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.

Computer science majors Anna Krolikowski ’20, Sarah Friday ’20, and Alice Quintanilla ’20 coauthored a peer-reviewed paper with Assistant Professor of Computer Science Jacob Schrum that was accepted to the EvoMUSART: International Conference on Computational Intelligence in Music, Sound, Art, and Design. Their paper, “Quantum Zentanglement: Combining Picbreeder and Wave Function Collapse to Create Zentangles,” presents a computational approach to generating art reminiscent of Zentangles. Examples of generated art are available here.

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.

Computer science major Sara Boyd ’20 has been selected as a finalist of the Computing Research Association’s (CRA) Outstanding Undergraduate Researcher Award for 2020. This award program recognizes undergraduate students in North American colleges and universities who show outstanding potential in an area of computing research. Boyd’s award recognizes published work she has done with Associate Professor of Computer Science Barbara Anthony, an REU at the University of Texas at Arlington, as well as project work in several computer science courses.
