Rebecca Hartman-Baker, the acting group leader, is a computational scientist with expertise in the development of scalable parallel algorithms for the petascale and beyond. Her other research interests include inverse and ill-posed problems, numerical optimization methods, and developing effective techniques for training users of HPC resources. She joined NERSC from iVEC in Australia, where she coached two teams to the Student Cluster Competition at the annual Supercomputing conference, led the HPC training program for a time, and was in charge of the decision-making process for determining the architecture of the petascale supercomputer at the Pawsey Supercomputing Centre.
She began her career at Oak Ridge National Laboratory, where for her work on the initial implementation of load balancing in MADNESS as a postdoc she was on the R&D100-award winning team. As a scientific computing liaison in the Oak Ridge Leadership Computing Facility, she worked with a wide variety of scientific fields, including chemistry, nuclear physics, and logistics, and led the liaison task in the scientific computing group.
Rebecca earned a PhD in computer science, with a certificate in computational science and engineering, from the University of Illinois at Urbana-Champaign.
