Andrew Lumsdaine is an internationally recognized expert in the area of high-performance computing who has made important contributions in many of the constitutive areas of HPC, including systems, programming languages, software libraries, and performance modeling. His work in HPC has been motivated by data-driven problems (e.g., large-scale graph analytics), as well as more traditional computational science problems. He has been an active participant in multiple standardization efforts, including the MPI Forum, the BLAS Technical Forum, the ISO C++ standardization committee, the oneAPI Technical Advisory Board, and the SYCL Advisory Panel. Open source software projects resulting from his work include the Matrix Template Library, the Boost Graph Library, and Open MPI.
