Undergraduate Research Advising

2018/2019: Henry Wix is currently writing his senior thesis on solving combinatorial problems using integer programming. 

2016/2017: Jack Wallace did an independent study on Algebraic Geometry and formulating combinatorial problems in the context of Algebraic Geometry. I also advised Catherine Cooper’s senior thesis on $t$-tone colorings in the Cartesian product of graphs.

Summer 2016:  My research advisees were Jacqueline Kromasch and Shriya Nagpal. Jacqueline studied using PCA, LDA, and k-means clustering to identify common manufacturing sources among 82 counterfeit pharmaceutical pills. Shriya’s project was on improving upon the class of graphs that satisfy Vizing’s Conjecture. Shriya presented her work at MathFest and won the Cur Award for her presentation.

Summer 2015:  My research advisees were Yaoqi Guo and Asa Tenney. Asa studied domination in the hierarchical product of graphs. He presented his work at MathFest and won an Outstanding Presentation Award.

Summer 2013: I was a research advisor in the Clemson REU in Combinatorics, Computational Algebraic Geometry, and Number Theory. My group studied 2-tone colorings in graph products. The students presented their work at the Southeast REU Conference. 

Summer 2012: I was a graduate student mentor in the Clemson REU in Combinatorics, Computational Algebraic Geometry, and Number Theory. My group studied classifying local fields of characteristic p. The students presented their work at the Southeast REU Conference.
