Algebraic design of experiments
Discrete models of biochemical networks
Gröbner fans of zero-dimensional ideals
Polynomial maps over finite fields
I am an Associate Professor in the Department of Mathematics at Cal Poly, San Luis Obispo. My research involves theoretical development and practical application of algebraic models of biochemical networks. I also work in algebraic design of experiments with the goal of determining the optimal amount and type of experimental data needed for algebraic model construction. The models used in this work are time- and state-discrete dynamical systems, described by polynomial functions over a finite field.
I am also a senior researcher at The Southeast Center for Mathematics and Biology (SCMB) which is an NSF-Simons Research Center for Mathematics of Complex Biological Systems (MathBioSys), with a core mission of catalyzing new cross-disciplinary collaborations between biosystems experimentalists and interdisciplinary mathematicians. My project is in collaboration with Melissa Kemp.
