Ariel Keller

I am a 5th year mathematics graduate student and a PhD candidate at Emory University.
Advisor: Ron Gould.
Curriculum Vitae: Keller_CV.pdf.

My research interests lie mainly in extremal and structural graph theory. I enjoy a variety of problems, especially those involving paths and cycles, matchings, colorings, and independence. I have also recently become interested in zero forcing. I am currently working on projects in zero forcing and rainbow matching, as well as some results concerning the existence of many chorded cycles in a graph. My dissertation work involves finding different degree sum conditions that are sufficient to imply a graph contains many disjoint cycles or chorded cycles.

Outside of Mathematics, I enjoy playing violin and piano, reading thrillers, and playing board games and RPGs.
