DMS assistant professor Songling Shan is bringing math to life for middle school students through hands-on activities that make abstract ideas visible and fun.

11/04/2025

As part of DMS assistant professor Songling Shan's outreach for COSAM's Destination STEM program, Shan uses 3D-printed graph models and colored tape strips to teach edge colorings in graph theory, a branch of mathematics that explores pairwise relationships between objects. “It’s one part of the beauty of graph theory,” Shan said. “You can make the subject visible so they can really see it. Even if it’s a smaller problem, they get the taste of what it is.” Her outreach is supported through a new National Science Foundation award, “Optimal Edge Decomposition of Graphs and Hamiltonicity of Tough Expanders.” The project tackles fundamental questions in graph theory — problems that sit at the intersection of mathematics, computer science and network design. Shan’s work aims to advance understanding of how complex systems can be broken into smaller, well-structured parts while also testing long-standing conjectures that have guided the field for decades.
