Keyes works at the algorithmic interface between parallel computing and the numerical analysis of partial differential equations, across the spectrum of disciplines required in the computation of aerodynamic, geophysical, and chemically reacting flows: modeling the physical processes, designing and analyzing iterative algorithms, and implementing them on advanced parallel computer hardware, with a focus on scalable solvers for emerging architectures that penalize communication and synchronization.
