I am a Ph.D. student in the Discrete Geometry and Discrete Algebraic Geometry groups at the Freie Universität Berlin.

My advisors are Christian Haase and Jean-Philippe Labbé.

I am a student of the Berlin Mathematical School and am funded through the Facets of Complexity research training group. My research is in discrete geometry and algebraic combinatorics. I have projects to study equivariant Ehrhart theory, combinatorial properties of simplicial hyperplane arrangements, and Ehrhart theory in tropical geometry. I did my bachelors in mathematics at the University of California, Berkeley.
