Undergraduate Mathematics Day

A day to celebrate and share mathematics research by undergraduates, Undergraduate Mathematics Day will be held:

NOV. 6, 2021

This year’s conference will be held in a hybrid mode with all presentations being delivered via Zoom. Participants who are able to present live will deliver their talks from the classroom computer which will be hosting the Zoom session. Participants who are not able to present in person will log into the Zoom meeting for their session and present from their own computer. You do not need to have Zoom installed to participate, as Zoom provides a Web address to log on.

At the present time, it is uncertain whether participants who are not members of the UD community will be able to join us on campus due to Covid restrictions. A final decision may not be made until shortly before the conference, so outside participants should plan on presenting and viewing sessions via Zoom. This event will be synchronous. 

In addition to the two plenary talks listed below, we welcome contributed talks on mathematics subjects of interest to undergraduate students. Undergraduate, high school  and graduate students are encouraged to give presentations on any mathematical topic. Talks can be on the learning and teaching of mathematics, the history of mathematics and applications to disciplines related to mathematics.

Plenary Talks

The 21st Annual Kenneth C. Schraut Memorial Lecture: One Health: Connecting Humans, Animals and the Environment


Abstract: 'One Health' is a multidisciplinary approach to improving the health of people, animals and the environment. Environmental, wildlife, domestic animal and human health fall under the One Health concept. Mathematical models of infectious diseases involving animals, environmental features and humans will be presented. These models can suggest management policies and predict disease spread. Examples including La Crosse virus and Zika virus will be discussed.

About Dr. Lenhart: Suzanne Lenhart is a Chancellor's professor in the Mathematics Department at the University of Tennessee. She was a part-time research staff member at Oak Ridge National Laboratory from 1987-2009. Her research involves partial differential equations, ordinary differential equations and optimal control of biological and physical models. She was the President of the Association for Women in Mathematics in 2001-03. She received fellow awards from SIAM, AMS, AWM and AAAS. She was the Associate Director for Education and Outreach of the National Institute for Mathematical and Biological Synthesis for the last 12 years. Lenhart has been the director of Research Experiences for Undergraduates summer programs at UT for 27 years.

The Crossings of Art, History and Mathematics


Abstract: In July 1944, Paul Turn worked near Budapest in a concentration camp brick factory. The challenges the workers faced when carting bricks from the kilns to storage areas led him to consider minimizing rail line crossings. Around 1958, artist Anthony Hill began investigating a similar question, how can a set of dots with all possible lines between them be arranged to have the fewest line crossings? These informed the foundation for major open conjectures regarding graph crossings. This talk will discuss the mathematics around these conjectures, related results and open problems.

About Dr. White: Jennifer White earned her bachelor’s degree in mathematics and education at the University of Dayton. She then earned her master’s and Ph.D. at the University of Colorado, Denver. Her research interests are in graph theory, and she is currently an Associate Professor at Saint Vincent College. She is a Project NExT fellow in MAA.
