Expository Math Writings
- Hidden trees in the forest: On lattice points and prime labelings of graphs. This paper was inspired by my one-week residency at an AIM-NSF workshop called "Research Experiences for Undergraduate Faculty" at ICERM in Providence, RI, in June 2012. It contains some of our unpublished results, and also includes exercises and project ideas that faculty can use to involve undergraduates in research in the areas of Combinatorics, Graph Theory, and Number Theory (2012). (Available by clicking here).
- On a coin-flip problem and its connection to pi. I wrote this with the intention of using it as a teaching (learning) tool for other faculty (students). Hence many exercises are included (2011). (Available by clicking here).
