## Expository talks aimed at undergrads

- Generating Functions and the Two Stamp Problem, an introduction to my research area.
- Cubing the Pyramid: or, Why We Need Calculus (and Measure Theory!), about dissections, the Dehn Invariant, and some motivating examples for the Banach-Tarski paradox.
- Squooshing the Cube: Can you squoosh a cube and make its volume larger? Largely based on Igor Pak's paper, Inflating polyhedral surfaces.
- Untangling Escher with Complex Arithmetic, analyzing his lithograph Prentententoonstelling. Largely based on Bart de Smit and Hendrik Lenstra's Escher and the Droste effect.
