### Current Research Interests

Broadly speaking, I am interested in studying algebraic properties of geometric and discrete objects. Recently, these geometric objects have been arrangements of points in the projective plane and arrangements of lines in three-dimensional projective space. I've also been studying the interactions of squarefree monomial ideals with graphs. In education, I am interested in the use of mastery grading and inquiry-based learning to encourage my students to develop a growth mindset toward mathematics.
