Bio

Robert Saye is a research scientist in the Mathematics Group at LBNL. He held a Luis W. Alvarez Postdoctoral Fellow at Berkeley Lab from 2013 to 2017, received his Ph.D. in Applied Mathematics from UC Berkeley in 2013, and Bachelor of Philosophy with First Class Honours (2007) from the Australian National University in 2008. He is an awardee of the prestigious U.S. Department of Energy Early Career Research Program, 2021-2026. Other awards include the 2011 Cozarelli Prize (joint with co-author James Sethian) from the Proceedings of the National Academy of Science, the 2013 Bernard Friedman Memorial Prize in Applied Mathematics from UC Berkeley, and 2007 University Medal in Mathematics from the Australian National University.

Robert's research interests include numerical methods for multi-phase multi-physics in dynamic and extremely complex geometry; numerical methods for interface dynamics; high-order algorithms; and high performance computing. Examples include high-order discontinuous Galerkin (DG) methods; high-order algorithms for level set methods and implicitly-defined geometry; scalable and fast multigrid algorithms for elliptic interface problems and multi-phase Stokes problems; and high-order quadrature algorithms in complex geometry.

He develops and maintains the open-source code Algoim, a collection of high-order accurate numerical methods and C++ algorithms for working with implicitly-defined geometry and level set methods.
