Max Ruth

Biography

Maximilian (Max) Ruth received his PhD in Applied Mathematics from Cornell University in 2024. Advised by David Bindel, Max's thesis work was on numerical methods for analyzing Hamiltonian systems and symplectic maps. This work has applications to the design of stellarators, a type of plasma confinement device. Previous to this, Max obtained a BS in engineering physics and an MS/BS in applied mathematics at the University of Colorado Boulder, where he worked on nonlinear waves in thin-film ferromagnets.

Max's research interests lie at the intersection of numerical analysis, plasma physics, and dynamical systems. With the Center for Predictive Engineering and Computational Science (PECOS) at the Oden Institute, Max works on modeling and simulating a device known as a plasma torch. The plasma torch is an interesting example of a multiscale multiphysics device, where fluid flow, electromagnetism, electron kinetics, and ionizing reactions are necessary components of the model. Max specifically works on developing methods to solve the underlying Boltzmann equation. Simultaneously, Max is working with Prof. Joshua Burby on stellarator physics. Stellarators are non-axisymmetric devices that use strong magnetic fields to confine plasma, with potential applications as a nuclear power device. Max is currently interested in finding ways to modify and solve the magnetohydrostatic force balance equation to find better stellarator equilibria.
