I am currently working as an FPGA Developer focused on digital signal processing at Keysight Technologies in Santa Rosa, California.

In March 2022, I completed my Ph.D. in mathematics as a student of the Discrete Geometry and Discrete Algebraic Geometry groups at the Freie Universität Berlin.

Here is my CV.

My advisors were Christian Haase and Jean-Philippe Labbé.

I was a student of the Berlin Mathematical School and was funded through the Facets of Complexity research training group. My research was in discrete geometry and algebraic combinatorics. I had 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.
