty at Augustana, Dr. Sorenson has taught a wide variety of courses in the department, as well January term courses in "International Relations" and "Genealogy Research." His research is in abstract algebra. He received his Ph.D. from Kent State University. Dr. Sorenson is an enthusiastic bridge player; he and his wife have spent many an evening in fierce competition with the Smiths.


Marlys Vant Hul

Marlys Vant Hul '94
Division Coordinator

Marlys has worked at Augustana for more than twenty-five years. She and her two daughters are Augustana grads. Marlys is also the Science Day coordinator, which brings about 300 high school junior and senior students to campus every fall for a day of hands-on science experiences. Marlys thoroughly enjoys the students; it is a privilege to be surrounded by  the very best university students and watch them grow throughout their four years at Augie. Marlys loves to shop, garden, read and spend time with her grandchildren.


Emil Knapp

Emil Knapp
Professor Emeritus

Over his forty year tenure at Augustana, Dr. Knapp taught virtually all of the courses offered in the department. In recent years he often taught "Quantitative Reasoning," "Foundations of Mathematics," "Calculus III," "Probability and Statistics," and "Senior Seminar." He received his Bachelor’s degree from Concordia College - Moorhead and his Ph.D. from the University of Minnesota. His thesis developed a generalized theory of distributions, and his latest research interest is three-body stable orbits. Dr. Knapp is also a triathlete, and finished this summer's Hy-Vee triathlon in under four hours — a personal best!

Jay SmithJay Smith '67
Assistant Professor Emeritus

An Augustana faculty member for over 30 years, Jay Smith frequently taught "Calculus I" and "Calculus II" as well as required math courses for elementary education majors. He is an Augustana alumnus, and did his graduate work at University of South Dakota and Montana State University. Jay can frequently be found at Zorbas at Otter Tail Lake in the summer, or at Old Chicago in the winter.
