Elise Walker - Research

My graduate research interests were in computational and numerical algebraic geometry. Specifically I found myself working with toric varieties and toric degenerations, numerical homotopies, Khovanskii bases, Newton-Okounkov bodies, and applications to chemical reaction networks.

My Ph.D. advisor was Frank Sottile .

Preprints

SubalgebraBases in Macaulay2

(with Michael Burr, Oliver Clarke, Tim Duff, Jackson Leaman, and Nathan Nichols)

Macaulay2 is a software system used extensively in algebraic geometry and related fields. We revived a software package for Macaulay2 which can compute subalgebra bases. More details can be found on the software package website.

Newton-Okounkov bodies of chemical reaction systems
