Paul Baumeister is a HPC algorithms developer at Jülich Supercomputing Centre. After his PhD in physics at RWTH Aachen University, Germany, he moved into the fields of supercomputing and technical computing. His special focus lies on energy-efficient compute architectures, super-scalable algorithms and programmability of accelerated HPC hardware, in particular GPUs. His field of expertise includes but is not limited to lattice Boltzmann methods, atmospheric radiation transport on GPUs and electronic structure calculations.
