Dr. Pieter Boom
Dr Pieter Boom is an assistant professor in Mechanical Engineer at KFUPM and is affiliated with the Interdisciplinary Research Center for Construction and Building Materials. His research interests lie in the development of provably robust and efficient numerical methods for massively parallel engineering simulation of non-smooth multiphysical phenomena. Dr Boom earned his PhD in aerospace science and engineering from the University of Toronto in 2015. His dissertation focused on the generalization of summation-by-parts finite-difference operators and the optimization of high-order implicit time-marching methods for unsteady computational fluid dynamics. He was then appointed as a postdoctoral fellow on an Airbus funded project at the University of Toronto (2014-2018) investigating the use of synthetic jets for turbulent boundary layer drag reduction. Finally, prior to joining KFUPM in January 2022, Dr Boom worked as a postdoctoral research associate on an UKRI-EPSRC Fellowship and as an investigator on an ARCHER2 UK National Supercomputing Service grant at the University of Manchester (2018-2022). In this role he was the first to fully describe linear elasticity and thermal diffusion in media with evolving discontinuities using discrete exterior calculus (DEC). He also developed a parallelized software library implementing DEC with excellent scaling on over 10k processors.
