Lee Ricketson received his Bachelor's Degree in mathematics from MIT in 2009 and his Ph.D. in mathematics from UCLA in 2014. He 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, sparse grid methods, finite volume methods, and simulation of kinetic plasma dynamics in general. His doctoral dissertation was given an Outstanding Dissertation Award by the Pacific Journal of Mathematics, and he received the Cathleen Morawetz Fellowship Award for outstanding postdoctoral scientific achievement during his time at Courant.
