Stuart R Slattery

Computational Scientist

Dr. Slattery’s work focuses on the research, development, implementation, and application of massively parallel algorithms for multiphysics and multiscale simulations, radiation transport, hydrodynamics, solid mechanics, and the modeling of various energy systems. This includes the development and application of methods in sparse and dense linear and nonlinear algebra, PDE discretizations, computational meshes, particles, and time integrators. Dr. Slattery leads exascale development efforts in both software technology for multiphysics and multiscale coupling as well as co-design and application efforts for the development of particle methods for hydrodynamics and solid mechanics. He also contributes to scalable algorithm research for particle methods in radiation transport. These efforts develop scalable, performance portable libraries and applications targeting next-generation supercomputers and impact multiscale and multiphysics simulations in DOE in areas including electric vehicle batteries, additive manufacturing, and nuclear reactor analysis.

Dr. Slattery earned his Ph.D. in Nuclear Engineering and Engineering Physics at the University of Wisconsin before joining ORNL as a member of the scientific staff in 2013.
