The Department of Mathematics and Computer Science was active at the Joint Mathematics Meetings, with national meetings of the Mathematical Association of America (MAA), the American Mathematical Society (AMS), the Association for Women in Mathematics (AWM), and more. It is the largest meeting of mathematicians in the world. The meetings were held in Denver, CO, January 15–18, 2020.

• Sarah Friday ’21 and Jordan Smith ’20 presented “Diagonalizing the Undiagonalizable,” research based and expanding on a 2019 SCOPE project with Professor of Mathematics Fumiko Futamura. Aaron Waclawczyk ’21 was a coauthor who helped extend the SCOPE work. The presentation was in the AMS contributed-paper session on algebra and algebraic geometry.
• Daniela Beckelhymer ’20 presented her mathematics capstone project titled “The Costs and Rewards of Pursuing Different Postsecondary Degrees“ as part of the undergraduate poster session. Professor of Mathematics Alison Marr supervised the project.
• Marr presented “Choose Your Own Adventure: An Analysis of Interactive Gamebooks Using Graph Theory” in the MAA contributed-paper session “Tell Me a Story: Connections between Mathematics and Performed or Print Narrative.” D’Andre Adams ’21 and Beckelhymer are coauthors.  The presentation was based on their 2017 SCOPE research and their subsequent publication.
• Marr coorganized the MAA contributed-paper session on re-envisioning the calculus sequence with coorganizers Robin Cruz, College of Idaho; Tom Halverson, Macalester College; Joel Kilty, Centre College; Alex M. McAllister, Centre College; and Chad Topaz, Williams College.
• Marr was a coauthor of the talk “Calculus: Origins, Reforms, and New Directions” with Robin Cruz, College of Idaho; Tom Halverson, Macalester College; Joel Kilty, Centre College; Alex M. McAllister, Centre College; and Chad Topaz, Williams College.
• Marr and Assistant Professor of Mathematics John D. Ross presented the preliminary report “A Re-Envisioning of the Calculus Sequence for the Modern Student” with coauthors Joel Kilty, Centre College, and Alex M. McAllister, Centre College.
• Ross presented “Exploring Big Ideas in Calculus 1 through Bite-Sized IBL Lessons” in the MAA contributed-paper session on inquiry-based learning and teaching.
• Associate Professor of Mathematics Therese Shelton copresented “Building Community through Systemic Initiative for Modeling Investigations and Opportunities with Differential Equations (SIMIODE)” in the MAA poster session on projects supported by the National Science Foundation (NSF) Division of Undergraduate Education. Her coauthors were the coprincipal investigators of their NSF grant: Brian Winkel, SIMIODE and emeritus professor from the U.S. Military Academy at West Point; Richard C. Harwood, Newberg University; Audrey Malagon, Virginia Wesleyan University; and Patrice Tiffany, Manhattan College. The NSF grant partly funded Shelton’s attendance. Shelton served on the SIMIODE Board of Contributing Advisors, as well as participated in a meeting of her NSF grant coprincipal investigators.
• Shelton coorganized the AMS special session “Wall-to-all Modeling Activities in Differential Equations Courses.” Her coorganizers were Janet Fierson, La Salle University, and Brian Winkel, SIMIODE.
• Shelton participated in the meeting of the national MAA Committee on Sessions of Contributed Papers.
• Visiting Assistant Professor of Mathematics Safia Chettih presented the preliminary report “A Combinatorial Model for an Honest ∞-Operad” in the AMS special session on computational and categorical methods in homotopy theory. Her coauthors were L. Bonatto, University of Oxford; A. Linton, University of Southampton; S. Raynor, Macquarie University; M. Roberston, University of Melbourne; and N. Wahl, University of Copenhagen.
• Visiting Assistant Professor of Mathematics John M. Osborn also attended.

Professor of Mathematics Fumiko Futamura coauthored an IBL-style textbook titled Perspective and Projective Geometry  (Princeton University Press, 2019), with her colleagues Annalisa Crannell, of Franklin & Marshall College, and Marc Frantz, of Indiana University. The textbook introduces students to geometry through perspective drawing, leading students to discover ideas through hands-on activities, including drawing, analyzing Renaissance paintings and photographs, and GeoGebra constructions. The textbook also guides students to develop rigorous proofs for their conjectures and can be used as an introduction to proofs course for undergraduate math majors.

Professor of Mathematics Fumiko Futamura was the inaugural speaker at the newly formed Women in Science and Engineering (WISE) Club at Anderson High School in Austin, TX. She shared her experiences and reflections on getting her Ph.D. in mathematics as a Japanese woman and spoke about her research in math and art.

Professor of Mathematics Fumiko Futamura, along with coauthors Annalisa Crannell of Franklin and Marshall College and Marc Frantz of Indiana University, published an article “An (Isometric) Perspective on Homographies” in the Journal for Geometry and Graphics (vol. 23, no. 1, pp. 65–83).

The Department of Mathematics and Computer Science was active at MathFest, a national meeting of the Mathematical Association of America (MAA), held this year in Cincinnati, OH, July 31–August 3, 2019.

• Professor of Mathematics Alison Marr and Daniela Beckelhymer ’20 led an activity titled “Domino Antimagic Squares” in the MAA Workshop Create and Recreate: A Celebration of Women in Recreational Mathematics.
• Marr copresented “Beyond Leaky Pipes: Fostering Pathways and Persistence in the Mathematical Sciences” with Joel Kilty and Alex M. McAllister, of Centre College, and Ranthony A.C. Edmonds, of Ohio State University, in the session “Diversity, Equity, and Inclusion in Mathematics,” which they also coorganized.
• Beckelhymer participated in the Mentoring Workshop for Women.
• Professor of Mathematics Fumiko Futamura organized and led a minicourse, “Visualizing Projective Geometry through Photographs and Perspective Drawings,” with her collaborator Annalisa Crannell, of Franklin & Marshall College. This was the sixth offering of the highly successful national expert class, sponsored by the MAA special-interest group on Mathematics and the Arts.
• Associate Professor of Mathematics Therese Shelton presented “DE and Social Justice: A Cholera Model with Bacterial Reservoir,” coauthored by Emma Kathryn Groves ’18 and Associate Professor of Education Sherry Adrian, in the session “Showcase of Modeling to Motivate Differential Equations,” coorganized with Patrice Tiffany and Rosemary Farley, of Manhattan College, Riverside, NY.  Shelton and Tiffany are among the coprincipal investigators on a grant from the National Science Foundation that sponsored the session.
• Shelton participated in the full-day meeting of the national governing body, the MAA Congress, as the new representative from the Texas Section of the MAA. Shelton was elected as recorder for the MAA Congress (2020–2022), and she participated in the MAA Section Officers Meeting.
• Shelton coorganized the general contributed poster session with Steven McKay, of Brigham Young University, Provo, UT, as members of the national MAA Committee on Contributed Paper Sessions.
