Lee Ricketson conducted his postdoctoral work at the Courant Institute at New York University before joining Lawrence Livermore in 2017. In his career, he has developed expertise in multilevel methods for stochastic differential equations, particle-in-cell schemes, asymptotic- and structure-preserving methods, sparse grid methods, finite volume methods, and simulation of kinetic plasma dynamics in general.
